Truck ran much better tonight I put a 1/2 a tank of hi test gas in with the regular gas and changed the oil to 10-30 from straight 30 figuring this was better for the hydraulics and less drag on the internal engine parts.
Maybe my imagination but I think I gained another 10% of power. It loses much less speed on the long highway inclines (dropping for 60 to 55 instead of 60 to 48 on the same hills as last week. I did not notice any misses out the exhaust tonight.
It is running much smoother...not prefect but much better. This could also be a product of the break in as well. I am driving the truck as much as I can.
I will continue to drive it and maybe bring it to my mechanic friend to do a final check/adjust on the valves.
A much happier RB53
