Thread: Different Mark versions of 454.

Tweet

I'm just now beginning to get into automotive care. I'm wanting to rebuild a BBC to drag race. My question is about the different versions of the 454. What do I need to look at when buying a block? Are there big differences? Does each version need specific parts?

Welcome to CHR. Wiki has basic history that will get you started on the differences - Chevrolet Big-Block engine - Wikipedia, the free encyclopedia

There is much more to drag racing than just the motor. My best advice would be to purchase and read through a book such as this one to get an idea of the whole picture.....
Drag Racing 101: From Building Your First Race Car to Securing Sponsors: Ike Heckler Jr: 9781450514903: Amazon.com: Books

As far as what BBC to use, Gen VI. One-piece rear seal, 4-bolt mains and factory roller cam.
