For now, I think that I'll go with a 500 edelbrock carburetor, performer intake I got a great deal on those, a curve kit, "chrome " box, good wires,plugs, mandrel bent 2 1/4" exhaust system. 3.55 gears. Fun time
It's best to do things in steps see where it takes you, not every has do be done once, look at 318willrun's hop ups to his 318 duster got good gains with a few basic hop ups.
Plus you may have to experiment a bit everyone is different how they want their car. That's part of the fun.
