Hello guys,
I have been working hard so it has been a few weeks since I was on the page. A friend of mine has a question that I cannot answer so I thought of you all. He has a 454 block that is supposed to be a "high nickel" block. It is marked Hi Perf pass but Mortec only shows the block as a 454 with some CE blocks four bolt. The block is a two bolt. How can we tell if the block is "high nickel" and even if there is such a thing. Block #3999289,HI PER F9 ON REAR,FRONT HI PER PASS E 10.
He also bought a forged crank that the numbers show to be a 396 piece. They told him that a 396 crank would work on a 454. That would mean that all the BBCs have the same stroke? Or is there a rod length difference?
