I have a single disk ceramic, I wish I went organic. That thing holds the power though... But holy crap is it a pain to take off with sometimes. It is VERY grabby to where I sometimes chirp the tires taking off or it seems like I can't drive a manual. I do know it can take any beatings I put it through though.
Yeah, I guess it's about trade-offs, eh? Thanks for your honest review on the ceramic clutch disc you have. That pretty much lines up with the things I've heard about them, so I guess what I've been told was fairly accurate. I appreciate your input on that.
The 3.55 is kind of "no-man's-land" for gears. It's typically too deep for guys wanting to run highway speeds without an overdrive and too short for double overdrives in T56s..
Tom, it also depends on the rear tire height that's chosen. A 30" rear tire height is going to create a much different engine [email protected]
given MPH on the highway than a 26" or 27" tire height will given the same rear gear ratio. I've found this online tool to be very useful for determining that....(you can even type in O/D if you know exactly what the O/D ratio is in the trans in question).....

Ya know, for some reason these GM A-body cars really vary when it comes to body/chassis dimensions. Maybe it's due to them being manufactured a half centiry ago, and the floor boards sagging. I don't know. But your claim above reminds of how I had such a tough time installing the TCI TH400 in my 70 Chevelle. It wouldn't fit!!! And although my trans is a racing piece with a transbrake, and manual reverse pattern valve body, as far as I know, the case itself if factory GM with stock dimensions.
I thought I would have to beat the trans tunnel up with a sledgehammer, when I had the car on my brother's lift. But my brother had an idea that we used: He cut a 2X4 piece of lumber to the length we needed, and stodd it up underneath the trans tunnel, while I lowered the car slowly downward with the lift, using the weight of the car to tweak the tunnel and floor board in order to make enough room for the TH400 trance to fit without making contact with the tunnel. t worked nice, but I was very surprised that I had to resort to those measures just to get a standard factory TH400 case to fit, when these cars were available from the factory with TH400's. And yet some guys here didn't have any problems even installing 4L80E's in these cars.
The same goes for the trouble I had installing the tall deck block 632 cid engine I have into my car. I had to cut the frame to get the oil pan to fit while another guy who used to be on here installed the same engine into his Chevelle with the same oil pan, and he didn't have to cut the frame. So for some reason the chassis/frame/body dimensions can vary on these cars.
