Stock Vortec head, 207@.050 LT1 cam, Edelbrock Performer manifold combo. I think the biggest thing making it feel lazy was the steel wheels. Borrowed a set of aluminums once and I was amazed at the difference.

Got the new truck running TBI on the 7427 and drove it in the garage. Was getting excited to start playing with it...and then the wife found a truck I couldn't pass up. So this one will be getting sold as-is cause I have too much other stuff to do. Kinda disappointed because it would have been cool to do this MPFI conversion finally. But I ended up getting a Vortec 8.1/ZF6 6spd 2500HD for less than this 1500 was going to cost me. So I had to think with my head, not my heart...
