The Offy will bolt right up to most anything w/out having to modify/cut/grind brackets, headers you name it.
I personally like the OFFY better for low RPM & better throttle response.
The Clifford intake runners are HUGE as compared to the OFFY & IMO, the OFFY gives a better signal to the carb. I also got better mileage w/an OFFY over the Clifford.
My testings were all done on a 250 CI engine, so I would think a 292 could get away with the larger runners, but for a daily driver & concerned a bit about mileage, IMO, I think the Offy is a better choice.
There is a member here that did testing on the two different manifolds & carbs & the Offy did squeak out on top over the Clifford, performance wise.
That is what I like to see in testing, real street/race cars, testing on real streets or tracks, not just engine dyno testing.
