Dale Coulter said

ok here's a real knee slapper. I can ask 10 people about a torque converter and ill get 10 different answers.
so, I have a 67 barracuda full tub car,w/cage, housing a 71 340 30 over, cam 508/292, rear 4.10, tire 29/18.50/15 weight of car approx. I'm guessing 3200 lbs. trans auto, carb 750, intake comes in at 1500-6500 heads 302 cast with port/polish and am/fm radio. question what would be a reasonable stall conver, for this set up. is that enough info.

Contact one of the better known HIGH STALL BUILDERS. They'll ask you a ton of questions, and ask if you've got a dyno sheet on the engine. You'll get lots of companies mentioned on this board, and my suggestion is to contact them all. Find out what they recommend for YOUR PARTICULAR SETUP. Typically they will have a specification sheet on their website, fill it out honestly and go from there. Avoid going to re-sellers of high stalls as while they may have some knowledge of how a high stall converter might work for you, only a builder of converters has the knowledge and experience to get you the right converter. Ask about warranty, ask about quality of their product. The better the quality the higher the price. Price alone should not be your only guide when buying a high stall.
Something you've got to keep in mind is just because I have a car similar to yours and have a converter that really works well doesn't mean that it will work worth a damn in yours.
In my opinion avoid used converters. They're a welded together piece, and unless it's cut apart and inspected, you have no idea what condition it's in. A flashy paint job and a nicely polished hub mean nothing on a used unit. I've seen enough used converters cut open during my time in the industry, to see some of the junk trusting people have bought.
Just my 2cent worth.
