[QUOTE="JD3020, post: 1073879, member: 373"] Yes, i keep RPM's high on hills. Hell one day i was racing my brother in his 6.slow, i had our 25ft GN with a Cat 304 mini-ex on it, he had our small trailer with our skid steer. I passed him doing 75, up-hill on a decent grade. IDK what RPM's were but 75mph, 3rd gear(auto), 33" tires, 4.10's. It was screaming. LOL But i highly highly suggest valve springs if you plan on doing that, especially with a D66. Backpressure can get high pretty quick. [/QUOTE]
