Supercharging is the way. Been running boost in my c10 since july, and not one problem. It starts fine when cold in the morning. Fine in traffic to work. Im running 9+ lbs of boost, and shifting at 5200. Have added over 10k miles since july. Mileage didnt change after stuffing. It is a 305, 906 heads, and performer cam. You would never believe it.
Much misinformation on blown engines. They want to scare you away, because it is too easy to make big power. Stock small blocks can easily handle 6psi.
I have a couple horror stories, but they were shifting at higher rpm. Not considering normal limits.
