Has no numbers stamped in this except "07". It measures roughly 10 inch. He informed me that is was flashed in the 4K range with very mild big blocks. Im almost 100% sure its not a Turbo Action Unit, they usually are cut out around the backing plate/starter teeth area. It might be a B&M unit?

I can get pictures later today of both sides and if you'd like and see what's marked on it. I know there wasn't very many markings. If you send it away to get freshened, send it to PTC and have them put a new snout on the crank side. They were very thin and cracked along the welds, been there - done that.

Wade That would be great. 10-4 on the PTC, they have done several converters for me.

Al, Now that you mention it, you're right it does look more like a Fairbanks...I didn't notice what looked like the old "tiger stripe" black & tan paint that fairbanks used to use...Could still be the same type Core as a J but WIZE World's Quickest Diahatsu Rocky (??) 414" Stroker Small block Mopar Powered. 10.84 @ 123...and gettin' quicker! https://www.youtube.com/watch?v=-mWzLma3YGI In Car: https://www.youtube.com/watch?v=PjXcf95e6v0

The picture and paint look deceiving, I don't know why it looks like that in the pic, through the naked eye, it looks like a dingy scuffed black paint job. I only assume that at one time he painted in orange, and some time in the years past painted it black... OR Might just be his own creation of a Chip Foose custom paint job..LOL Last edited by Rapid_Transit; 02/01/09 02:39 PM.

Mine stalled around 4000 also had a fairbanks that stalled about the same but was way looser on the big end was supposed to be similar to the B&M not even close. They did look very similar. No stamp probably fairbanks.

If it is red about the only red converters I know of are built by Hughes Performance. Of course I have never understood the "J" mystique.

If it is red about the only red converters I know of are built by Hughes Performance. Of course I have never understood the "J" mystique. IMO These converters are nothing special. But 20 years ago they were. Now custom converters are made by everyone, and easy to find. These converters work pretty darn well though. I can say they're as about as efficient as one could expect. Again IMO they are not a all out race converter at least in my book. One couldn't compare these to a custom 8" or 9", just not the same animal. These converters work extremely well on the street, or a duel purpose car. The last one I had was a Turbo Action Unit I sold to a member here on Moparts (kicking my self). I had the converter updated by PTC, cause I thought, along with many others, they could make it work better...Well it didn't. I think converters are hit or miss, and custom converters too. I don't care if its a custom converter or what, most people are content with how they perceive they're converter work. I know it can take several tries to see what a combo likes. And can get expensive quick. I didn't set out looking for a "J" converter, a buddy had it, when I told him I was in the market for one. It was a good deal, I know the history behind it, and usage since new, which was "run" very little.

I had a B&M and a Turbo Action. They ran nearly the same. The Turbo Action was a liitle looser. They did not look alike. The one pictured here looks more like a B&M. Mine were about 5-6 percent. I tried other converters,none were quicker. My friend worked on the J project at Chysler. He said that there was a lot of Dyno time developing that conveter. Way more than any probably spent today. I agree, converters can be a black art. I've had some from some name guys that wern't very good. At the same time those same builders did a great job for buddys combos. Try it in the car and test it.

That's my results too, it actually slipped less than a 9 inch $1200 Coan converter that I ran in SC dragster which was about 8%+. And the same for the 8 inch Custom T/A converter I ran in the Dakota another $1000+ converter... Still not bad IMO for converters that flash 6K+ or so, compared the the J which will probably be in the mid to high 4K range.
