hi guys, new to the board here, been here less than a month. need your opinion on a engine combo i have in mind, here goes...
350 small block
stock bore
steel crank
.125 domed pistons
summit 214/224 cam with1.6 roller rockers
edelbrock performer rpm heads
edlebrock performer intake(hood clearence requires this intake)
edelbrock performer 750 carb(650 holley dp is also available)
mallory hei with accel spiral core wires

any opinion will be greatly appreciated, i already have all of these parts
and a few extra (hooker super comp headers and a edelbrock victor jr
intake

heads are 70cc with .030 taken off

car is 80 trans am se and just for fun, light street/strip
thanks ahead of time for all who respond

Ditch the domed pistons and it'll be a groovy idea for an engine.

Just a couple of things. As far as the pistons go, I think it might depend on how many cc's a .125 dome displace. I know that usually flat top pistons with dual valve reliefs in a 350 with 64cc heads is around 10:1. If you use 70cc heads, that will drop it to around 9.5:1 with flat top pistons. Having aluminum heads allows you to run around 10.5:1 easily on pump gas. If a .125 dome takes youto 10.5:1, you may want it. I am not sure how much of a difference that dome makes, but that is just something to look into. Also, I would use the 650 carb.

Good luck

i have a 214/224 dur.@ .050,.443/.465 with 1.6 roller rockers it changes to .472/.496.it sounds great and runs great but i would think that with the domed pistons you're using that you would want something with more dur. around 280* so it will bleed some of the compression off.my last 406 had 10.5-1 with iron heads and ran fine on premium but with the price of gas are you sure you want to do that?i'm just now building a new 406 with9.4-9.8-1 to try and take advantage of 87 octane and still get good performance.

the engine was together in a drag car with absolutely 0 passes on it.
i changed cams, head gasket thickness, and carbs(twice)
original carb was holley 950hp, now running an edelbrock 750
holley 650 just didn't have the punch of the edelbrock

car is 80 trans am turbo se, sans turbo, b&m 2500 converter with a 3.23 gear
it runs out very well, but i think it needs a timing controller to keep my detonation in check. its not bad if i keep it conservative and run real good gas with octane booster, 110 sunoco,(lmao)

If you are going to be running high compression anyway, I would go with a bigger cam, something in the 235 @ .050 range at least. Also a gear change would make a big difference.
