My '69 came with a Saginaw floor shift 3 speed, which I am now changing over to a Muncie 4 speed...... the current clutch plate is the 10.4 in.... the Centerforce Dual friction is 11 inches..... does this mean I have to get a different flywheel or are they the same flywheel, just different clutch plate sizes ???

yes you will have to go with a 14 inch fly wheel for an 11 inch clutch.i believe this is correct.what you have now is probably a 12inch flywheel

Well I did a search and it looks like you are right.....

12.5 inch flywheel goes with 10.4 inch clutch and 14 inch with 11 inch clutch.

I guess if I want to switch to an 11 inch clutch, I would have to change the flywheel, clutch fork and bellhousing.......

I think I'm just going to stick with the 10.4 inch and not have to change a ton of stuff.

Is there anything else that i need to change going from a Saginaw to a Muncie ?? The bellhousing is the same isnt it ????

There are 14" flywheels drilled for both patterns and 14" flywheels drilled for 10.4" only in addition to the 14" flywheels for 11" clutch we typicaly see on big blocks and 350 small blocks. I just swapped out the big 14" flywheel/small 10.4" clutch for a small 10.4" clutch/small 12-3/4" flywheel.

More to the topic...Centerforce sells the 10.4" as well as the 11" in dual friction as I have the 10.4" DF setup on my car. As I remember, the catalog online is a bit confusing but they do make the setup you want. Jeg's sells them for $265 under P/N 183DF271675 for the 10.4" x 10 spline and throwout bearing P/N 183N-1716 for $33.

You will need a "403" bellhousing and dust cover. No biggie at about $50 and $12 Respectively.

I wouldn't go to the trouble to change everything out. The 10.4 incher will work fine. I use a Centerforce II 10.4 behind my 500 HP supercharged small block with no problems.

If centerforce GAVE me an 11" clutch, I'd still go out and buy a 10.4 to use behind my planned high 500 horse SB.

Thanks guys.... I'm going to stick with the 10.4 inch set-up

Is there anything else I'm going to need to change to go from a Saginaw to a Muncie ???? Bellhousing ? Clutch fork ?
