2bbl on single intake

Maybe a larger single? Don't know what that might be? Maybe something off a 300 cid Ford or 292 Chev?

Also if you can braze, you could modify your stock intake, or buy a "junker" and play with that. Build a mounting plate, say, 1/4" steel, fit it to the intake, grind out the porting to match, either mill a flat to mount the plate or close, an braze it on, or if milled, drill and tap, bolt it on
