there are lots of parts out there for them yet you just have to pay a little more. the biggest price difference was the main brgs at $110.00 a set and the pistons were $300.00 . not to bad considering. rod brgs and bolts are same as SBC and oil pump BBC. i have spent $1500 on the bottom with boring pistons, recon rods balance and engine kit. probobly have a little over 2K in it when the top is done. still not to bad for a rare bird.
