Hi Rick, I am no expert, Joe Timney is an expert, but I like the rubber
mountings and I see nothing wrong with four-point rubber mounts as long
as the mountings are fully reliable. I'm using the original Ford rubber
front mounts on my Ardun, and the GM rubber mount under the tailhousing
of my Borg-Warner Super T-10 gearbox. I expect no trouble with any of
these.
Don't know about bracing twixt engine plates, far as I know the rear
plate people use with solid mounts is a flat plate sandwiched between
the bellhousing and the block flange, extending out to the frame, and
any kind of fabricated solid mount to the front block mount points.
Also don't know about suitability of a CV mid-way joint in your Buick
driveshaft for racing, maybe somebody else does. If it was just viewed
as an alternative u-joint, I imagine the rear part of the driveshaft
would have to have a regulation loop around it to contain the shaft if
the CV joint broke, and there again the front half of the driveshaft
probably also needs a loop behind its front u-joint. Despite the
presence of the crossmember tunnel. Dan Warner may say. I think these
loops are a serious safety item, Keith Turk once broke a u-joint and
even with the loop the gearbox tailhousing got hit sideways so hard it
broke and the gearshift lever hit his leg HARD. And it really HURT.
But didn't break his leg. Cheers Bill
