Yes, this is the intake I am using. Front carb is centered, rear is way back. Currently using front as primary w/ 51 jets and 3.5 PV. Engine is .030 over w/ stock ford crank w/ max-1 cam.

Seems to run decent except for idle and some backfiring through exhaust pipes. Difficult to get at idle screws w/ this set-up. Back carb butterflys seal tight in bores and have no idle screws, but still get air pulled in at idle w/ throttle closed.
