Alright, so I have a 90 chevy socttsdale, std cab 8 ft bed, and It has the IFS, and I want to lift it, the lift kits for it are your know 1000 to 1500 bucks and the biggest you can buy is 6 inches, so has anyoine heard of anyone putting leafs on the front makes it a stright axel like the earlier chevys? cuz then I could lift it higher and it would cost me a whole lot less, and it would be a rougher ride, but still could drive it everyday... or anyone have any pics on how someone lifted the IFS themselves.... bigger then 6 inches???

Its called a SAS solid axle swap, and yes it has been done and it is done a lot, there is a lot of info it just do a search on chevy sas, and I thought scottsdale p/u were in the 70's? then changed to silverado? I could be wrong tho just never heard of a 90 scottsdale,
sas is 1000x better than ifs imo, and worth the time and money. if I were you dont go wasting your money on the ifs lift kit.
simple put
ifs lift- gets you a limited amount of lift, and with any lift you run bigger tires, and with bigger tires = more stress on halfshafts =breakage =more money= getting mad and no fun
sas= unlimited amount of lift options and axle options= biggest tires you can afford= lots of fun lol plus it is so much stronger, sure you will eventually break somethin but not like ifs
Yea I have an 83 Scottsdale 3/4 , So I know about the Solid axle , And sounds good to me I think I am going to do it, And Yea its a 90 scottsdale, According to the factory tags in the glove box, i looked it up on my GM tech website, and It was built in 1989 and rolled out the pontiac assembly plant, lol with a a scottsdale package, I just dont like the term Heavy 1/2 ton, i think it was stupid idea, to put all 3/4 ton suspention and 1/2 6 lug axles, but hey I didnt make it i just fix , modd and drive it... lol

thats cool I learned something new :)
If you do it you have to have a ford front axle because your tcase is on the drivers side or change your tcase to run a Chevy axle
wait so because, I have a chevy I have to put a ford axle why cant I flip the chevy axle, ??? Thats weird, And i have a 373 gear in the back now. do I have to put a 373 in the front?
and if I do the ford, can i use the drive shaft I have now?
You just can't flip an axle. When Chevy went to ifs it switched to driverside tcase. All Chevy straight axles are passenger side. And yes you want to match front and rear gears
im in the process of doing a sas right now your going to want to find a 78-79 ford f250 high pinion
I was doing a lot of research and I can use dodge axles and they are 6 and 8 lug , unlike ford is 5 and 7 lol. So I am going to do the sas, as soon as I get my hands on some 3/4, 8 lug dodge axle, I will deff post pics and update anyone who wants to follow in the garage projects.....
Lol. P.s Ice87 I was joking about the flipping the axle...lol
no get a ford f250 high pinion axle they come in 8 lug...
Thank god. I would say I agree go ford 3/4 axles high pinion will help out driveshaft angles.
a half ton ford axle can be swapped to 6 lug very easily, all ya gotta do is swap out the hubs. and u can use any for axle, a high pinion will just be better for ya in the long run, i did my sas with a low pinion and i had to take the die grinder to the pinion yoke to clearence it for the steep angle at full droop but u can also just use degree shims to roll the axle downwards to help with pinion angle. yes you can use the driveshaft u have now, you just need a combination ujoint cuz d44 yakes have a smaller cap size than the chevy's ifs. SAS is the way to go, little more work involved, but worth it 10 fold in the end
heres the link to my whole build:

