stock heads and supercharger
I just broke a spring and dropped a valve. Needless to say, I am sure I did quite a bit of damage to the head, piston, etc..etc... I made 440 to the wheels with the mods in my sig. This setup wasn't too terribly bad to drive on the street buuuut...I would like to 1: get to 500-550 rwhp and 2: behave a bit better on the street. I will probably get a fresh short block and am looking at doing 383. I know I am probably going to have to replace at least one head so my question is: if I buy a set of used stock unported heads, can I get to my goal with supercharging/mild cam?

I had a 383 with stock heads that had the casting flash cleaned up and a small cam. 12psi non intercooled got me to 10.6 at 138 in ideal conditions. I think it is doable if your tune and combo are spot on.

I would say drivability depends on the size of the cam and the quality of the tune. I have not had problems (knock on wood) with a stock cooling system, electric water pump and 160 Tstat in 16 years.

Drivability really depends a lot on the tune. My old 383/YSi setup made just shy of 800 whp and drove fine with a 234/250 duration cam. The new 408 drives even better with a 235/247 cam and a single plane. No FI on it yet as they're sitting on my closet floor.
Cooling system on the 383 was a stood up aluminum radiator with derale fans. Same setup on the 408 but I'll probably change to a double pass radiator to eliminate the hose on the driver side.
