have original 426 engine - pretty stock
recently worked on timing - got that straightened out and car ran fine all summer
alternator went so replaced that a couple of weeks ago - things were fine
starter motor died - replaced that - things were fine
replaced freight train of a fuel pump with a really nice quite holley (pn 12-125) - car seemed to run fine - but now it is bogging down
so i'll be driving along and notice that it drops in revs a little now and then - and if i get on the accelerator i get a mixed response - so me accerleration...some bogging -
the pump at idle purrs right along - i would think that would be the obvious thing since that is what just changed
but if it weren't, what else might be causing this?
thanks as always to the moparts sleuths!!
