well i have a 94 camaro A4 and looking to do some upgrades for the winter.
my set up is longtube headers, 4.10 gears rebuilt 4l60E with all the inside upgrades, 3200 Fti stall, cold air intake with a pcmforless tune.

mods i want done is
-58mm throttle body
-ported intake
-full exhaust no cat
- 503 cam, new rocker arms, push-rods, springs
where can i buy the 7/16 push rods or can i use a different type of 5/16 push rods...i really don't know nothing but im learning everyday...looking to get about 350-390rwhp

 

You dont really need the 58mm tb and ported intake. The stock intake and tb will work fine for ur power. Save that $ for better valve train. Id buy comp pro mag 7/16 rockers, 7/16 rocker studs, and some guide plates. Far as pushrods just pick up a set of chromoly 5/16 pushrods. Ur goals of 350 to 390 is a bit high for cam only auto. Ur power with those mods should be round 330ish. Good luck with ur future mods. Car will be lot of fun with cam swap.

 

thanks 330rwhp sounds good you don't think I need springs

 

Yea u diff need some good springs. Also a good dyno tune. Id also do A new timing chain.

 

Yeah...you will be nowhere near 350-390. With full emissions equipment on my LT1 with very similar upgrades I have 315 RWHP. Without all the emissions BS you'll be around 330. Plenty of power to get in trouble with. Good luck with the mods!
