mid 80's clutch pressure plate rating 10" vs 11" ???

I have a 4 spd OD RUG box behind a 300-6 4.9L in a 1985 Econoline with stock 10" clutch, but the flywheel is drilled for an 11" also.

I'm looking for a performance upgrade, but...

When Ford changed to a hydr clutch pedal on the van, they mounted the master cyl to the sheet metal floor. Not so durable. I had to weld my floor up and double skinned it. I don't want to increase pedal force much because of that.

Does the stock 11" clutch have much more pedal force than the 10"? I see ford used the same master/ slave for both the 10" & 11" clutch (according to RockAuto listing).

Any other recommendations?

Summit lists a Zoom MU30-1 with this generic marketing blurb
"These Zoom MU Series clutches by Perfection are OEM replacement clutch kits that provide more grip without the stiff pedal of most aftermarket clutches."

How much more grip?

Thanks.

I had that same set up. No clutch troubles other than the floor flex, for which I made a reinforcement. I wouldn't fiddle with it--you will find the next weak link in the drive train, which may be that OD trans.

I planned to swap a T5 into mine but never got to it. I had 3.50s and 31" tires--a bit of a pooch and 2nd to 3rd sucked.

Sometimes I miss that trans, so I just skip gears in my current 5 speed and shift at 2800 rpms......

Carolina Clutch sez pedal effort similar

Thanks for the input.

I'm rebuilding the box now.

My rear has a 3.0. Probably go to a 3.3 or 3.5 after I get the torque curve figured out at cruise RPM.

What kind of MPG did you get w/ the 3.5s I can hardly use OD unless I'm going 70?

searching the other posts I found reference to Carolina Clutch and sent them an email. Just got a reply....

"As long as you have the mechanical rel brg which the clutch fork slides into you can
use either 10 or 11. The pedal effort on either should be very similar"

I might have gotten 18 or 19 once. I seem to recall 13 once. The tires really goofed it up, other than they looked lot better than the stock donuts. I never really tracked it. I drove it about 10000 miles between 1991 or 2 and 2009. Getting married and having kids changed a lot of plans.....
