Im affriad I made my bolt holes too big on my balancer so im thinking Ill need to buy a new one. I "think" my engine is internally balanced but ill double check when the balancer comes off.
My engine is a 454 with a stock crank and about 450 hp. It only goes up to about 6000 rpms so would a oem balancer work just fine? Also, i keep seeing in summit and stuff, Big block balancers and then it says 396 and 427 and then the 454's have their own. Does that mean the 427's wont work for my engine?

thanx
