Quote from: Rbuddy98 on August 06, 2026, 08:37:02 PMI'm in the process of reviving my 1966 gt350 that came factory with an automatic transmission. When my dad bought this car in the early 1980's it wasn't running and missing some original parts. It's been in storage ever since. I have been reading that after car #800 they came with the 4100 series carb. my car is #366. What would be the correct carb? The last time this car was on the road and running was 1978. It's time to get it road worthy. My next question did the automatic cars come with the tri-Y headers? I have the motor apart and found it has a spun rod bearing and one of the cam bearings were installed incorrectly blocking the oil passage. It has a standard bore. Any info would be greatly appreciated.The correct carb for your early #366 (non carryover) would be the S2MS marked 3259-1 Holley carb. Later cars typically used the 4100 carb through the end of 66 production. It would also have Tri Y headers like every other 66 GT350.
Thanks

For example in this for sale ad if the seller would have said "mostly original" I wouldn't have said a word. Those that rail to condone this behavior are part of the problem.
Underneath besides the gas tank I stopped counting at all of the things that were changed out. It is funny that apparently the seller doesn't know what he doesn't know if he believes his own statement. I forgot to mention that the nut is missing from the bolt through the frame rail holding the PS ram bracket.
