hi again, once again i need some help and i know someone on this forum has the answers. i'm working on a 1951 chevy styleline deluxe, 216, 3spd. in the process of getting the engine running correctly, i found a couple of push rods that are a bit bent. it does not seem to be a problem with first start and running it in the driveway but, as long as i'm in there i thought i would change out the bent rods. now getting the replacement rods is not a problem. everyone seems to have the "correct" one but the trouble is the correct ones, according to the various vendors i have went to, are different sizes than what i have. so....what is the correct length? can it run with the wrong size? i also have a problem getting oil to the rockers. i have cleaned everything from oil pan to the rockers including the feed tube but i still get very little oil up top. granted the engine has only ram at low RPMs in the driveway but could the pushrods be wrong and be a factor? thanks again.
