Re: Turn 396 into 427?
OR for about the same money, start with a 454 P/U core block and bore it out to say a.060" over, then use your rotating assembly to make about a 440" motor!
Or boring it an 1/8th over will make it right at a 452" motor!!
But for all this trouble, I would save the 396 IF it is stock and make a 496" motor!! Then you can make BIG easy power!!
