Just how much horsepower and torque can an 18 spline 833 handle. Does anybody on here use the Passon overdrive 4 speed?
It all depends on the weight of the car. A 3200 lb. car is going to be MUCH easier on parts than a 3800 lb. car. Anything over 550ish ft/lbs of torque would be a good starting point for a "slipper" clutch. They are commonly made of sintered iron or kevlar. I am currently fighting this battle in my red Charger.
Just an observation, but that last picture shows what looks to be a 307 bearing (number on race), and that is for a 23 spline trans. The large 18 spline uses a 308 bearing, and is considerably larger. In your defense, you necer stated you had an 18 spline tranny.
Anyone that seriously races one of these cars is running a 727, TH400 or a glide.Not all 18 splines had the 308 bearing. The 66 and possibly the 67 trannys had the 307 bearings - 66 hemi cars for sure.
I wondered if the 68 SS hemi Darts / Cudas had the 307 or 308 bearing and it seems that mystery is solved. It makes perfect sense for Chrysler to use the STD A body tailshaft on those.
My comment on the power handling of the 18 spline is directly in line with GTS. For a street car they (and the top loader Ford) are unbeatable, but anyone who seriously races is running a Jerrico.

Yeah, but never really raced a transbrake true manual shift automatic car. I used to fall asleep driving my Trans Am with a TH400...click. click. yawn... click
I am probably going to be between 500-600Hp. thinking 4.10-4.30 gears. Maybe 11s in around 3300-3500lbs. 30x11.6 drag radials
Well, sure, but we are talking three pedals in this forum.

With a 4 spd you will likely need more gear like 4.56, unless this is for street only. Auto's have torque multiplication from the converter, which is sort of like a secret 1st gear, but the 4 spd guys have to make that up in the rear end. I know a guy running a 10 sec B body with a Jerrico and he has 5.13's.
I really want to run a semi-normal clutch for street driving and a lenco st1200. I am still taking measurements and trying to figure out just how big the hole will be and how far back! I wish the UMTR site was easier to get into. I can never get logged in for some reason.
