It's a 402 with the stock iron heads with around 105cc chambers if I remember correctly. The pistons have a slight dome, I figure comp. will be around 9.5 maybe 10:1. 3.76 stroke/4.128 bore, the cam is a single pattern 305 adv, 255 @.050.
The cam is set up more for the upper range than I'd like, but I'm gonna see how I like it. I still haven't gotten a tranny, but I think I'm gonna get a new one that I know will be strong enough. I want to get a rear soon so I can keep busy this winter setting up the rear susp. I figure if I find a good doner vehicle I can get a rear for fairly cheap and buy it right away.
