Need a plan - component selection for restoring 68 340 that runs on 91 oct

Lots a computations...great theory to get into details.... but maybe veering of the given constraints.

Small carb that has little adjustments to tune with. 68 AVS carbs have lead plug in idle screws unlike all other years. I took the plugs out, idle screws don’t move. There is one adjustment screw.

Do the cams suggested have adaquate vacuum signal for THAT specific carb? Is that carb going to transition well? You can’t adjust throttle blades, idle bleeds, even fine tuning the float level is a chore.

I think something like a hyd comp XE268 range with 4” stroker kit with 9.0-9.5 max compression would make a fun all around torquey street cruiser. Similar cams in a stone stock 340 sounds tougher than stock. But not much in a stroker. Visually outside you can’t see stroke. Can run your stock rocker arms.
