    Recently installed a tr with a single carb and I was wonderin what carb would best suit the tr . My old carb is 750 vac sec. and it used to run really well but I know it wont with the tr. Any sugestions would be helpful.

    I would say you don't need 1 carb, you need 2. Tunnel rams and single carbs do not work toegther very well. somthing in the 450 cfm range would work well. Alot of ppl get that bigger is better stuck in thier head and end up costing themselfs alot of headaches...
    FWIW 2 vac carbs index toegther are far ezer to tune then 2 mech carbs...

    u will find out after talking to people in the know, that a sgl TR is not the way to go...they have a habit of puddleing fuel in the corners & do not run well...i had 1 on my boat & took it off after i found that out & now it runs much better...if u must have a TR...get a dual top & run 450/600cfm carbs...u will be better off...if u decide to go to a sgl carb & manifold...i recommend u try the Edelbrock Air Gap dual plane with a 750/850cfm mech sec...they work awsome...just my .02 cents

    Really? I ran one for quite a few years with a single 830 Holley and a pretty mild 468 (8:1 compression) and my lake boat (full gear, stereo, coolers, seats, etc.) was bouncing off 80 mph on a consistant basis on GPS. Guess it all depends on how you set it up. Oh, and it was a jet.
