I confirmed this. The front poly mount is totally melted due to how close it is to the custom manifold. I plan on swapping in my JWT dogbone (when I locate it!
) with some added heat wrap protection. I don't believe a poly mount will work w/o melting in the dogbone. Hopefully, the JWT rubber has a much higher melting point ...anybody know those melting points - poly v. solid rubber?
I may be forced to run a solid dogbone vibrator...can also get the manifold/dp swain coated in some white lightening which I was debating doing on this car too anyways.
The rear mount looks fine however the slop from the front dogbone AND a noticeable amount from the bushings in the crossmember, I was able to move the engine more than an inch! Glad I bought the aluminum/delrin crossmember bushing combo from Charlie (UNISA JECS)...will also help.
