heat will be your enemy - as long as you cover that issue well - should not be a problem

BradH! I have about the same distance to the track and I wouldn't drive the car there. I get better mileage and less pita towing it to the track. I took my Dart to the track at Sonoma and broke the rear u-joint so I was glad to just push it in the trailer and go home. With a deep pan and not doing full throttle romps everywhere, I don't think my car is broiling the fluid even without a cooler. My Challenger doesn't have a tranny cooler either.

If fluid temperature doesn't rise in 20 miles, it won't move unless you power up.
I don't trust the fan-equipped coolers, too many reports of failure in 6 months etc.
I have a big cooler, read more here:

Jeff Paradise of Dice Converters is doing a lot of their stuff now I've heard...both great companies.

Ya heard the same out here in the Desert..............Driven mine 90+ minutes at a time and no heating issues w/a B&M honeycomb trans cooler and no more that 190 temps..........

Same here, I did it. MPG (or lack of) was my biggest issue!

I run an 8" Ultimate. Stalls at 5200 behind my 468.
3.91 gears, 40 miles at a time no problems so far.
I called Lenny and talked to him, told him it was going to see many street miles.
I basically said "build me what you think will work best".
It's been great.

Since I run OD I had Lenny tighten my 5000 stall
TA conv up a couple hundred rpm so it would be
a bit easier on the conv when in OD and keep the
slippage down.. he did a nice job on it... at that
time I had him cut off the mounting lugs and weld
on new ones.. my old ones were starting to strip out

GER was just glorified mini van convertors that were converted to run with 727/904's. I had one years ago that the local convertor shop wouldn't even touch after just seeing me walk in the door with it. Ironically it was the same as my 98 sebring convertor and you could see where the original mounts were ground off.

Back n the 90's I was running a 10in. GER convertor and I was hearing they were bad convertors. I bought a Coan 10in. race convertor ( over $600 back then) and my Demon slowed down over a tenth in the 1/8. Boy was I disappointed.

I had a ger YEARS ago... it was a POS.. any conv company
can miss on there set up..but now days they are better
but can still miss the set up
EDIT
The main reason it was a POS was the quality
of the parts... why do you think MOST conv
companies wont touch a GER cov

Using a Turbo Action 3800 8" converter on the street and was the same converter we used at the track. No problems with it and I use a big trans cooler. 3.90 gear with a 30.7" tall tire.

Thank you for all the replies. I feel comfortable now to run my 8" converter.

Been doing it for years and seen zero ill affects.
