UR50SLO has been using our TR Poly mounts on the F-body chassis with good results as he stated above. I believe he is welding in the TR frame pads on the crossmember to get it all to fit. This lets him move the motor back some, but is harder for the average person to install.
I am currently working on a bolt-in setup based on the original TTA mounts, with Poly built into them. I am also looking at using a bigger and/or softer Poly bushing to lessen any possible vibrations. They should work great & be able to handle all the power you want to put to it.
As far as solid mounts go, they have been known to crack blocks because there is NO give at all with them. A solid mount will have WAY more vibration and create WAY more stress on the block than a Poly mount would ever have. I had a solid mount on my car at one time, and luckily I just ripped the mount to pieces instead of my block. This was on a daily driven street/strip GN. NO V-6 should EVER have a solid mount on it. If you would ever need more than our Poly mount (not sure how), then a mid motor plate should be used. Maybe at 1600 hp & above?
As for me needing parts to work on this project, I should have a pair of stock mounts & brackets coming soon, so I shouldn't need those.
If ANYONE has a pair of the stock frame pads that are bolted to the crossmember, PLEEEEASE let me know! I really need these to continue designing these & get into production ASAP. I am really trying to get these made & help you all out, but I need a little help here. I will buy, borrow, trade, replace them & return the favor to whoever can help. Being that the mounts are discontinued & people need more DP clearance, I need to get these ready ASAP so people can get back on the road.
Any help would be greatly appreciated!
Thanks-
