There are Millions of good used 305 SBC engines in old rusted out impallas, Monte's. Camaros. trucks,
in peoples yards. So if say you do happen to get a carried wawy on boost or fubar the tune (jetting/timing) and smoke the
305. it (the basic 305 short block) can be replaced for as little as FREE+ gaskets and time.
You will never run out of a good source of perfectly good used 305's to try and kill.
You will find that boost will not kill the motor. But detonation will.
Be prepared to go very fast for very reasonable cost. If thats too much for you, stay on the porch.
