Took it out for a hiway ride last night. After a real run the guage showed 40 idle in gear. As soon as i moved it went to 80 plus. I've been using Castrol GTX 10/40 not synth. The high pressure bothered me abit but i'm thinking after 2 hrs on the chassis dyno last year and that's not easy on any motor, it didn't hurt it. He only took it up to 4800 rpm because he said my goodrich tires were not rated to go higher. This with 300 gears stock converter.
