By the way, the folks that rag on us that want to build a 273 to stay correct/original and instead say just build a 318 are probably the same ones who get bent out of shape when someone has a Hemi Cuda with a 5.7 or a 392 saying that's not correct. That's my experience.
My suggestion: Tell someone how you did YOURSs, but don't tell them how to do THEIRS!
