"Baselining" my 225

I've about convinced myself to go ahead and swap out the distributor with one from @halifaxhops .
I'm told that the timing curve in this one is wrong (not enough initial/total advance) for the 1980 engine. It certainly feels a little sluggish off the line and fuel economy sucks.

Which leads me to the carb. It's also not correct for the car OR the engine. It sure has a bunch of plugged ports and unused EPA B.S. on it.
@slantsixdan , what would you suggest, carb eise?
