Let’s assume the heads flow 275 cfm@28” ( about average for out of the box ) at .550” lift.
That’s enough to make a super easy 525 Hp through a gasket matched T2 or the Performer rpm with your CID while having excellent drivability with 3.5 series rear gears.
Now let’s say your shooting for 600 Hp.
Now the heads will need to be ported some so that you have between 290 and 300 cfm available at the lift your cam is providing.
At this point also the Performer rpm should get left behind and the T2 ported some besides the gasket match and a 1” blended carb spacer used.
So now the question is do you have the hood clearance for that while running a decent air cleaner?
