My car is EFI and a nice ride, a real no brainer. Had a IHC pickup on woodgas with the MEN quadrajet carb and it ran fine. Had 2 farmall M’s, 300utility, 3 cub lowboys, dodge 800 series, 2 IHC trucks all with carbs and all ran fine. Oh, 2 jeeps also but replaced the CJ7 carb with an aftermarket because it was from the years just before EFI. Yes, I did tweak from time to time but easier to work on than changing brakes. Oh, 2 army 6x6’s.
Choose your poison, nothing is perfect… Sorry.
