i thought you scanned that friggin story...

yes and no - Case in point - ME! I have a 400 hp 360 3.23 gears and a 3800 stall dynamic 9.5" converter I used to have a mopar 175k converter with the same setup and burned it up with the tranny - Why? It was slipping. The 9.5" dynamic converter lowered my cruising RPM , raised my...

i had a mopar cheap $200 converter and ran it for a few years - I swapped to a dynamic 9.5" and what a night and day difference it made in the car - drove much better on the street - even at 3800 stall with 3.23's!!! compared to the 2500 stall of the mopar one It lowered my cruise rpm about...

keep us posted my 3800 lowered my cruise rpm by 300 or so compared to the mopar 175k I was running before that

I think you can get the best of both worlds with a new converter - I';ve been running a dynamic 9.5" for about 7 years now - It's a 3800 stall that works great with my 3.23 gears - my setup is similar to yours - and I run 12.50's in the quarter with the 3.23's and a short tire. I drive the...

sweet thread

the brass ones are built to flow better at the sacrifice of filtering less.

dont run a brass one on the street.

I set one up last year - you dont need any special bearings. see if this link works http://www.amosauto.com/Articles/Mopar/Tech/8-34-rear-rebuild-for-power

so the challenger in my post now has 114,000 miles with the original syncro's, gears, shafts, and shift plates. It needed bearings, gaskets and seals - so what longevity are we loosing running ATF?

my dad bought a 1970 challenger new in late '69 - it came with AFT - we rebuilt the tranny when it hit 112,000 miles ( hard miles ) and guess what went back in? ATF. we didnt need any syncros, or gears either... so if the tranny has been taken care of the atf will not wear any more/ less then...

you can swap them - the driveshafts are different lengths so keep them together if you can

depending on the yoke - you might need a conversion u-joint - they both came in 7260 and 7290 versions. other then that you'll just need a housing gasket

i run my 8.25 with slick and run 12.56. Had it inthe car since i put it on the road 14 years ago.

both of my 8 1/4's have the vent - sorry never broke one but you do need the vent to maintain a service life.

yes... i had it behind the 318 for 10 years and the 360 now for 5 its a sure grip and I believe they are a little stronger. I cant kill it - thats for sure...

I've ran 12.56 @ 106 and have been 1.76 60' times with slicks on an 8.25... put 18,000 miles on it too - hundreds of runs with 2 motors... its lasted!

perfect example : joe - 360 , 3.91's 28" tall tire dymamic 3800 converter @ 50 mph 2400 me - 360 , 3.23's, 26" tall tire, mopar 2500 converter @ 50 mph 2400 when i went to a dynamic 3800 it dropped my crusing rpm by 400 rpm - thats alot less heat, wasted rpm, and mileage by switching to a...

what Joe said.. .positive pitch, and blade angle, as well as the stator have alot to do with it...

and thats exactly the 40 year old technology we are talking about. There are MUCH more efficient ways to achieve the same goal.

Dave - you talking Dynamic in CT or DE?

lol... yeah i did...

bottom line - ATI said the same thing... i'd burn up any trans / converter if i tried this.... you know what? they were wrong! I called Dynamic and ordered a 9.5" converter built to my specs. I HAD a mopar 2500 converter in it before - 3.23's and a 2500 mopar converter, that acted like, well...

yup.. At least call him up - you asked for an expert - and thats him. He helped me with this a few months back - I learned alot from him. http://editions.amospublishing.com/MPRE/Default.aspx?d=20090501&pagenum=40

the only person I'd recommend is John Cope of CRT - but i'm not sure how far away he is from you - www.coperacingtrans.com

I have a dynamic also - night and day compared to my mopar performance converter. Read this - it might help educate your decision - I went to dynamic's shop for the day ( Frank Lupo) http://editions.amospublishing.com/MPRE/default.aspx?d=20080401&pagenum=75

yes - you need a new front pump & input shaft. you also have to modify the valve body to block off the lockup.
