Google “mopar performance A8” this will get you to the “available now” aluminum small block that mp sells for sprint cars. Many special parts are needed. Or contact Ernie Elliot race engines for thier own aluminum casting to be used with P7 heads. If you have money you can get a new aluminum small block.
I think I'll consider an aluminum block for the 440 only, it's just too expensive and more difficult for the small block.
