400 builds-anybody?? NON STROKER!

Thanks all. This helps. Got 2/440’s and 2/400’s to decide which to put in an A body. Makes me think more. Not interested in a 440source stroker.

Consider doing a 400 with aftermarket pistons (valve reliefs!) like KB and 75cc aluminum heads. I think Edelbrock E-Streets are available in 84 or 75cc out of the box or you can easily mill 84's to 75cc.
