My new street rod is a Chevy powered Mercedes. Been out of engine building for a few years so I relied on tech info from my local speed shop. I think the specs are to soft for what I want to do, so here goes : 3,700 # car, 700R4 trans, vette 3:73 rear, 27.5" tall tires. Now, the good stuff, SBC 383c.i. w/ 5.7 rods, edlebrock alum heads, performer 170cc runners, 72cc, 1.60 / 2.02 valves, Air Gap dual plane intake, Race Demon 650, flat top pistons, 10:1, 1 5/8" headers into long collector w/ crossover and 2 1/4" pipes. I saved the cam for last cause its not in yet. The car will be a street rod that will only see the strip once or twice. For street use I want all low end torque, even if I`m done by 5,500. The cam can be hyd. or solid roller, and I`m guessin about 220@50 / 525 lift and 106 centerline for rumpity rump. I want a rocket street toy but I think that the heads might be too lite. Short block is done and I have the other parts, less cam. I`m willing to change or modify if needed . Whats the right answer for my setup? I`ve got pics of the engine and car if needed.
