In Need Of Torque Converter Education

I have posted here several times regarding my ongoing 1949 Ford F1 restoration. I have a 302 & AOD transmission from a 1985 Lincoln Continental in my Ford F1. The motor has been rebuilt with the addition of a Compcam's 0.531 lift Thumpr cam, 7-1/2" Funnelweb intake, 600 cfm holley, headers, etc. The engine seemed to idle good at 1,000 to 1,100 rpms but when I put it in gear the idle was pulled down to where it would barely idle. Compcams recommends a 2,200 stall converter so I installed a new 2,200 to 2,600 stall Road Runner converter. Now when I put it in gear, it will not idle at all. I called Road Runner and they say it should idle just fine. I always thought the higher stall the better idle I should get. Am I wrong?

Thanks in advance..........

Re: In Need Of Torque Converter Education

Good article rtg....thanks. It mentions if you go with a lower stall than required you would have idle problems coming to a stop at a light. I have went higher than I had before. I have read alot about timing & carburetor setup today. These will cause the problem I am having. Since I have only set the timing by ear so far and haven't checked my vacuum advance to make sure it is working, I cannot comment any further until I do. Will zero the carb in, set timing, check advance & fuel pressure this weekend. Will let you know how I make out. I am sure the new converter is a little stiff yet being new and all and may get better with time.

The whole article has good info. I know you wondered about the idling so I pointed that part out. Will be waiting to hear what the outcome is.
