I have almost all of the parts required (many new, some used, some newly machined, for a GT6 engine. The set includes a short block with cylinders bored out 10 thou, crankshaft machined to accept new main bearings, head with valve seats machined. I have twin carbs, intake and exhaust manifolds, aluminum rocker cover, camshaft, distributor, etc etc. I have new pistons and rings. Many other parts needed to build a complete engine.
I also have a second short block and head.
If you are seriously interested, email me and I'll send you photos.
