Autopsy complete. Results
if this had happened twice who is putting your motor together. you are the mach. shop? if they are. Are they covering your cost? i have a mag head 360 and had the pushrods all the magazines said i needed for the build. when trial fitting we found out they were no where close. as others have said this has to be checked. if you change one thing it has a effect on soming else.now if you're paying someone to check all this do not let them play it off.the best shops i have found are guys who build motors for round track guys.go to the local track see who wins and find out who builds there motors even if its a chevy or ford.
