Didn't realize the requirements changed for gas engines as well. I put 120,000 miles on that truck with a high torque tune and a lot of towing near gvwr on M1 with no issues. I would need some good evidence against it to not run it in my gasser... But I'm open to Pennzoil or royal purple.

They are definitely salvageable, but the expense is within $20 of a new set of lighter forged con-rods. UPGRADE!!! I guess I'm down to only having the stock bare block (bored .020 over), bare heads, and crank (with grind).
I also picked up the 4.2L Torque converter - should stall a bit higher than the stock 1600 V8 converter
