I went with a 400 with alum heads/intake/water pump + denso alt
which weighs about the same as a stock all iron 360
(people who complain about an ABody being nose heavy with a bigblock are the ones using the iron heads)

aluminum heads and intake alone save you 65 pounds on a V8

if I was to build a small block I would definitely not use iron heads unless they were free.
beware ordering the AirWolf heads (supposedly the best small block heads right now) on moparts there are some huge whine threads because of 10-month backorders. i'd get edelbrock or something available rather than waiting 10 months
