Thanks for the reply guys. Ok, here we go. It's going in a 92 1500 series truck. It's single cab, short wheel base two wheel drive truck. I plan to drive it every day and go to my local 1/8th mile dragway every Sunday afternoon. I will run nitrous on it if I have to. I'm just looking for it to run low low 8s or high 7s. It has a 700R4 tranny which I would like to keep. The pistons are flat top with -5cc worth of valve reliefs cut in them. They have a lot of piston crown. I completely understand what you mean by "squish" so it won't be a problem getting the 0.040" gap your saying I need. The kit does have I-beam rods so I don't want to over power those. I plan to run NGK TR6 plugs and running it a little on the rich side doesn't bother me either. This will be the first chevy engine as well as carbed engine I've ever built so I'm lost as far as induction goes. What cam, intake and carb should I consider? I'm planning to run long tube headers with glass packs dumped for exhaust. I'm planning on running hydrolic flat tappet cam as well. Is this ok? Any suggestions and advise? Thanks again. You guys are a lot of help.
