your only choices are edelbrock ch4b, dp4b, or mopar m1 dual plane. These are all similar height to stock iron. The torker and Holley street dominator are a little taller and may fit with a B engine and 440 air grabber base plate. The RPM is not going to work without a 2" drop base, even then no guarantees on an RB. The dual plane M1 performs like the stocker, just much lighter and easier on your back to install. I use an m1 dual plane on a 383 with 440 base plate on 70rr n96 hood.
