Sue is right. Can't be done if you want to go a minimum of high eights. Island Hemi bought so long ago it was with Confederate money. Just kidding Chuck, your LO23 is BAD! CW could do the work himself but no eights with a budget of even $50k. Lets ask John Holt, Ken Keir, and Mike Roth what they could build a high eight second SS/AH legal car for. They can eat the labor. No attempts at Best Appearing trophy.

How much for pipe, plumbing, wiring, drivetrain, wheels and tires, brakes, basic interior, decent Barracuda/Dart body, glass fenders and hood, and minimun bodywork to get it in primer? It needs to get through tech, not park by Bucky or Bales.
You can find an old round port RBRE with a crossram used for about $25k that will go eights and you are already halfway through your budget.
