I see most like the 750's and there are some that like the 660's. My thinking is to err on the small side with the 650's. It seems the Indy tunnel ram has a very large plenum and I thought maybe the smaller carbs would help crutch this on this combo. 5100 stall and car weights 3380#. Appreciate your opinion on this. Thanks



I would throw the 660's in the river. Or sell them to someone still living in 1975. The absolute smallest carbs I would run would have a 1.410ish Venturi and 1.750 throttle blades. There is no reason you can't call Dom and do a couple of 1050 Dominators and really kick [censored].

No vacuum secondary carb. Most guys err on the small side and don't buy a cam for the TR. If that cam wasn't ground specifically for the TR I'd sell it and get one that is. And a minimum of two 750's. A very, VERY smart guy who worked for a very cool company once told me to really get the correct carb on a TR you double what you'd be using on a single 4. And he told me that in 1982. It still stands today.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
