Okay, so a 454 has the same stroke as a 502 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Thanks to all your help I now know that the difference between a 454 and a 502 is the bore. The strokes for boh are 4.00" but the bore of a 454 is 4.25" and the bore of the 502 is 4.466". My latest question for you guys is will I have any problems boring out the 454 block to the same as bore as the 502? Will the new bore be to big that it will cut into the waterjacket? Any information you guys might have would be a great assest to me!

You Guys are Awesome
