Yeah Im gonna stick with leaving the engine how it is since theres no lifter tick, oil use or poor throttle response. I feel lucky to have a shelter kept pickup with no common issues. I do have ideas to lower the suspension 2 -2 1/2 inches and installing a front sway bar with some sporty handling wheels/tires. IN THE END, I'd like to see the DOHC swapped from a 4G63T and with any luck, enjoy it for years to come.
