I have a 350 small block 010 block casting bottom end is stock i have 882 heads but they were leaking oil so i figure ill just replace the heads with better ones i also have a HEI setup 600CFM Carter carb & Long tube headers

I was thinking of running either camel hump 202 heads or vortec heads im looking to make around 400HP so if you can help me out with heads and cam selection that would be great

Im looking to build this motor for around 1,000

Either way the heads are most likely going to need dual valve springs so im ready for that...


This motor will be hooked up to a TCI turbo 400 transmission and a 3,000 conveter & 3.73 gears

If this is a street car go with a set of Vortec heads, you will thank yourself later.

what would need to be done to the vortec heads to run a bigger cam because stock valve springs only hold to 480 lift i think and how much is it going to cost me ?

It is a good idea to go with the Vortec heads. I would upgrade the valve springs for up to 0.60" lift since the stock springs can't go above 0.47" or so they say.

I'd go with a Edelbrock air-gap intake for the vortec heads for an intake.

yeah i had planned on the rpm air gap no matter what heads i used ...

how much can i find a set of vortec heads for and where i looked on craigslist cant find any for less then like 500 dollars !?


and what size cam do you think i should run i was thinking of a comp 244 duration and 501 lift should i go bigger?


how much power do you think this will make and what 1/4 mile time its a 1966 el camino posi 3.73 gears turbo 400 3000 converter suspension is all set for street/strip

find a stock Vortec 5.7 long block and stab a cam in it with some beehive springs....

LoStOCeAnZ63

I already have a short block paint matched to the car just need to figure out what cam to run and i need to find a set of vortec heads and have the valve springs changed

LoStOCeAnZ63

does anyone have a idea of what came i should use to make the best power and to still be able to drive on the street? im trying to make as close to 400hp as possible vortec heads dual valve springs rpm air gap manifolt 3000 convter turbo 400 3.73 gears long tube headers 600fmc carb hei setup

was thinking 501/501 comp cam??

use gm LS6 valve springs or some Comp 918 beehive springs. use the lunati 231/237 duration Voodoo. cam.
