Building a mild 440

ummm.... it takes nowhere near 450 hp to run high 12's in a A-body. My Duster runs high 12's with 3.23's, stock converter, and a real mild 360 (no lumpity lump lump..lol)
Well I really don’t plan to race it often but need it mainly for cruise and car shows , some burn outs , possible match races against my blow hard chev friends,,,,, it just has to be able to back it up
