blown 350

my opinion, 9:1 is too high for any blower,8.5 min,7 and change better.Don't know about water inj.but ya might need it for detonation.you did'nt mention lift,not much needed w/"stuffing".

I can tell you that I have a 9.7:1 350 with a 142 running 6 psi of boost and it runs great. The solid lifter cam is 236/236@.050. It's also a two bolt main with the factory cast crank and I'm not afraid to take it to 6000 rpm. I've had the blower on it for almost two years now without any problems.

There is one catch though. It will run on straight 92 octane without any issues if I'm just cruising lightly but if I drive it harder (which I usually do) I have to mix about 20% 114 in with 80% 92.
