Probably not what anyone would expect to see in this thread. My former 69 SJ, 428, T 400, D port iron heads, dirt track car. Balanced with TRW 12 to 1 domed slugs, reconditioned magnafluxed cast rods, deck squared block, .010 mains, .020 rods and indexed crankshaft, SD 80 PSI oil pump, circa late 1977-1980:
Not real pretty, or a show car, but there aren't many others GP oval track cars in photos. Original Verdoro green car. It was repainted white when I pulled it out of the wrecking yard (1977). After the 1980 race season it was returned to the same wrecking yard (Jay's Auto Wrecking, my sponsor), and crushed. After 2 1/2 years on the dirt track, it was used up, but in 1977 when I rescued it, it got 3 more years on life support as a race car before it was finally crushed. I've had the engine stored since 1980 just like it came out of the car. It is a 4 bolt main 428, but it's not original to that car, it came out of another 1969 SJ GP that was replaced at the Pontiac dealership I used to work at. I paid $75 for the disassembled, basket case engine in 1972.
The GP was to be replaced with a 1970 round port RA IV 455 GTO, but life got in the way and it was never completed. That engine was never assembled, I still have all the parts, and pieces ready to be assembled in my garage, and some in storage. New SD rods ported RA IV heads +.030 TRW dished pistons, balanced assembly, and a 2 bolt 455 block. I just turned 68 a couple weeks ago,
I probably should do something with it while I still can.
