Thanks for the welcome chevy fleetside. I have found some sites that offer a lot of parts for these trucks, here is one of them
http://www.americanclassic.com/asp/dyncatv2.asp I am also going to be running a 700R4 with a 350 chevy. It was the last engine I built before I closed my doors. It is 30 over with flat top pistons, a zz4 roller cam and airgap intake with a 750 holley. I wasnt sure were it was going to end up when I built it, but have decided on putting it in this truck. I am getting the tranny back today from having it converted from electric speedo to gear drive, and I am ready to drop it in. Excitement is building!
