V8 conversion

A 318 Poly? Why would you want one of those? They were an OK engine, and it would physically bolt in, but parts are hard to find and they are way heavy. What would you use for exhaust manifolds? The selection of performance parts is almost zero as well. Then again there are guys who will spend twice the cost of a built 360 to install a first generation Hemi...

I believe the poly's all had steel cranks however, which might be worth something to a 340 guy.
