cast iron heads vs aluminum for stroked 340

autox - agreed... I guess beefy could be translated into beastly or nasty.

And the car has no vacuum accessories at all. It's caged, most things are not in it anymore, etc.

It's actually a 66 valiant signet, which was a pain the you know what to fit a SB into to begin with. It was originally a 225.

No frills, big HP/TQ, and maybe very accurately "unreasonably streetable". No turbo's or blowers either. Definitely looking for the under-stated wow factor...
