The manifold is just like this one

I'm going to have to ditch this thing, aren't I? Looking like I'll have to run an adapter. I hate adapters. If so, any recommendations on a nice dual-plane intake to run with a Edelbrock 1403 with either of the cams we talked about above?

That's the SAME intake I ran & the Rochester 4-jet fits on it. Also a WCFB carter fits, but DON"T mess with those! If you find a 327 intake that has the secondary bores larger than the primary then that intake fits an AFB. I prolly still have a 4-jet up in the barn, intakes, heads, a 360 Offy intake & I know I have a 283 / pg from a '64 Impala.
