help on heads selection
I'm having trouble selecting what set of heads I want for my .040 350 chevy. My shortblock will have race prepped rods with ARP bolts. Speed-Pro Hyper flat pistons. With a Scat cast steel crank. I don't know what gears I have, but their in a 72 truck. Lets say it has 3.42. I'm looking in a book right now that says I can get 487 76cc heads totally redone with 2.02/1.60, and harden exhaust seats for $500. I'm also looking at a set of World product 67cc straight plug head 2.02/1.60 screw in studs for $700. Will the World head hurt me. I mean it's a new casting verses a 25 year old casting. This motor has an high rise aluminum intake, and a 600 Holley. I'm going to use this intake, and carb due to lack of funds, so I have to go with these heads, or something close(Dart,Pro). Also I need help with cam selection. I've used a 268/454, 270/470, 272/4??, 280/480, and 292/501 comp cams before. I'm not up on rpm ranges of these cams, but I'm lookig at stall converters right now. One is a 1,600-2,200, and the other is 2,200-2,800. Can someone steer me in the right direction on Heads, Cam, and Converter. This is a 1972 Chevy long wheel base pick up. I would love to run mid 13's, or maybe high 12's. Keep in mind after I find out what gears are there, I can change them in time. Someone might could give me an idea what gears could be in it. 1972 truck, 350 engine. Not really worried about gas mileage, but I do want it streetable, 93 octane, and somewhere between 9.5- 10.5 compression.
