I know its been a while but I haven't quit. Things have just taken much longer than expected.
I ended up having the motor pretty much completely rebuilt. To refresh the block and crank are a 75 455 from a grandville wagon. The crank was turned .010 as well as the block being bored .030. All pontiac loaned me a torque plate for the final honing. The mains were were also studded and align honed.
The pistons are the newer keith black forgings with the 15cc dish and rods are tomahawks from pacific performance racing.
The heads are 4x 4h's with screw in studs, 2.11/1.66 valves, crower 68404 springs, and some minor port work by me, mainly just gasket matching and some bowl work. Although I think they may have been surfaced before, after a cleanup cut the heads were right a 96 cc's. With the pistons .010 in the hole, and 1016 head gaskets I figured that I will have right around an 8.7:1 compression ratio. Probably a bit high for boost, but I have a huge intercooler and an MSD 6btm to pull out timing.
The cam is a solid with 251 degrees of duration on the intake and 263 degrees of duration on the exhaust at .050. Lift is .530 intake .556 exhaust, a bit more with the 1.52 rockers I will be running. The cam was degreed in per the cam card, it came in at 107 degrees instead of the 108 degrees recommended, I figured I would try it here first before I changed it.
The intake is a tomahawk from PPR, I still have to gasket match it and cut off the crossover, I also have valve cover spacers on the way so the polylocks clear the covers. Other than that and dialing in the bellhousing the motor is pretty much ready to go in. I'll try and get some pics of the engine bay in the car next week.
