LS Engine Mounts in 1966 K10
Does anyone know which mounts to use for a 5.3L LS in a 1966 GMC K10 chassis?
The more dig, I think my truck is a GMC chassis because it has the 305 V6 with factory riveted engine mounts towards the front of the block. |

The frame rails are going to be the same, you just need to get the typical mounts for fitting an LS to the chassis. You will need to remove the GMC V6 frame stands and replace them with whatever the LS needs

My truck does not appear to have the same crossmember that the 2WD trucks have. That crossmember looks to be where the pedestals land…

Oh right, my bad! I completely forgot that the 4wd trucks have different crossmembers. Hopefully someone who has already done an LS swap on a 4wd will chime in
