I know you seem mainly interested in a small block, but I've noticed that there happens to be a couple of brand new still-crated LS-7 454's on E-bay. Just ask anyone who's ever had one of these. They absolutely fly. A friend had one untouched in a '68 Camaro, Turbo 400, 12 bolt w/3.73's running 11.30's. Don't forget the old adage : Keep Your GM Car All GM.
