does anybody know where i can find motor mounts to put a 454 in my '67 c-20?

 

what engine does it have now ?i believe the small block chevy mounts work for the big block .i used small block Mount's in a 71 chevelle ss ,when i put a 454 in it and every thing was fine.

 

originaly came with the 283, when my dad owned it he put a 350 in there and thats what i have in there still. never done a motor swap before so im just trying to make shure i figure out what im doin as much as i can before i start so i dont spend weeks dropping it in and pulling it out trying to make adjustments
