Going crazy here, but I have a 70 t/a with a 400 r/a3 auto and years ago carb was ripped off of it, but I just put a junk yard carb on, but now I Need to know what size carb is right for my car, I can't remember and I can't seem to find the info, is a 750 to big for a stock 400r/a3. THANKS

I think I have a 650 on it right now, and it seem like it's not getting the fuel it need at WOT.

Your '70 T/A came with a 750 Quadrajet carb. The Pontiac Q-jets came in 750 and 800 cfm sizes only.

Any 750 or 800 Q-jet would work fine, even the late '70s smogger 350 engines came with the 800 cfm version so you won't be overcarbureting a 400 with one.

Of course the most discerning owners of '70 T/As would prefer the correct matching 750 carb, maybe you're one of them.

Thank for the Info on the carb. yes I would love to have the org. back but thats not going to happen, well it could, see I know who stoled it from me, but thats another story, and another replacement well I would have to sell my house for. LO

If you know who stole it... you might want to get it back.... its worth about $3000 give or take..

Did the 70 T/A Ram Air 3 and 70 Formula 400 Ram Air 3 use the same 750 Q-jet?
