Max Power w/ Stock Unported Heads?
Does anyone have any idea on how much power would be feasible on a stock unported head car with a built bottom end?

My LT1 put down 480 RWHP and 514 RWTQ on a Mustang Dyno with an S-Trim set up for 12 psi. Stock heads (besides valve springs), MAC shorty headers, stock TB, and 42 lb injectors. Pretty raw tune, also.

I was shooting for 550-600hp and it seems like it may be realistic from the above posts.

with that turbo i dont see a problem making over 700rwhp,as long as your buttom end can hold up and whoever is tunning knows what they are doing. put it this way i think you can make plenty of power on stock heads, the question is can you keep the motor toghether, if you can you should have no issues.

yeah, im shooting for 700 rwhp on stock heads, and throttle body...alot of people like to tell me that im completely wrong nd its impossible, but i feel that with forced induction, porting everything is somewhat unnecessary as its getting rammed in faster than it can suck it in anyway. if I can tune my car for 18 psi, whats the point of porting everything only to then make 16 psi and slow down the intake velocity.

I would have to say at least 1k(flywheel, with appropriate turbo)
This guy made 1k with 882's

So, Leadfoots heads are unported. If they were ported or cleaned up a bit they would be less of a restriction. If there is less restriction they will flow better and show less boost pressure.
Does that mean Leadfoot can add more boost?
If his goal was 8# (example) and if the heads were less of a restriction they would drop to 7#, could he add another 1# to get back to his target boost?
