Prothane vs Energy Suspension

[gene_ensor]

I'm curious what the views are regarding Prothane vs Energy Suspension for engine mount inserts, transmission mount, pan hard bar bushings, sway bar bushings, trailing arm bushings, body bushings, and radiator support.

The consensus at other web site forums is Prothane is firmer and less likely to make noise, but causes additional vibration transmitted to the steering wheel over OEM. I am also a firm believer in OEM rubber which has significantly more research dollars into than the aftermarket urethane products. Granted newly purchased OEM rubber will not last as long as the urethane, but it should last longer than I will be able to drive the truck.... for certain applications.

Because I hate squeaky rides or the effort to keep them lubricated, I have already purchased body mounts and a-arm bushings utilizing OEM type rubber. But... am undecided about the other bushings.

The build plan is a BBC 496 with the option for 100-250hp N2 shot ie 650-850 hp at crankshaft. Tremec T56 magnum assuming a kit is available in the next year or two. And other mods to hook ie engine moved back slightly, fuel cell and battery in back, slicks from time to time, DTS dana 60, some after market sheet metal, and trailing arm pivot lowered 6" in a 69 SWB 2wd. Hence I believe I will need some firmer support than OEM designed bushings. I've also procured the BBC clamshell engine mounts/stands from a 73-87 pickup for added safety given the high torque.

The primary use will be a daily driver on nice days, with some strip. Thanks again for your advise.
