I am building a 83 olds cutlass---what factory mounts will work to bolt in the CHEVY 350??
The frame has several bolt patterns on it. Any other input on motor mounts is greatly appreciated,Thanks

Any mounts for a 350 metric car will work. If your rules let you run solid mounts, they will transfer the engine torque to the frame,wouln't break from the constant stress and keep the engine in the car in a roll-over much better than the rubber mounts. Any proformance shop should have the solid mounts.

I have used both solid and rubber. I haven't
really noticed any difference in the handling of the car between the two. Everytime I pulled the motor
after having solid mounts, they are always bent. This is most likely due to wrecks.

avila what are you using? we use afco solid mounts on our mods and can destroy the car before the motor mounts bend. we have not had anyproblems
a guy at our track had some cheap ones and he hit the wall and his motor wen threw the radiator.

there is only one set of holes the chevy frame mounts will bolt to 2 on to and one on bottom putting nuts on bolts is another story if your fuel lines are out of crossmember and springs/spindles are off easier to get something on the nuts.

Might sound redneck like, but I had the same problem when I took the v-6 out of my Buick last year and put in the Chevy 350. I actually cut some 4" channel iron 3" wide, drilled a 1/2" hole on both ends for the motor mount bolts to go through, bolted the channel to my mounts that were on the 350 and sat the engine and trans in the car. I hooked up the transmission mount,(so it would line up) leveled the engine and welded the channel iron to the cross-member.(flat side down) Make sure its welded good. Be Safe. After a season and a half they were still in good shape when I stripped the car. Make sure your motor is setting low in the car before you weld it. I welded mine with the engine in the car so I could tell.
