 Got a '68 Shark that is essentially a basket case. Came with tons of parts, literally in bushel baskets. Have two pressure plates and three sets of pressure plates and clutches. I am running a 327 with a M22 4speed. Understand there are several possibilities for running this. This ill not be a number correct restoration and I want to be a regular driver. With that, are castsing numbers important for flywheel? How many teeth should the flywheel be What is the best option for the cluch 10 1/2 or 11?Anything obvious I am missing? Thanks for the help!

Casting numbers on the flywheel for your application are not as important as getting one that's for an internally balanced engine. (your 327). IIRC, an 11" clutch was the standard size with a 168 tooth 'wheel. You should double check the size. As far as brand, unless you're planning on beating it, the standard clutch works well and has a minimum of install problems. There are different spline input shafts for the trans, a 10 spline and a 26. Same diameter, so the difference is obvious. The 11" model has more surface than the 10.2, so I'd go with the 11". Just my thinking. |

Thanks Tim. Goes along with what I was thinking. Did a little checking and it is a 168 tooth (no I didn't count them!LOL!) flywheel. Think I'll go with the 11" clutch. Will count my splines but I think it's 10. (I can do that with my fingers! 168 I can't!) |

I think the small blocks used the 10-1/2" clutch and the big blocks used the 11" clutch. The 10-1/2" clutches will stand higher revs without coming apart. I know as I sent an 11" clutch up thru the floor, thru the dashboard, and thru the windshield of my '59 Chevrolet many years ago. The damage to the car (and engine) was extensive. When the clutch exploded it tore the outer edge of my flywheel off and that tore off the back 2" of my block. It also bent my frame on both sides and severed the gas and brake lines. And my bellhousing completely disintegrated. As in completely gone. It blew at about 7000 rpm when I missed my 2nd gear shift. |

Tim - Dude that is like a serious blowout! I've heard tell of that happening to people, but you are the first first hand account! That makes me think twice about which flywheel and clutch to go with! All of a sudden smaller sounds better! Second lesson is don't miss a 2nd gear shift at 7 grand! |
