Aluminum bellhousing problems with 11" flywheel cover??

[javakmcharger68]

Just wondering if there are any problems with putting a 11" flywheel cover on a 71 bellhousing? May be a bad question, but it is better than buying something I can't use. Thanks

I believe all of the aluminum bellhousings are 10.5" for the later models so the 11" inspection cover won't fit. You can get repro inspection covers from a couple of different places (other than Year One's high prices too). I just got a brand new 11" steel cover for around $70.

So are you saying a repo cover that is 11" will fit? I need to get flywheel, clutch, pressure plate, and inspection cover, for my 1971 18 spline 4speed that is going into my 68 charger. Is there a big difference in the performance from using a 10.5" rather than 11"?? At this piont I just want to get this together with no problems. I bought a 12" clutch for this setup, but if it won't work in the aluminum bellhousing, there is no piont going in that direction. I just need an idea on what works so I can get this together without finding out later that I have to buy more parts. Thanks to all

I THINK he meant that the 11" cover will not work with the 10.5"  bell-housing, but a cover that will work with the 10.5" can be obtained for around the same price as the repoped 11" cover.  There are also plastic covers available, but it was recommended to me by Brewer's Performance to use the steel cover since I'm going to use headers (better resistance to hear and all that).  It has also been recommended to use a steel cover for the aluminum bell-housings as it stiffens/supports the aluminum bell-housing.  Some things to think about.

I'm doing about the same thing with my 68 Charger.  I plan to go with a 440 4-Speed combination with a (made sometime between 1966-1969)  B-body 18-spline A-833 4-Speed.  I bought all my 4-Speed stuff new or rebuilt from Brewer's Performance in Ohio (937-698-4259).  So everything in my setup should match up.  It would seem they put together for me a Pre 1970 setup with the 143 tooth flywheel and cast iron bell housing.  I BELIEVE I have the Pre 70 true 11" set up (NOT the 1970+ 10.95" set up).  Looking at the McLeod website, it appears you can only use the true 11" setup with an 18-spline. 

Go to online catalog, and then go to Domestic car clutches, Dodge:

I have a 143 tooth flywheel, cast iron Bell-housing casting # 2892262.  I also have McLeod clutch disk # 260151 their pressure plate # 360206.  I also have a steel repop cover.  Anyone know where I can get pressure plate bolts at?  Can't remember if I already have them. 

Numbers on the 4-Speed case that I haven't been able to decode:

If you still need help I would recommend calling Brewer's (937-698-4259) or Passon (570-401-8949), as they both seem very knowledgeable on all things 4-Speed, and of course they could sell you what you need

So if the 11" does not fit, what size clutch came in a 1971 dodge charger with 440 4speed(18spline)?? I guess that is my question

I'm kinda wondering myself.  I do BELIEVE that for 1971 it would have been the 10.95" set up with an aluminum bellhousing.  Not sure which cover you would need, but I'm sure one of the vendors I mentioned would know.  Hopefully Chryco Psycho or tecmopar will see this and clear things up

The 11" inspection cover will NOT fit the aluminum 10.5" bellhousing. You can purchase either size cover here:

Not sure where all of my 4-speed info went to at the moment but the later model 4-speeds used a 130 tooth flywheel so you'll need one of those to match the bellhousing or you'll never get the starter to engage. I have seen people use the smaller flywheel/clutch/pressure plate on an 18 spline trans as it is a bit lighter and allows the engine to rev faster. I'm not sure which clutch they used but I know McLeod will make whatever you want (for a small fee of course). Mopar part #P4529138 is for a 10.5" disc for an 18 spline trans. I think #P4529140 or #P4529141 is the matching pressure plate. You'll need the shorter clutch fork and the correct z-bar.

Here's some great info on 4-speeds and swaps in general:

the bell housing dectates what flywheel to use. the aluminum 513 bell housing used in 1970 and up uses a 130 tooth flywheel and the clutch size is 10.5 or 10.95 scalloped clutch, which alot of people get confused as an 11 inch clutch and it isn't.
