big small block

[tnbt78]

started gathering parts for a build. it will be a bowtie block bored 4.125 with a four inch stroke. all forged components with about 12 to 1 compression gonna use my bowtie heads and intake, the heads are angle plug and been cutto about 60 cc chambers and 2.02 intake and 1.6 exhaust. gonna order a 4-7 swap roller cam with 630 lift and 276 duration on the int and 284 on the exh. at .050 and on a 107 center line. all this should produce big block numbers at a small block weight and money. i think it will turn 44 cut boggers and 1 tons just fine in my s10. truck is all s10 except running gear even using the s 10 frame after boxing and reinforcing. what everyone think about the combo and any ideas about carb cfm. hoping this will rip will try to get pics up soon but this will take some time due to a new house and shop equipment

[Jjay78]

i'd say probly a 800 cfm edelbrock, or a holley 750 double pump depending on how much fuel you wana use and how fast lol, sounds like a killer combo

[betterbeaters]

850 holley man sec. !!!!!!!!!!!!!!!!!

[BOGIN4D9]

quadra jet!!!!!!

i got that same cam in a 388 stroker sbc  with the same compression too   and i run a 830 professionally tweaked and im thinking about tring a bigger carb  motor seems like it has more to give

850 Holley double pumper dual feed.

[ddmachine]

it depends on how well your heads flow run a 1050 on the last 434 that we built

the 4/7 swap cams are junk IMO

[MR NASTY]

Ya and what's his opinion based on, extensive dyno time, the hundredss of motors he builds a year or just general bs...

sounds wicked

the 4/7 swap cams are junk IMO

I am assuming u run a circle track car and if u don't like them 4/7 swap cams u are just like the rest f my roundy round buddies.. they tell me they don't like the swap cause it smoothes the tourque curve out. They want a broader tourque curve to get their cars moving out of the corner quicker. I don't know if its true but that is why they tell me they don't like them

[cnoswalt78]

why not try a boat cam? vary strong tq curve?.........................My buddy used the 630 setup and tunnel rams with 2 500s and a 400 shot in a 1966 nova (off the transbrake it twisted the frame) Make sure you port the hell out of them, but i dont think there guna flow you want a head that will put out over 200 becouse you have lots of cubes and big pistons dart 215s would work!

[Mudbuster]

your setup sounds real close to mine but a few differences,

mine is 4.030 bore, 3.75 stroke (383), 2.02/1.60 aluminum heads with 200cc intake runners, 256/260 duration (If I remember right) .640 lift, solid roller, torker II intake, 64cc chambers, 12.5:1.

Now I'm running an 850 demon manual secondary double pumper and the motor loves it I just ran a set of cut 44 hawgs with 456 gears, 350/205 without any power issues by the way I weigh 4300#  I will be converting to methonal for next season.

[old school truck dude]

Thats 3 votes for an 850

1050 dominator

i think that would be  a touch on the large side. google it there is a formula to find the right size carb
