WTB 1990 ZR1 motor mounts polyurethene
 

Does any one know where to get 1990 ZR1 polyurethene motor mounts. Tried Rippie, White, Jeggs, Summit Racing and Energy Suspension to no avail.

The ZR-1 has a very unique motor mount (Oil filled I believe) and I don't know of any after market replacement. I would seach out an OEM. The ZR-1 has no transmission mount, the transmission bolts directly to the C-beam.

I know LT4s used the same motor mount but I havent seen anything but stock set ups.

Phrogs, are you sure that an LT4 is the same mount? Also with the adapter mounting plate, can the motor be mounted an inch further back?

i believe if you tried doing that you would have to modify the c beam as it wouldnt mount up if you moved it back an 1in

yep im sure check this thread for photos of a LT-1 LT-4 motor mount.

as for moving the engine back and inch anything can be done but the motor mounts bolt into the engine k-frame so it would have to be a mod to the engine brackets on the engine I think. then the C-beam like tim said that would need moded as well.
