Actually a ford flatty weighs in at a mere 460lbs, where as a chevy small block is roughly 550lbs.

The dohc fiat motor is a cast iron block with an aluminum head, ive got no idea what it weighs, but the ford flatty cant be that much heavier.

I wish I had an aluminum gm 215, unfortunately its a flatty ive got sitting in the garage, it runs but is real tired.

I just dont want to jump into another project here that I cant finnish.
