Uremco’s Holley 1920. Just don’t do it.
The 1920 is a factory piece of crap.
IDK if I would go that far;
they worked fine when everything was new.
But after a few years, engines with them installed do get to running crappy . But part of that is also the crappy retarded timing they run.
If you take the time to fix the timing, clean out the plugged cross-over, and clean the carb out, it ain't so bad. Plus they are really borderline too lean to start with; so a lil drilling here and there and then Presto!, back in action.
It's just a carb; and heaven knows we spend hours and days tuning 4-bbls.........
