Bob,We notched the crossmember in my wife's 6 race car, as we were concerned
about engine movement with stock type mounts as well. I just sectioned about
1/2" of the tube and welded a piece of 1/8" strap across the opening. I don't
have a pic handy, but if you need one, let me know and I'll send one this
evening.

Hi,
After I got my frame straightened last year, I've noticed that the clearance
between the ATI harmonic dampener and the front cross member and the steering
rack seems tighter than what I previously had. Granted how much metal had been
bent in the crash, I'm not surprised.
So, I have a question for the hive - to compensate, I plan to push the engine
back a tad, maybe 1/4" or so using the "usual method" of installing a metal
plate in the engine mount to frame interface. The question: in moving the
engine back in small increments, will I have to "shorten" the driveshaft or is
the driveshaft length (stock driveshaft and stock 4-speed TR6 transmission)
already able to compensate for moving the engine back.
I'm not planning to go wild and make the car "mid-engined". I'm just looking to
compensate for some "rearranged metal" in the front of the car. That and I also
had to switch back to "stock" rubber motor mounts as opposed to the HD units
that TRF used to sell. Else, if there's a source for stiffer stock-type TR6
engine mounts, I'm all ears. The softer stock units allow a LOT of motion in
both axis of motion.
After two broken cranks this season and reviewing my in-car vids, it looks like
I'm not abusing the self-imposed redline of 6000 except occasional hell-toe
blips on downshifts (Hi Christian!!) that I need to smooth out. But I think the
crank is hitting the frame while spinning and that's adding more stress to the
snout of the crank.
TIA
