Hot Rods ST400 Switch Pitch converter

I got Bruce's number off this thread https://www.jalopyjournal.com/forum/threads/th400-article.228842/page-3 and just ordered a kit

 

Bruce said he is going to do one more build group, so his controllers are available. I'm quite happy with the one I have. It switches to high stall when you brake and stays there for I believe 60 seconds after your release the brake. It will also switch to high stall if the manifold vacuum drops below a certain value. It acts like a part throttle passing gear.

The Cadillac's I used did so I guess I was lucky. Then again that was in the mid 70's' but used on in a 8.90 bracket front motor dragster, with 400 SBC. At Green Valley outside Ft Worth.

 

Since we're here, just a callout for a stock 400 Switch pitch converter, or maybe a 300, (wasn't aware they interchange.) to anyone near Atlanta. I'd hate to ship one these days, so if your nearby....
What are the stock stall ratings on a 300 SP?

 

Somewhere around 1500 low-2000 high is pretty common for stock converters. The smaller 300 converters are usually 100-200 higher than the larger 400 converter.

I had one stock rebuilt 300 converter that gave me close to 2500 in high stall. That's unusual.

 

Trishield Performance does Switch Pitch transmissions and converters. Jim Wiese.

 

is he still around? I thought he was long gone...or maybe it was just a bad experience with him made me hope so?

 

Wiese is the only one I know of still doing them, Jim Burek out of El Paso is not around anymore that I know of. Did you have a problem with the one in the Nova?

 

I've been through a few converters in a few different cars. The one I have now was done by one of those guys, but I don't remember which. It got rebuilt by Hughes several years ago, and is working pretty well still.

 

I've got by with toggle switches on mine for the past 40 years or so....
