Sean, The pistons can go from 11-1 down to 9 -1 if used with 76 cc heads (I think,it may be 73cc)I'd have to look back in my old files.
What I started out to do about 9-10 years ago was to build a 1970 LT-1 350/370hp replica motor. Over the years I had gathered up almost all the internal parts and was told that the pistons would match the factory combo with the right heads. They were and still hard to find so the project went on the back burner for many years.
The oringal GM manifold and carb were sold and the exhust manifolds stole. Still have the factory soild lifter cam w/lifters in the GM tube and lifter boxes.
The bottom end is finished so I am now just look to put togrther a mid-range hp engine.
This engine project was put on hold about 10 years,but have'nt we all that love cars an trucks done something like that for some reason.
