My iroc weighs app.3400lbs. I would like to know a good head ,cam,intake +carb combo to get me in the 12's.I do not want to rebuild the bottom end as I one day plan on a different engine trans.combo. I just want to hammer this one for now .I have a tci 700r4 w/2200 stall and a 2.77 posi.anyone build anything like this?any help is greatly appreciated

 

How extreme do you want to go?

 

I would like to keep it streetable enough to safely cruise on the weekends and hit the track as much as i can .Also i,m hoping to limit it to the top end for now as i am on somewhat of a budget.I know the bottom end will leave me eventually .this is my first project so i,d like to learn on this block.also i,d like to keep it 93 octane.I dont ask for much

 

EFI or carbed ?

There quite a few options for you to do this weither EFI or not .

try searching for 12 seconds N/A

 

First thing i'd do is go with a bigger stall. 2200 is too low for what you want to do. Step up to a 3000+. Gears are fine. I ran 13.6 with my 2.73's and 3000 stall.

As for heads.. I like trick flow's but there are so many to choose from. 220/230 duration cam, demon carb, and DR's should get you in the 12's no problem.

 

I am looking at carbed for budget and no prom tuning needed . nos could be a last resort but i,d like to try for n/a 1st

 

thanks sleeper that helps alot. I could probably call the head company w/ cam specs for their suggestions.should i go hyd. roller .what headers would you recommend?750cfm demon?

 

AFR 195's, Comps 236/242 grind, Air Gap intake, 650 DP, 3200 stall, 3.73's, 28" tires, decent headers/exhaust setup.

 

vortec heads, 3000-3500 stall, 3.73 gears with 26" slick, or 4.10 gears with 28" slick, XE 274 cam, and 750 holley DP with a air-gap performer RPM intake will get you 12s for sure, maybe high 11s. This is the cheapest combo out there for solid 12s on a budget.

 

This guy has a factory roller cam block, so......
Comp xr282hr cam/AFR 195's/rpm intake/holley 750

 

Thats about the same combo I will be running. I have the comp xr282hr cam/AFR 190's/ Holley 750 vs. Im just not sure on the intake. Oh yeah, I will be running a 2800-3000 stall with a th350, 3.73 gears, and 26" tall tires. I hope to have this combo at the track this spring.

Oh yeah, I am running Hedman LT's with dual 2 1/2 exhaust with dynomax bullets.

 

if he only wants to run 12s then AFR heads are going to be a waste of money. He could save the $900 from them and spend it elsewhere. If his goal was 11s then I would push the AFRs or Dart or Brodix, etc. But 12s aren't that hard to break into with a cheaper combo.

 

I agree, but we all know that one will only be happy with a 12 sec 350 for so long. The $1200 AFR's will still have plenty of life left in them when he decides to build a 383 or 400.

 

thanks to all.this is my 1st project and i'm glad i found this site.i just started racing my iroc and got hooked on the 1st pass.my nephew is 16 now and wants to drive at the track.we've already cut .6 off 1/4 times w/basics.best of 14.17@96 on street tires.once he is comfy w/that .i'm going to build on this block as much as i can till it goes.then who knows 434?thanks again to all you guys are great.
