In the process of adding a bbk catted h pipe in place of my bbk o/r h pipe.

I got a better look on what could possibly be the OEM motor mounts. They have a bunch of cracks. Does this warrant replacing?

Thank you.

If you jack the engine up do they separate? About the only stock replacement brand left is Anchor. I run them on my Coupe with a 331 and have zero issues.

It would suck to have to replace them later down the road being you are already under the car. If you decide to replace them you might consider the trans mount and trans mount crossmember bushings. I run a Prothane trans mount and Prothane cross member bushings.

I'm debating on using energy suspension motor mounts when I replace them. I see LMR sells a OEM style transmission mount. Might not be best to run two different kinds of material though?

The Energy Suspension motor mounts are top notch. If you plan on doing the trans mount, I highly recommend installing poly on the crossmember bushings. It really tightens everything up, the NVH increase is barely perceptible.

I run the ES poly engine mounts with an NOS trans mount. I had poly, but had way too much vibration at the shifter so i went back to rubber on the trans mount. I like this setup a lot.

The ES poly mounts are the convertible style mounts. The prothane ones are the 87-90 hardtop style mounts.

I tried the anchor mounts, but wasn't happy with how they fit. I had to slot the bolt holes just to get them bolted up to the engine. They are really the only game in town, and are sold under 50 different brands depending on where you look. What's funny is LMR states this as well but then prices them out at $75/pair when they go for $8-10 or so each on Rockauto

I was wondering if that setup would work! Because I was also debating on the ES motor mounts with stock style transmission mount, which LMR sells. Did you replace the cross member bushings?

I’m running the Stifflers X-member so those bushings are poly or maybe even delrin.

I had the ES trans mount as well and ended up removing that for a stock style rubber
