Last night someone suggested useing a 360 crank turned down. I haven't had time to crunch the numbers but I might be able to use stock 273 2bbl pistons.

However one thing I do want to do is make something every one can copy if it works out, thats why the small block, mabey a 318 would be better for this purpose cuz every one has one. I don't want to run a slant becuse there is no closed chamber heads and I would have to swap a bunch of stuff to run it in my car, like exhauset and motor mounts.
