Deduct for aluminum heads and intakes on both if attempting an apples to apples comparison.

with an aluminum block even better. I replaced my Roush iron block 351/427 with a Pond Aluminum FE block, alum. heads, intake, manifold and water pump with a 15 lb alum fly wheel. The things cracks just like a small block when you snap the throttle. Have to readjust the front ride height as the front end not sits higher with the lighter engine.