full size dodge axles are not 6 lug theyre 5x5.5 same as full size fords. dakotas and durangos are 6 lug but theyre ifs too. All older model 8 lugs are pretty much the same anyway I think. Didnt ford change the 8 lug pattern sometime in 2000ish?
Yea I was mistaken, the dodge are 5 x5.5 but I was looking at dodge 3/4 8 lug with the 4.10's and I think i am just going to do both, front and back, i think i would be better then getting a ford 5 lug and changing the hub, also I wanna run 38x16.5x16 so I figured the 410 would help turn the tire a little better then the 373 thats in my Chevy IFS now... I am going to do some slight mods to the motor but not much, I got a whole new exhaust, headers, and i got 305 heads, with a little heavier springs in them and the OE chevy stamped steel rockers.... Do to the fact mine is a TBI i am looking into a new bolt on TBI upgrade to 670 cfm... and a high rise intake, and I want to know if the high rise with the TBI would make it any better or i guess if it would be worth the 2800 bucks...lol I figured some where in the high 300 low 400's for HP... you know port and polish I am going to get as much as I can...
Imo id get rid of them tbi heads if your looking to make any serious power
i got some 305 heads off an older chevy, I do dont believe they had TBI back them I am pretty sure mid or late 80's is when they came out with the 1st yr TBI...
305 heads aren't any better they just have smaller combustion chamber
Learn something new everyday I guess... Thanks Man I guess, I have never really modded a TBI motor... so I am going to have to do some more research...
you can also adjust your fuel psi on your stock tbi to get more fuel, the fuel pressure regulator is built in to the housing the injectors are bolted to, and it is adjustable :)
Modding a tbi is the same as the older engines its just those heads don't flow. Get a set of vortec heads and and intake (has to be vortec aftermarket intake bolt holes are different) a nice cam and ur not to far from ur hp ur wanting and it'd be fairly affordable
From what I have been reading Chipping it can also increase hp heres one, that I was reading about, what do you guys think about this? has anyone done it or heard about it? and I am not sure if I want to re-cam it... I havent thought about it yet... but vortec heads off any yr Chevy or certain yrs? and Will my TBI bolt on to it??
http://autochipsdirect.com/chevrolet-c1500-71 (http://autochipsdirect.com/chevrolet-c1500-71)
No you will have to get a new intake and carb it. Any 5.7 vortec I think some years were better than others. Idk anybody who's put money into the tbis
Idk about that chip the increases all say "up to" I doubt that when u get it hooked up u will see much of a difference than before
tbi heads do not flow!! i put a 355 with old carb 2.02 heads in my tbi truck i had to angle the middle intake bolt holes out for the new stile tbi intake but it ran good that truck reved
It has 2.05 heads on it now, and I could port and polish and just replace the intake and put a 4 bar 670 cfm on it, do you think that would make for more hp?
And as far as the chip your prolly right, But hey its 60 bucks, I figured it would be worth asking if anyone has ever done it...
2.05 tbi? Are they factory?
get yourself a TBI spacer, goes under the TBI unit, you'll gain alittle mileage and
hp
And to answer somebody elses question, the SCOTTSDALE trim package was offered by GM from 1975-1991-2
Yea am pretty sure there factory, I am not 100% thogh, I am going to pull the block id in a little while and I will be able to tell you for sure then..
So I was thinking when I work up this morning......
Why couldnt I make those brackets work.... the front bracket bolt to the bottom of the frame correct. and If I needed to I could make it a little stronger. But 4 bolts or weld it to the frame would be good right.... ==noob
http://www.lmctruck.com/icatalog/cc/full.aspx?Page=148 (http://www.lmctruck.com/icatalog/cc/full.aspx?Page=148)
Sounds like it would be easier and cheaper to do all the stuff you want to do if you just sell this one and buy a mid 80's pickup lol
Yea.. It prolly would be, But this truck has been in the family for a long time... so I would like to keep it...

