Small block to big block convert questions..

Lets see, aluminum intake, water pump and housing, and heads. Toss some headers on and now you weigh close to an all iron small block.

Right, but who wants an all iron small block at this point? Making both light is a cheaper way to go faster, along with the other benefits of making more power, cooling effect. etc etc. Aluminum parts would be on both
Im going monster small block this go around. Made up my mind lastnight after see streetwize build 440" sb. Its on moparts and youtube, pretty slick, pump gas and makes killer power. plus looks correct in my car... kinda :)
