advice on an old school truck
#11
Those trucks are heavy and have a very poor aero design. You can get into the 12's easy with a good strong motor and about 150 of spray. I just built a 383 with a carb that dyno'ed in at 390 horse 440 TQ and that is with stock vortech heads. If you take your time match up your parts you can make it fast but you are fighting an up hill battle make sure that you do as much weight reduction as you can.

I'm pretty sure those trucks are lighter than the 99-06 models, so it should be easier to make fast than our trucks. Anyway, I would use the 350 block to build a 383. Shoot for 9.5:1 - 10:1 compression, get a decent set of heads with moderate sized intake runners like Canfield 195s/AFR 195s/Trick Flows, a roller cam (call his cam company of choice and have them grind something for his application), top it with a performer RPM intake and a mechanical secondary 750CFM carb and throw in some 1.75" headers. Back it with a built TH350 or 700R4 with at least a 2800 stall and some 4.10s. Throw in some sticky tires and I bet he runs 12s.

i know a little about the subject i just put a 383 in my 70 longbed chevy. havent gotten it to run yet but hopefully itllmove. i went .060 over hypereutectic pistons. bout 10:1 whole new bottom end. dart heads 2.02/1.60 with a 200cc intake runner. 64 cc combustion chamber. lunati voodoo cam 219/227 .468/.489 112lsa. performer rpm with edelbrock 600 (probably gonna be too small). hasnt been fired yet still waiting to purchase new headers to fit the angle plug heads. oh yeah i put a new accell hei, super coil, tr55 plugs, and accell wires. stock th350 with a 2500 stall and a shift kit. curretly 3.08 gears gonna switch up to 4.11s with some sticky tires hopefully ill be ableto push it low 13s.
naturally aspirated makes your situation a little more difficult. check out the kits sold through summit and jegs to punch a stock 350 up to 400 horses or so and choose a little better parts than that
