cast iron heads vs aluminum for stroked 340

OK so I just gotta say this;
My 360 with its little 232* cam, on city streets, lights the 295s up in 2nd at up to 50mph (4500rpm), without clutching it.My car weighs 3650,me in it. And I'm at 900ish elev. Granted my chassis sucks(60 fts at about 2.0 ). This S-clone goes 93 in the 1/8th(at 3450lbs) and spinning most of the way.It scares a lot of folks.

So heres the rub;
I absolutely cannot imagine 550/550 in an early A.

If I were to go stroker, in my 2nd gen Barracuda,I would just put my stock Edelbrock top-end on it,and my little 232* cam in it, and see what happens. To my way of thinking,Numbers dont mean that much on the street,at this level, except maybe for bragging rights. Its like going hunting with a cannon; just how dead do you want that animal?

Maybe I'm just not getting it.Oh well.......................... Never-the-less, enjoy!
