Edge Racing Converters

[80ZED28 EH]

Anyone with any experience with these guys? I inquired with them and got this info back:

Hello and thanks for inquiring,

I recommend a custom configured converter from our "Street Edge" series with stall math set between 3400-3600 rpm, and STR set at, or near 2.50.
This converter uses the 245mm (9.5") impeller and turbine (furnace brazed).
The 9.5" impeller is the most efficient impeller ever adapted into
performance applications. With 8 impellers and 8 stators to select from this
converter can be truly custom configured with no cutting or bending inside
the converter. This means better launches are a guarantee, better mid range
response is guaranteed and no excess heat or loss of topend, guaranteed!

All the gains while retaining 100% of the manners needed for every day street use!
All wear surfaces are fitted for enclosed Torrington bearings for less
drag and improved longevity in performance application. The drive hub and
spline insert of made of 4130 chrome moly steel. Anti balloon measure is
standard.

Warranted for a full year with our 100% money back satisfaction guarantee.
The "Street Edge" TH350/400 sells for 450.00 plus shipping

I bought one for my 71 Camaro/LT1 FI swap to mate to my TH350. Pricey but from what I understand it is WELL worth it. I frequent the 94-6 Impala/Caprice LT1 boards a lot since these are my other car hobbies and the Edge 9" lockup converters (even for street use) are regarded as the best choice at $550 even to the might Vigilante $700+ converter. Supposedly comprable in performance for much less $$. I'm even in a car club where a couple guys have these and they say it is night and day difference from having a cheap converter versus a good one like an Edge.

Very good reputation in the LT1 community.

I have yet to do my swap so I can't comment on personal use unfortunately. But I think I'll be pleasantly surprised once it all goes in.
