1984 K30 454, new motor mounts to big ?
 

I ordered new mounts for everything (trans,engine etc...)from summit, double checked the part numbers with summit on the phone, shows to be the correct ones.
The rubber insert mounts for the old ones are 4 inch’s wide the new ones are 4 1/2 inches. I call them the clam shell mounts. No way I’m getting the new 4 1/2 ones in that 4 inch clam shell. What’s up? Any help is appreciated

ran in to the same problem .

you have a "
NON factory combo .

you need sbc engine mount inserts .

the true bbc ones are bigger than the rest of them .

Must of been a 350 at some point I guess. I wonder if those 350 mounts will be OK with a 450HP big block? The bigger mounts will not work unless I change out the motor mount mounting brackets I’m guessing...

IMO the small block mounts will be just fine.
