I wouldnt normally do this as im a newbie to the site and all but since this is almost the exact question i was gonna ask i will go forth with it. Would the same logic with the motor mounts apply to a 79 olds cutlass supreme. its got a 350 olds in it right now. and my buddy wants me to put in the 454.

The Olds 350 is a great motor. Bore it .068 or .100 over with 400 chevy pistons and rods. You will have 380 cubic inches with small journals and offset grinding. A 455 Olds is also a fairly easy swap.
