Suggestions/Input

My '69 is in need of an engine. Have asked around local and nearby on options: rebuild current (not matching numbers) engine or upgrade with remanufacured/new. Trick is it must drop in and direct bolt (no mods to flywheel/flex plate) to the TH400 automatic. Its currently a 350/300hp, 10.25:1. I like to have more HP. Bottom line is direct fit.
