Re: "Ol' Blue" '63 GMC
a little update...so we were having some drivability issues with ol' blue after the swap last fall and we didn't get much time to drive it, but my son has had it out for a week or so and found a guy that could tune it so he had him do it on Sunday and he found the problem/s....first of all it was tuned for a 4.3 v6..?(thank you PSI) and it was running really rich at idle and dangerously lean mid range. he corrected those issues and now it runs like a champ!
