putting my healthy small block in my dually and debating on keeping it old school belt setup or putting the serpintine belt setup on it. they both have pros and cons but it just seems simpler to keep it old school. and if the power steering takes a crap it will be easier to change and the old school alternators are cheaper. What would you guys run if it was you?
v belts
No way frank, serpentine is the way to go. I have yet to sling a serpentine belt or have any kind of problem.
Serp... and you can get a serp although for same price as vbelt. No slipping no squealing. No thrown belts with serp. Very rare to throw or break one. Only Don side to serp is if the belt does go you loose everything
SERP WONT THROW OFF WHEN IN HIGH RPM'S
Serp won't throw and also takes less tension to keep it from slipping, less tension means less wear which means bearings last longer
serp
serp all the way.

v belts
thats my preferance the last time i put a alt on my dd 94 truck it was twice as much $$ than a old style single wire my buick scroad master ate belts and there was no way too shim anything out just my 2 cents if ya doo run a serp setup from somethin else make shure you write down somewhere under the hood what it came off for referance of replacement parts down the road

soo thats what everyones running ??? i havent ever had any trouble with v belts but on the other hand ive changed countless tensioners
awh geese, unamious decision serpintine wins for now. as long as the brackets line up with the dart pro series heads. seeing how they are angled i dont know if it will matter.
i agree with you bigfrank way less problems and everything is cheaper without all the bs. plus probably more hp old school.
I would say serp would produce more HP, one belt with flatter contact patch, and self adjusting, so you know you have proper tension on all pulleys, compared to v belt with multiple belts with deep contact, and being pulled from every direction with uneven tension on each separate belt... But just my 2 cents
Big frank...I'm guessing your scroad master had a ps pump changed and someone cranked the pulley on too far, that's the only time I have shredded a serp belt

That has to do with amperage output more so than the application year.
dosent make a difference either way too me ;D ==nta everybody has a opinion did anyone ask if the dually truck has serpentine belt already
Sounded like dually had serp, new motor doesnt...yet
it had serpintine setup on it and it's got it on it for now. got it running today and it sounds pretty sweet.
V belt
I have a 653 big block Merlin. 1,000hp-1,000ft lbs. it hits like 6800. Never tossed a belt
I have a drag boat 454 8-71 supercharged. 1,000hp, v belts 7,500 rpm
Another drag boat 482 16-71, 2,500hp we run on the lake with an alternator, vbelt @ 7,800rpm
Never had a problem with any of them slipping off.
My truck is soon to have v belts, I'm sure they will be fine too. And plus, if I do loose a belt, at least I don't loose everything.
But, we only drag race. In the mud, there always a different load, constant rpm change, and just the roughness of the ride. As to drag racing, the only huge load is off the line, then after that it's just top end, and realistically it's for a few seconds. As to bogging were you in the pit god only knows how long. So I'm sure that also determines the life of the belt, and how prone they are to popping off.
But just MY PERSONAL EXPERIENCE WITH V BELTS, never had an issue.
dont some of the serpentine setups use a different water pump that turns backwards???
well guess i should have went old school. the belt tensioner is screwed already so my belt keeps flipping on an idler pully chewing up a $15 dollar belt and what's a tensioner? about $40 :( oh well i guess.

yes, the ones with a tensioner
well serpintine definately is not the way to go! damn sbc is got too much for it. blew p00 all up! lol Somehow the pulley came right off the shaft of the water pump. And the water pump is like brand new.
I see the problem...that fan is running backwards

really? the side that says "front" was facing the front of the truck and radiator. is "front" front of engine? damn if that's the case... usually on flywheels it says "engine side" or what not. guess i took that wrong. that's the way it was before i got it? bad part is i figured it was correct!
Serpentine is spinning the water pump and fan backwards now

so on an old school motor with a different water pump it goes on the way i had it? for this pump it gets turned around?
nope you can't do that... flip the fan around. What it means is it's got the wrong fan on it and i need to get a new clutch fan that's made to turn in that direction. well that sucks it cost me a radiator, probably need a new water pump and gotta buy a clutch fan. :(
on factory serpintine belt set up, if the pulley has v grooves for the belt standerd rotation. (old school) smooth pulley means reverse rotation water pumps.
Junkyard electric fan is easiest route

x2 damn that was an expensive lesson.
you hit it prograde! expensive lesson. story of my life lol

i did the same thing on my old monte ss on a fresh 350
well i suppose i could get out of it cheaper by putting the old school setup back on it. the fan would work right with the old water pump. main ass chapper is the nice 4 core radiator toasted! i got a couple little radiators but really dont wanna put em in there with that motor and for towing.
