97 K1500 5.7 Vortec engine.....but a crate one from GM. Approx 70k on it with Mobil 1 after breaking it in for 5,000 with normal dino juice 5 years ago.
I find it hard to believe that 2 sets of rings right next to each other up and bit it but I'll run a compression test and maybe a leakdown this weekend.
