Wanted to get an opinion as to what Chevy diesel to drop $ on. Ive got a FJ62, and have Marks Adapters Chevy 350 adapter for my auto. Have heard that this adapter allows for a 6.2/6.5 to work as well. Any insight to these motors for this application? I've had buddies with 6.2's have excellent results, but know that the 6.5 had some "issues". While a Cummins would be great there are a ton of the 6.2/5's out there for little investment, and are easily rebuildable. I've currently got an OME 3" HD lift and planned to add 2" lift shackles for additional lift. If needed I could do a SOA (with removal of spring). Any advice would be highly appreciated. Thanks!
