Stock 454 max rpm
This may be a little different than most of the "hot rod" tech questions but here goes. I have a 454cu in PCM in my boat & the manual says 4400 is the max rpm. There is one other model which has some differences. It has a 4 bolt main, different crank & heads, compression ration etc. It has a max rpm of 5200. My question is, will it be safe to run my 454 around 4700 rpm even though my model is the 4400 max? Am I seriously risking throwing a rod or busting my crank??
