Default 10.5 or 11 inch clutch 408W?

I bought a Mcleod 10.5 inch 800 series clutch plate and a 10.5 inch diaphram pressure plate. I also have the 164 tooth steel flywheel which will accept either 10.5 inch or 11 inch clutch. My setup is 408W, TKO, ford 9" rear.

Should I exchange my 10.5 inch clutch plates for 11 inch plates?

bigger is better! I went from an 11.5 to a 12 inch McCleod myself. You need all the clutch you can get it.

I don't know...these cars are awfully light. I think if you're running slicks...sure...but not with street tires...and not with a 2300 lb car. I'm running a 425ci Windsor, 9" rear and a Toploader....I have a 10.5 Hays Street/Strip disc and a 10.5" Hays Street/Strip B&B pressure plate....rated for about 2800 lbs clamping force.

Excaliber

Can you get a 12 inch clutch on a 164 tooth flywheel? Were you using a diaphram or long style pressure plate?

Blykins

No slicks and no drag racing, only street and road course.

Dave, Excal is running a big block.....the flywheels are a little bigger and usually drilled for bigger pressure plates/clutches....

I'd stick with the 10.5" piece....should be fine....

I bought a Mcleod dual disc setup, 10.5 inches. On a chassis dyno , I promise there is no slippage. When we testing, some of the best single disc setups would show slippage after about 400-415 rear wheel horsepower. I think I paid about $1400 for eveything, aluminum flywheel, cutch-pressure plate set-up, and their steel bellhousing. On the street, it has very easy pedal effort, when she grabs it is locked for sure.

bigger is better. If 12" is possible, you should go there.

I am using a hydraulic t/o bearing assembly. Man you won't believe how easy the thing works. Saves a bunch of space around where the slave cylinder suppose to be. Looks a lot nicer too. It is also the Mcleod unit. Congrats on the Kieth Craft motor, I love mine, you will love yours too.
