I dont know the guy but he said "Adjustable Converter" so I assumed he meant bolt together which would = $ 2,000 Neal Chance unit?

Yep, it is not as hard as one might think. My ATI convertor was over $1100.00 and it is only rated to 1200. Some bolt togethers can get over $2000.00 in a hurry depending on what all you want. Then you add in a purpose built high HP TH400 and you can get pretty close to 8K if not over. I have $2500.00 in mine and it is not the best of the best by far although it has some very nice stuff in it. Add the two together and you have $3600.00. It may be a far cry from a TH400/convertor that costs 8K but I am sure the durability and parasitic loss isn't what his is either. I am sure his stuff is way better.

A quick search turned up the following

TH400 with the following - modified high flow pump, forged steel gears and roller bearing, billet 7/8 input shaft, intermediate drum, hardened forward drum, choice of chromoly planetary gear ratio 2.10, 2.20 or 2.48, roller bearings throughout, high pressure pro-brake valve body, seven clutch forward and direct drum pack, 5 clutch intermediate pack, oversized intermediate sprag element and outer race, billet steel forward clutch hub and deep aluminum pan. - $3595.00 add a dedenbear case to that and you are sitting at $4544.00

Another turned up the following in regards to convertors - 10" MAXIMUM PERFORMANCE STEEL STATOR CONVERTER, BILLET ALUMINUM COVER, BOLT TOGETHER, BIG SHAFT - $2495.00

That alone brings his total to $7039.00 and who knows if he had something else done to the trans. My point is that those of you calling BS might want to cut him some slack. That stuff there is just off the shelf. When I was crewing for a buddy who was running in Easy Street back in the days of the NMCA I remember him having a little under $5-k in a glide and bolt together convertor and that was 10 years ago.

To answer your question it is really a toss up regarding the overdrive function. If you want it then the 80 is the way to go. If not ****** up a good used purpose built 400 as there are a good many out there to be had for a decent price.

At the wheels? If so that is stout.

my 80 has performed flawlessly thus far.

i go through the traps WELL into overdrive. i get out of third at 134mph.

i have under 5k in my trans and converter.

Hey David,
What gears are you running? How much slip are you seeing at the top of 3rd? How much does the converter pull the motor down on shifts?

Big Geek,
I agree...He just made it sound like his buddy had $8,000 in the trans. Which is way high. But when you subtract out a $2,000 converter it makes a little more sense. I would say I have near that in mine but I basically have a Rossler TH210 with OD in a 4L80E case. I love my trans and Midwest converter.

didnt see this until now my bad.

i have 3.42 gear and the 315/35/17 is about 25 1/2" tall

the slip is very minimal, i wasnt pickign up mph from locking so i just stopped doing that to save the converter.

i am still about 750 or so rpm drop on the shifts, exept going into overdrive i think thats 500.
