Clutch Disc for Ford based T-5 Swap?

Post #1 by 62Cometman » Mon Jan 28, 2019 10:15 pm

I have found that the clutch disc for the Fox body mustangs with the 2.3L is a larger 1 1/16 10 spline 8.5 inch clutch disc. Does anyone know what the factory 8.5 clutch disc thickness is? Also contemplating how much power can be put through an 8.5 clutch disc and the original pressure plate? Maybe 200hp? Honestly wouldnt be shooting for much more anyhow.

Im thinking this could be used with a traditional 8.5 flywheel and pressure plate to allow you to run the T-5 with the older motors without having to get a econline bellhousing or use the s10 transmission specifically this would hopefully allow you the option to choose even a v8 style transmission with the right tailshaft like whats provided by MDL. They also are making the transmission mount for a 60-65 Falcon and Comet as well. So this would be perfect setup with a 8 inch to swap into the Comet and allow me to handle the power when i go turbo. Plus better off the line performance with the lower rear gear since i would have OD and id still drop HWY rpm.
1962 Mercury Comet 170 ci, Dagenham Trans, 2.83:1 7.25 rear.

My tri power 200 dd went 14.22 that is 195 hp...Two 9'' clutch plates exploded, no steel pressure plates made...Had a company make me a custom 8.5 steel flywheel that used a 8.5 steel pressure plate...(They said that the European racers used it and it worked for them ) It started slipping before I even got it to the track!
Maybe they did not get the flywheel to clutch clamping distance right, I do not know....After that went turbo and 10.5 clutch and new build I have stepped up to 11''
