Glad to here is running w/no leaks.
Hope you enjoy it!
Just a side note & not to bash you in intake manifold choices.
(so, dont take this the wrong way)Just my own personal experience.
I ran both a Clifford & Offy intake manifolds w/different carbs in different 250 CI engine combos,low compression,mid & high compression engines.
If you do not have too much compression, I had better driveability & better overall acceleration with a Offy intake.
I like the looks of the Clifford better,but actually won more races w/a Offy intake.
It's all in the combination,but w/a Clifford intake I would suggest nothing under 3000 stall on a torgue converter running a cam w/230 degress duration @ .050..
And that stall is more for a high perf,street use,you can use a low stall, but it matters on your camshaft specs & other things, not just one thing.
Just something to think about if you come across a Offy intake.
Might be a different story w/a 292 engine,but what I know is mostly based on 250 CI combos, in a 3000 - 3400 car.
BTW,what type of exhaust system are you going to run?
