Main bearings small block chevy,rocket block
Hi I have a 427 olds rocket block chevy engine that keeps tearing up #2& 4 main bearings after 2 burnouts. I have had the block line honed,a callies crank at first, had it turn twice due to bearing failure & just put a eagle crank in it with the same results. New four stage drysump oil pump & line also.All the rest of the bearings are ok. Any ideas would be great.
