Question 347 Question

I was talking to an engine builder the other day about stroking my 302 to 347....the first thing he said was "What they don't tell ya about those stroker kits is that they make the mains come loose." He said a 331 stroker would work ok though because "there not much bigger than a 302 crank". I didn't think to ask him....would a main support girdle prevent this from happening?

Haven't heard that one before. I've ran one before in an IMCA style modified and it was durable and performed well. Cheap stuff too, stock block and cast crank.

Never heard the mains loosening up before, maybe running some crazy hp with forced induction, but if you are going that far you are using a A4 block and studs
