Nice car! I would go light weight pistons, balance and clearance the motor, deck the block, Edelbrock heads, high energy cam, recurved distributor advance, 170 thermostat, flexilite fiberglas fan or clutch and stock 7 blade #216 fan, aluminum intake and Edelbrock carb...3.91 or 4.10 rear, exhaust system. If you want it to be factory appearing, I would stick with the cast iron intake, go with a 440 Carter carb and maybe different heads but you could stick with thealuminum heads and just paint them.
