Scottj, if you don't mind telling, what was your bill for your dry-sump all aluminum 434 sb?

Do you have new block, heads, crank, or used block, heads crank?

I would think if you are going to build any all aluminum engine, with top quality parts, the total price would not be that different whether it be a sbc, bbc, sbf, bbf, ford fe, hemi, etc. Exception would be using a used LS1 chevy engine.

If you are going to put all that money in an all aluminum engine, for a 427 cobra, unless you get a great deal on a used engine, I would think that you would be best to buy Shelby's block as the basis, even though your options for other parts are limited. The engine would make more power than you would need anyways. I would think it would have the best resale value (desireable) should you ever wish to sale it, not that any other all-aluminum engine would not be desireable.
