I am looking into an LS1 swap. I see a lot of gmt400's with those types of swaps. However i am not too familiar with modifying so im currently researching all of that.Use a thicker oil like Castrol synthetic blend and some type of oil treatment as well it just might help good luck.
When you replace the engine look into a GM crate motor or pick up a LS engine with low miles to get the truck to move.
