Will the current cranks and heads work with a 4.80" spacing?

If so, why not do it?

If not, you are looking for alot more than our community can support, imo.

Again, in my opinion, if you step up to a "spread bore" Aftermarket Block design, you will most likely be using a Custom Crankshaft anyway. Moldex can make a 4.8" Bore Spacing Billet Crankshaft just as easily as a 4.625" Bore Spacing Billet Crankshaft.
