Re: Engine Upgrade on my 71 !
402 is internal balanced, 454 is external balanced. Do not drive/run the truck until you change out the flexplate for one the is for the 454. You did use the balancer off the 454....right? The balancer must be extrenally balanced on a 454 just like the flexplate. It can kill the crank and or bearing in the engine if you keep running it with the wrong flexplate.
