66 Impala Intake Manifold Q's
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.

So what you're saying is I can just throw on like maybe a 400 to 500 CFM 4bbl on the same 2 Barrel intake manifold but with that adaptor to make it work properly?

Oh thank you thank you.
You guys have no idea how much simpler this build will be because of your advice.

After looking at you picture I think if you tell them the intake is for a early to mid 1960's chevy with front oil fill you can get a good performing manifold from just about anywhere. You can use the same rear compressor adapter that is on your car. It uses the intake bolts over the 2-4 intake runner and the bolt tab for the forward compressor mount uses the alternator/generator tab. You may have to check at swap meets but there are plenty of early stock intakes [4bbl] out there.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
