FWIW I rebuilt my 283 last summer and did the following. Bored 030 over with flat top pistons, Edelbrock 2102 cam, performer intake and 500 carburetor. I used 416 casting 305 heads and the stock points distributor. Transmission is the factory powerglide with a 3:73 rearend. Performance is a little sluggish at a stop sign because of the powerglide but the thing really comes to life at about 2500 rpm and it flat screams to 5000. Swapping the glide out for a TH2004r would probably do more to improve performance than anything else. I'm happy with my results.
