Clutch Fork/Bellhousing Interference

[james schaechter]

I have a QT in our Nova and have run soft loc, advanced single 10 inch, dual 7 inch and a dual 6.6 Boninfante. They are nice bellhousings. They do make a ton of different models. The only challenge I ever had was that it was about .200 shallower than the older style Lakewood or McLeod bells. When I used the clutch that was spaced off the flywheel and had a thicker disc, I ran the rm-198 spacer and it took care of it all. I also have a steel Browell with the heim joint and billet fork. They are pretty close to the same. The difference I saw is that it was about .100 deeper and the heim joint deal was nice. I had to cut the helm shorter to work with one clutch. It looks like the Browell is scalloped out near the pivot ball mount. The Browell was about 3 lbs heavier than the QT. I have not really bought any new QT stuff since they got bought out by Lakewood.

One thing I noticed, is that jerry Bickel sells a chrome moly foot that you could bolt to the inside if any bell to convert to a billet fork. I bought one, but I haven't switched over yet. I do like the billet fork. Main reason is for the use of a throwout bearing that stays in position when installing the trans. Of course the billet fork, is almost 300 and the bearing will be at least 80 bucks.

They all work. If I had a good QT, I wouldn't change brands just to change brands. In the Superstock car, we now have a 7.5 deep alum bell with a window and it is awesome! Again, it goes way up in price. I think if you were really loaded, you could do an alum for a 142 tooth flywheel and it would fit in a stock tunnel. $$$.

Just to answer a few of the questions that have come up in this post. This is a single disc set-up. The disc is .380" thick. I have removed all of the spacers on the throwout bearing, it is as short as possible. There are .070" thick shims between the pressure plate and the flywheel.

Will the Browell billet fork set-up work with the Quick Time bellhousing?

It seems to me the area on the transmission face of the bellhousing near the fork should be cut back to allow for more fork clearance. Another option would be to reduce the thickness of the transmission face plate (on the engine side) to give more fork clearance. The plate is .430" thick, milling a pocket .200" - .250" deep in the fork area would help. I think this is something Quick Time should consider. Again, thanks for all the suggestions and comments.

Another more controllable option is to have the disc cut thinnner and pull the shims out from under the pp. you might be able to run a lighter pp spring or cut the pockets deeper in the pp. I understand that a thicker disc may last longer, but we ran out discs multiple seasons so being real thick isn't a necessity. There is a lot that can be done if you want to spend money, but I assumed you would rather not have to buy a bunch of stuff. When the pp is spaced up like that, you will have close quarters even with a std depth Browell.
