Understood.

With a BBF, you'll probably save 100 lbs between cast iron and aluminum heads, but don't get carried away with weight reduction on the engine as the engine sits considerably behind the front axle centerline.

As I mentioned earlier, your camshaft requirements will be more towards the "RV" side than the performance hot rod side of things. You will need excellent off-idle and low rpm throttle response/power.