umm it might be cheaper to just buy a kit
there like 40 bucks a peice from lmc truck, I think i am going to give it a try, then weld some kind of tube across to stability, I'll post pics and let you guys know.
T.B.I is silly. Thats what ive got on my ramcharger and im switching to a carb setup asap. From what ive read theres not alot you can really do with them. Cause if you build your truck to the nuts you can only get so much fuel without that $2Kish tbi kit. The good thing about chevy is theyre everywhere. I'd buy a mid 90's wrecked/rolled chevy 3/4 ton 4x4 pull the vortec and computer out junk that tbi youve got drop the vortec in your truck and the only reason i say 3/4 ton is so you can snag you a set of 3/4 straight axels (does chevy have straight axle in there 3/4 tons like dodge?). Then part out whats good on the truck and almost break even when scraps high. You can build the p00 outta that old tbi motor and i bet you end up with the same if not less than a stock vortec. It wouldnt matter what side drop the front axle was cause youll have the matching t-case. Dodge 3/4 ton fronts are coil sprung if chevy is too get a 3'' spacer and a 4'' block for the rear. With those 3/4 springs youll already be 2'' or 3'' higher so that gives you all the power you need from your vortec, 5'' to 6'' of lift and your SAS swap for prolly less than $2,000. This is just my opinion though. Everything looks good on the internet lol but my truck still sets in the driveway with 1/2 alxes and a junk TBI system that hasnt run right in fo 'eva. Good luck bud I wish your build the best.
Gm hasn't used a solid axle in years. 1987 was the last year even in the 3/4 and 1 ton trucks
Well to start out, get with "disturban" on if ya wanna stick tbi. He knows all about it and he's done the research. Motors are one of those things that ur gonnaget outta it what ya put into it, there's no cheap way to build big power. Build it on what ur wallet can handle, not what hp u want
As for the sas, after 92 NO chevy truck had a solid front axle unlike ford and dodge. Take the time, find the right ford axle, it'll be worth it in the end, that way there's no swapping tcases or anything. The less ya have to change the easier it makes it all. Yes you could use those brackets and support em with a bar in between, but it wouldn't be as strong as you may like, those brackets were designed to be supported top and side by the frame rail, not just a small section on the top. IMO take the time and make ur own out of heavy steel and it will be a helluva lot stronger and safer. Ya gotta remember ya gotta dd this thing and all the forces that come with it. Braking pulls downwards on those front brackets enough where I've heard some guys ruin their frame horns
yea i have a cousin, who made a set for his bog truck.. and I am thinkin if his held up to his 700 hp 454 big clock bog truck they will be just fine for me so were going to get together tomorrow and talk it over, then i will go get some steel and we will start building.... As far as the axle if I go down to part glore and pick up some axle for 300 bucks my only problem is I dont know how to tell what gear is in that axle..... can anyone help me with this? and as far as my motor i blocked my egr. i am going to get a different air filter set up, put new true dual 3" exhaust with new headers and everything. and put a spacer on my tbi i am hearing rumors of low 300's for HP and I am good with that for now and its wont cost me a whole lot....
8)
Put a mark on the rotor and spin the pinion. Count the turns. 4 turns to 1 would be a 4.10...I think that's right lol
Yea I wanted to avoid that...lol but i can do it that way, then i can see the stamp case to see if its posi or not
i dont knpw a lot of any thing about chevys and what year they did what. HEY! get a dodge and all your problems will be solved. straight axle and all the power you need! lol oh, and theres an easier way to check for posi. just hold it to the floor, maybe turn a few times and check for one mark or two.
ok i just answered my own question.,
yes the pinion 4 times to 1 would be a 4.10 and a posi if you spin on side the other side should spin the same way as long as the pinion is stationary ( in park or holding with a screw driver or something ) and if it spins the opp way it would be an open diff....

A lot easier, if he wants everything to work the same. So many differences between 73-91C frames and 88-98 frames, everything from the fuel tank to which side the brake lines are ran. Its all different.

. . . solid axles were used by GM up until 1991 in the classic trucks, crew cabs, and Suburbans, blazers. Also all 3500HDs from the 88-98 bodies had solid axle (beam axle for 2wds, diff axle for 4x4s) until they were discontinued in 2000.
Yea but prolly 99% of gm trucks after 87 were ifs.

If you got a crew cab, suburban, jimmy, or blazer, or chassis cab, they could be solid axle. That's a lot of solid axle trucks from 88-91. 1992 and on, yeah all but the 3500HD were ifs.

I'm pretty sure high rise intake performance range is really high RPM's. So if your motor is not built to run ion the 4000 to 5000 rpm area it really wont do you much good. For boggin and stuff like that youre gonna want a dual plane. Thats what i was told anyway.

I wonder if dodge has that? Something to google i guess
