carb size for 512 stroker?

moparlover said

if you have 1.5 rockers that's a .548 intake/exhaust cam

with 512c.i. i'd say 850HP holley, no choke. mech secondaires.
you dont need 900 950 1000 dominiators etc.

performer rpm intake would be better.

you definitely need big mama headers. not the little 1 5/8". your 2" should be fine

at 9.5:1 you will be perfectly fine on street gas. a bigger cam is a waste unless you can get the comp ratio to 11:1

if you are looking for et's then you are better off putting $$$ into chassis

I disagree..... More valve lift = More air in the engine = More Fuel = More Power. No way getting around it.

His lift on that cam at the valve is probably real close to .500 after geometry Loss. If it were me I would be lifting that valve way into the .650 range after Geometry Loss.

Big engine with a small camshaft..... WHY Bother? May as well left it a 400 CI engine. The 400 CI engine would be better off with the Wimpy Stick.

Example: I have a 410 Small Block Stroker. Heads flow about 270 CFM @.600 Lift, Iron Heads, 9:1 Compression , Lift at my valve is .634 to suck in that air at that lift. Duration is smaller at .242 ....... His .500 lift at the valve is a big part of why it will never run like a raped ape. Change the cam it will be a whole different car.
