I'm rebuilding a stock 292 for my Chevy 1/2 ton 4x4 truck. This is not a hot rod,I'm replacing a worn out 250 with a 292.
I have access to a new set of Sealed Power 980P pistons in the correct size for very little money. I believe the 980P is the propane pistons?
Using a stock cam will the engine be detonation prone on regular gas ? If it won't detonate on 89 octane that'll be ok....Anyone have real world experience on this? thanks
