I have a B&M Hole Shot 2800-3200 converter in my 69 468/th400 373 rear.
I slips alot around town up to about 3500, but when at WOT or 3/4 throddle it does good.
I would like to have it fixed to where it pulls better in the lower rpm range.
First off can this be done, second is it cheeper to just buy another converter?
This converter has less than 400 miles on it and is a 10".
All the converter people say I need this high of stall cause of the cam I have XE284 240-246 @ 50, but do I have to have the slipping at low RPM?
What do I tell the converter people?
Can they just tighten it on the lower end?
What would be a fair price to do what I want done?
Any advise will be appreciated.........

I guess 23 people also thought this was a dumb question?
Guess I should call and ask a converter company?
Just thought someone here had done this and could give me a ballpark as to what I can expect to pay?
Hate to go into these things blind...........blond?
Thanks T.C.

I don't know if B&M will tighten one up or not, call ATI,Coan,PTC, some of those and ask them what it will cost to tighten up your converter. I think ATI charges about 150.00 to recon one of their own converters. Have you ever had it to the track to see how it really acts? From those results you can calculate slippage if there is any.

I've got the same problem....408/284 cam/TH350/4.10....just driving down the road at 25-30 mph sounds like it's slippin....and it probably is....oh, that's a 3000 Hughes converter I'm running too.

Thanks for the reply:
Mabe someone will answer and give us some insight as to whats a fair price to have this done, or should we just buy new?

great question!! it really peaked my interest,,,mechanically nothing actually connects the engine to the transmission! power is transfered from the engine to the transsmission by fluid coupling. In other words the faster the turbine turns the more fluid coupling happens thus turning the input shaft in the transmission. So it has have a "Stall" in it at low rpms otherwise the car would move just idling. By tightening the convertor I`m not sure what they are doing? Are they changing the pitch on the turbine? Seems like you either have too high a stall or your clutch plates are worn in side your transmission causing the slipping or your fluid is low or the front pump has low pressure. Good luck and I would love to hear exactly what they do when they "tighten up the convertor"
