I never thought about costs versus return on fuel. Car will have a decent build 440. I haven't finalized the build options as I tend to always want to go overboard. But stock stroke and 0.30 over pistons. I have a completely done set of 452 iron heads with minor smoothing, no porting. And a set of used Edelbrock heads. Not sure which way to go there. Drivetrain is not numbers matching and I started to think about making it more modern with fuel injection, more gears in the transmission, and other changes. The idea is to do that versus buying a modern muscle car. I'd love a manual, but was leaning towards keeping it an auto.

Thanks for all the suggestions. Certainly some options to think about.
