    I'm no motor expert, but my buddy is looking at buying a 72 blazer that has been built by a mechanic. He said the motor is a 454 block with a mild cam, and a 396 crank. Does that sound reasonable?

    he also said that made the motor a 426? I don't know sh!t about cookin', any thoughts?

    my buddy is a potential new member for the board!- more newbies! (like me)

    As you can see here , the "Factory" simply used a 396 stroke crank in making the 427 . Then when they went bigger they used the 427 block and got a longer stroke and made a 454 .

    So yes that 454 would be a 427 if they destroked it by using a 396 crank /forums/images/graemlins/thumb.gif

    BTW , motors with shorter strokes , when equipped with a good flowing heads , induction , and solid bottom end and valvetrain will rev higher ( drag cars and mud racers ) /forums/images/graemlins/waytogo.gif
