engine combo

ok what do think this will make at flywheel

79' 350 (.030 over)
Vortec heads
1.5 rockers self aligning.
Edelbrock 650carb
Intake.....? take off zz4? need suggestions
comp cam xe262H .462I .469E Hydraulic flat
flat top pistons around 10 to 1..or so
cast crank....
Full exhaust

im still deciding on intake and exhaust. so any ideas would be nice. or even a different cam. but it cant be really expensive lol.
I also have some lt4 valve springs that i may put on so i could go with a bigger cam....not sure. i want a car that has decent vaccum at idle. thanx

Try a 750 CFM carb and an XE268 instead of an XE262, you'll still have lots of vacuum.

The XE268 would probably work with stock springs, but I'd have to check to make sure.
