I am continuing this subject from another thread that kinda took off in a different direction. I am looking at swapping the 283 out of my 62' it has a TH350, 3000 stall(22-2400 with the 283) & 308 gears. I have a 355 short block with flattop double valve relief pistons & its waiting for a cam & set of heads. I would use the Performer RPM intake off the 283. I have been looking at a 280 or 286H Comp cams & maybe some S/R World heads with 67cc chamber & 170cc runners with 2.02 &1.60 valves. Is this a good combo or are there some original castings that would work good. What about cams? I want a strong running street car that I am not afraid to to drive anytime I want.
