Want To Make at Least a 12-13 sec car My friend has a 3970010 Block and wants to put it in a G body.
He also wants to go roller cam & rockers. He wants it to be a weekend street strip car. We are looking for opinions on a good combo of Heads, Cam, Intake
Stall, Gears Ect. I think he is going with a 350 or 400 tranny. NO NITROUS.
He has a budget of $5-6k on drive train.

what the hell is the block?? 350?? and what year is a G-body?
also you will have to do a bit more research before you go out and build a 12 sec car! but w/ 5K its deff doable!

3970010 is a 350.
its going to be either a 81 malibu 85 cutlass or 85 regal.
does it really matter what G-body? there all around the same weight.

383ci with vortecs and about 10.8:1 and a comp xs282 cam= 244/252 and .520"/.540" lift. thats proven to run 11.60's in a malibu at 114mph on drag radials with 3.42 gears with a th350 and 4000 stall. Got 12-13 mpg. Had Super Victor intake, 750 dp, and weighed 3500 pounds. Only difference was his was a 413ci and about 11.2:1 compression.
This 383ci combo could run at least 12.0hs.

Not much money, but as said, possible. Stroker is great idea, torque is good. 350 trans, with the correct combo of heads,
cam & compression you're there. Just not a fan of doing it cheap, good luck.

nevar! i love G Bodies. I have an 85 Monte SS back home with a little 358 in it with some world product heads (pretty heavily worked)and a .535/.515 cam(IIRC). That combo with a RPM air gap and a demon 750 was capable of 12's on under 9.5 to 1 compression (setup for a blower)

Since he has the block and intends on keeping it, build a 383 with forged pistons and a cast crank (like a scat 9000 or similar). Build it for 10.5:1 compression. Short block should not cost more than $1,500 if you do it yourself with standards rings and cheap forged pistons. The price also assumes that you don't get raped by the machine shop.
Throw in a set of aluminum brodix IK200s ($1,100 for as cast, $1,400 for CNC machined). A mild solid roller valvetrain with about 290 degrees duration, and .600 lift (comparable price to a hydraulic roller setup when retro-fitting, but with more power and valvetrain stability) will set you back about $1,000 for cam, lifters, springs, pushrods and timing set. Top it off with a victor jr single plane intake and 750cfm mechanical secondary carb(under $300 if you buy used).
Some cheap 1-7/8" painted long tube headers will do fine. 2.5" dual exhaust with whatever muffler floats your boat. X pipes and H pipes add a bit more power, but if it pushes your budget too far, you won't miss not having them.
He can run a th400 with a kit and be fine, but if that car has a small 10-bolt rear he should be careful with it. Don't skimp on the converter...a 10 inch 3000rpm minimum for this setup. If it's an 8.5 (too tired to check to see what that car had), then a 3.90 or 4.11 gear will do if it won't see the highway much. Invest in some slicks or a set of drag radials and if you don't hit low 11s then I'd be surprised.
