Gearing/Clutch Chatter BBC-T56

[TMIProducts]

Hello Everyone,

I'm having a problem with my clutch chattering when the clutch and engine are cold. When they aren't it still seems like I have to slip the clutch quite a bit and then I smell hot clutch. It occurred to me this weekend that maybe I have gearing issues.

The engine is a 454 BBC with a T-56 transmission. First gear is 2.66. I haven't touched the rearend, but was told it had something like a 3.09 rearend gear. The Camaro's that this transmission came with usually had a 3.31 or 3.55 rearend. I'm wondering if mine is geared too high. I think the torque of the BBC is overcompensating so its sort of working.

Would this cause my chattering and having to slip the clutch problem? 6th gear is almost useless right now. Doing 80MPH it tachs about 1700RPMS, if that.

Thanks for the help!
