Absolutely, if you can get the parts.

parts list provided, along with sources, at the end of the file.

Yep, good luck with that A consumer is not going to be able to get these parts in the near future. You don't want to know the hell and months of time we went through to get 4 pieces for the Turbo car and Bonneville Transmissions. Dealing with GM is not a pretty picture at this point in time.

ah, such is life. either way, it'* nice to know how GM does it though. I know i've heard people ask countless times how they got the 65 to handle the HP from the racing setup...
