Does Neal Chance not make a bolt together converter for a 727? He's been making bolt together converters over 20 years. I guess no one w/ a 727 would likely buy one, b/c by the time you're serious enough to need one, 99% of those cars won't be running a 727.
humpty...you can make stall adjustments yourself if you have enough money for the extra parts to change out.

I've been using custom built converters for all my combos over the years, but never made any changes after they were built. Now I'm chasing ET's and am willing to make changes. How do you guys dial in your converters? Increase the stall until ET's fall off? Buy a few and use the one that works best? Thanks.

humpty...usually I have a feel for which way the converter needs to go after I make some passes w/ the car. I take it out and have my converter guy make an adjustment and try it again. I'm fortunate that my converters are built locally and he does it while I wait. Usually doesn't charge anything for a simple adjustment when sorting out a new combo. Most places usually give one free adjustment when you buy a new converter.
I've seen guys show up at the track w/ 2 or 3 spare converters and try each one. That's great, but expensive.

Data logging is really the best way. But just watching the tach on the shift and at the stripe and doing the math. To much drop on the shift means the converter is to tight, not enough too loose. To much RPM at the stripe will lead to excessive slip which creates heat and depending on the amount and combo could be costing ALOT of ET and certainly MPH.
Bolt togethers are definitely nothing new to the market but seeing ATI offer them for TF's is a good thing. Great for the Stock and Super Stock guys for sure. We run a billet bolt together from A1 in the heads up car. The ability to swap stators or spacing at the track is a big advantage if you are chasing every last ET. Especially when traveling and facing differing conditions, in altitude and weather.

Thanks for the info. What is the benefit of a bolt together converter? One advantage is that you can clean it out and check it yourself without having to send it in and have them cut it open and send it back.

And you can change the internal components to modify the converter's behavior.
These were introduced many years ago but were banned by some sanctioning bodies because of the exorbitant cost.

Just got done talking with ATI , and pricing isn't finalized just yet, but he thought in the 1900-2000 range. The converter is 4lbs lighter then a regular steel 8".
