Re: Need mechanic recommendation
Another thing you might want to check is the cam timing. Often overlooked, it may need to be advanced or retarded. You are also fighting 91 octane gas and less while these engines were meant to be running on 102 and higher. With our old L78 car we had the timing backed off quite a bit so that the engine wasn't rattling. That takes away some power too.
