To build an odd engine is aactually very very cool. If your on a beans and rice budget its best to stay mainstream- 318/360. But many of us are at the age where we have some money and want it done the way we could not afford in our younger years. I say build the Poly. And build it with the dual quad manifold and the stroker kit. Im a die hard mopar guy but a 354/392 Hemi or restored Polysphere makes me stop and investigate every time. (Along with the 409 chevy and Y block Ford)
