I am in the process of that exact swap now. U have to tear out the V6 mounts. Use a cutting
wheel and air chisel to break the rivets holding the V6 mounts to the frame. Installing the V8 mounts are straight formats. I had my old man with an impact gun screwing in the bolts up top of the mounts as I was holding the bolts from the bottom in-between the frame. People have said that u have to remove the lower control arm, that's B.S. There is a gap between lower control arm and the frame. Get a long extension with swivel head and u are "f***king golden" !! I did it with some loc tite. Only had to use three bolts per mount to hold in place. I changed my fuel pump to a 1996 c1500 V8 model and it was easier when the bed is removed.

I left the V-6 frame mounts in place. I simply fabbed two U-shaped steel motor mounts, that bolted right up to the block. Been in use for 10 years with no issues.

Do you have pics of the steel plates you used ? Im looking for the easiest painless way to mount the motor lol.

You will have to use the 96 up fuel pump.

Here's a pic of typical plates. There are many out there, depending on what you want to spend. These plates are used in conjunction with the original "clamshell" mounts from the small block. I'm not sure if your V-6 was equipped with them, but I believe the mounting bolt pattern was the same on either the V-6 or V-8.


I have read here on this site that the plates will need to be clearanced a little to clear a mounting boss cast into the LS engine block. Nothing a grinder can't take care of.
