Hello! Curious if anyone has any experience or recommendations on urethane motor mounts in a 67 with a SBF. My 347 is together and nearly ready to install. I’m starting to get concerned that the combination of 450 HP & 450 TQ and the TKX 5 spd might be hard on the OE style rubber mounts.
I found the Prothane mounts but the reviews say that they will raise the engine in the car about an inch. Hood clearsnce is already an issue. This is one place I don’t need an extra inch.
I installed the Prothane mounts on my '69 with a 351 and I did notice the engine moved up about an inch. Take my completely difference application fwiw, but I would trust their warning.
On the NVH side of the equation, I honestly couldn’t tell the difference between poly and stock.
We’re running a pretty similar power to weight ratio, so I can promise you’re going to have fun with an engine producing those numbers in your car!
