Okay here's my problem/questions:

I'm wanting to rebuild my 283 and I want to go 4 Barrel BUT I've only found it quite impossible to go 4 barrel without having to get rid of my A/C unit (Original I might add, and it works still) because of the castings I see on all the Edelbrock and Holley manifolds, nothing looks similar to how mine is set up. and If I can still have my A/C unit I really don't want to move it because I'll have to probably buy new piping for the box that has all the controls and air duct pipes connecting to it. Also, I haven't looked at the intake manifold close enough, but if I'm not mistaken the oil feed tube to the crankcase comes through the intake manifold infront of the waterneck.. I haven't seen an intake manifold that has that loop for the oil feed. I really want to hop this 283 up but I don't want to get rid of my A/C since its so cool that I even got ORIGINAL A/C.

Heres a the picture of my engine, I'll be sure to get better pictures if theres enough requests to see more to help me out.
