    2002 BBC 496 Engine

    I just bought one of the GM 8 ltr Motors hoping I could make a 502 out of it only to find its a tall deck..Are there anything you can do with these?

    Since you have to have a new crank anyway I'd go ahead and put a 4 1/4 stroke crank in it, bore it to 4.5 and make it a 548.

    Wayne~DONT Think Its Got a 7"Rod,its just that the Pin Height is adjusted!

    Seems My Last 1 was a 4.50 Str.,6.700 Rod,1.240 Pin?That will make you a NICE COMBO!!!
