273 to 340 swap

Figuring out the front accessories isn't Rocket Science.
What I'm wondering is why hasn't anyone mentioned the Motor Mount issues that come with a 273 to 340 swap?

Guess I will.

The passenger's side mount will only bolt up with the top 2 ears, the bottom ear is reversed on a 340, which means either welding a spacer to the bracket to attach to the rear lower block ear, or welding a triangle-shaped piece of steel to the rear part of the bracket and drilling a hole for the bolt.

The driver's side requires a spacer off the rear block ear to the mount bracket.
The difference is @ 5/16".

{edit} Lots of mis-information here, I PMed you exactly what issues you'll have. MN.{end edit}

Mark.
