i'm just about done with my 350 build, waiting for the upper dipstick tube to come from GM. it's a 71 block, with 70 #16 heads. Block was bored .030, decked .010, had to have cylinder sleeved, but the place that did all the machine work also builds a lot of diesel motors, so they knew what they were doing when it came to sleeves, and they also knew about building pontiacs. anyway, since i found the block in a backyard near a coal mine, had it magnafluxed, came back just fine, except for the #1 cylinder, which couldn't be bored because of sever rust. Heads are like i said 1970 #16 castings, rebuilt before i got them. stock valve sizes, but you can't go too big on a 350 because of shrouding. pistons do have reliefs cut in them. stock bottom end save for a .010-.010 cut on the main and rod bearings. 66 389 4bbl cast iron intake, holley 750 4160 carb(vac secondaries) Cam is a melling grind, 067. (350 4spd grind) torque converter is 2400rpm stall, rear is a 3.73 lsd out of a Monte Carlo aerocoupe. 68 exhaust manifolds with the flapper removed. Should be a pretty quick and reliable set-up for my 79 Grand Prix.
