i know its not a fbody but this form is really helpful

i have a 1990 s10 with a 350 from a 78 impala and 373 posi

the motor came with 170hp and about 250trq. so what i wanna know is what would i be looking at for hp/trq if i added 2.02 heads, .488 lift cam, rpm intake. and a 650 edelbrock.

so with that a TH350 and 373 posi. what do you think i wll be putting down. and if some one has any clue of a 1/4 mile time?

thanks alot guys. and i do still have my firebird. but this s10 is my project with my dad.

 

Insufficient information. The typical "2.02 heads" are 882 boat anchors. No different than what your '78 350 engine had, just bigger valves that don't help a lick with flow.

Give us casting #'s, that would be real information.

Or, just do Vortec heads.

Again, insufficient information. Need duration, LSA #'s.

Why?

 

the carb is what i got to work with.

i only know the lift of the cam b/c it came out of my dads vega.

the heads are 2.02 by 1.60 with 67cc chambers

 

As an automotive machinist who has done countless 350s, let me make some assumptions. One, the heads are World S/R Torquers, Not great, but you could see 375 HP. Reusing a cam, but in a different block, means buying new lifters. I assume it's a common, old-tech, generic, with 234 duration at fifty. And a lobe sep of 112. For what you propose to do, I'd say it'll turn 6000 rpm, and I'd advise starting with a 2400 stall torque converter.

 

i know the cams made by crane cams.

i know i need new lifters.

heads come back tomorrow so ill get the cast numbers.

so your saying around 300hp???

how do i find out what the cams lift,duration, and lope is? i have it in the garage so i can go look at it if needed.

thanks alot guys
