I use second. I was told to start in third and shift it to fourth but my box isn't clutch less or even face plated. So I just use second and call it good.

I was using 2nd also for so long because i grenaded so many 3rd gears in the tko600 boxes, i became paranoid about that gear. Its amazing i didnt just race using 1-2-4. Then i put in a jerico and now do burnouts in 3rd and shift gears not even worrying about it.

I try to stay away from burnouts with my A833...I guess 2nd gear would be it for me. If I were, I would at least turn my PP back to the 200lb base and go from there.

I am not a hard core racer, and I just like going down the track anyway.

I've broken the 2.65, 2.44 and a 3.09 boxes. All this crap about flex and not power shifting third is just that. Crap.

If you are breaking the gearbox your clutch is doing it. Most guys can run LESS than a 1000 pounds of static and tune with some counter weight and never break 3rd gear.




Yep, the clutch is the problem. I always like the RPM's to go up when I power shift instead of dropping. Really helps lower you ET . And also, the smell of the burning clutch disc is such a wonderful aroma. And for you guy's that are going to have a hole cut in your scatter shield, don't forget to do the floor also as that's how you get at the pressure plate at the top of the transmission.

ok, the 3rd gear is the weakest gear. that's why you can break it!!! 2nd gear is the best gear to use. unless you have a clutchless trans, you don't shift gears in water box!! herb mccandless said never use 3rd gear for burnout! I ran 833 for 32 years, did burnouts on every pass, now I have a jerico. still use 2nd gear.I did break a few gears in 833, but trans was raced a lot!! I can count on one hand , times broke the 833.

From the pics posted it looks like the window is cut in the bottom of the bell housing not the top.

Yes, that is mine, and I have a lift, so that is how I adjust it.

I am not a hardcore racer, so for me it works out just fine. Chris at Hyatt Racing can make the cut out, however for it to be certified, the window has its size limitations.

So, if I use the slipping clutch, I can use a 23 spline behind my Hemi?
Still haven't been told how to adjust these clutches. I can see where one turns the bolt-screw, but there must be some type of guage used, not done by feel I hope?
If starting from scratch, what size would you use 10-1/2 or 11" ?

The Manual that Tim Hyatt produced for me was turned all the way out CCW was 200 lbs with a certain number of shims between the PP and flywheel attachment bolts. I will need to look that up for you.

Turned all the way in CW is 1200 lbs of base on the McLeod Softloc...

My Ram Long Style with weighted fingers is 1800 base, and adjustable to 800 lbs. Ram sells a number of Long Style 11” under truck pulling PP’s.

Ram and McLeod are exactly the same, just a different color, and the Ram is 11” and McLeod is 10.5” PP.

McLeod sells both the 10.5” and 11” sintered Iron Discs for a great price. Ram and McLeod used the Same supplier for the disc’s. I can’t tell the difference.

Seems Ram is more interested in working with the end user, and McLeod wants you to work with a racing clutch shop.

BR, Mark

Pic of the Tim Hyatt McLeod Softlok and a Pic of the Ram and Bell in my A833 car. Sorry, I did not take a pic of the Ram clutch, but they look and adjust the same, just a different color and size.

BTW, I am not an expert at this, and I am learning as I go...

Next question, do you have to buy flywheel-clutch and disc as a unit? Aluminum or steel flywheel? Pros and cons. Street- strip car, 70% street.

Why do you think that Ma Chrysler put an 18 spline behind a 440 or a Hemi back in the day? The 23 spline has a lower HP and torque rating than an 18 spline by over 100+hp/torque..... Just look at the difference in the gears between the two.

the base pressure is set by, turning the adjusting screws in the pressure plate with allen wrench.we have a hole cut in back of bellhousing for this . we use a long allen wrench to reach in and adjust clutch. you can turn it 1/4 , 1/2 3/4 or full turn to raise or lower pressure. no shims are required. we use a speedhandle, rotate to hands on a clock, 3 clock, 6 clock 9 clock or 12 clock, very easy and simple!!! on the mopar trans, the upper right side bolt hole lines up to adjuster. you do have to index the balancer to find the spot. on jerico, had to drill a hole, 1" in back of housing. it's not complicated. BTW, you use a aluminum flywheel, it disapates heat out if the clutch.

In a heavy car use the Steel Flywheel, I tried an Aluminum Flywheel on the street, and it was very bad!

In a race only, then I guess it will still depend how heavy the car is...
