My 383 is weak!?

I asked my dad about the engine and he said it has 452 heads on it and an edelbrock intake on it. I'll see if it is the Performer or RPM Performer tomorrow. I did read over and save the build you guys had mentioned and will look at a cam around those specs for my engine. I do have headers as well but not sure on the size. It seems I have the makings of a powerhouse of an engine just need a few parts. I may get around to checking the compression on each cylinder this weekend if I can find my tool. Hopefully that will come back good so all I'll need to do is look at the ignition system. I would like to go to a Edelbrock carb too. My Dart doesn't smell horrible but both my pickups with Holleys just smell awful and if you idle anywhere you smell awful too from the fumes around the trucks.
