Default Re: 351 Cleveland Heads ?

it wasnt so much the power it was the fact the c wasnt a good design.if you didnt keep the oil changed the bottom end was gone at 70,000.the guides were gone earlier than that and they would crack across the exhaust seat.the tall block 351m was awful.having said that some did get service out of their clevelands.
