My MB will take the needle around to vertical with no effort, my M-38A1 will wind the speedometer all the way around to 0. Not an every day occurance, but the power is there. Both are stock. Others complain their Jeeps top out at 45. They need to have a ride in a real Jeep, and nobody can tune a Jeep like GI Joe here. I have never had a Jeep that would not get up and go. A well tuned 50s CJ-5 would also reach 85MPH. I may be bragging a little, but I can back it up.

The key to top performance is to have the vehicle in 100% factory spec, no shakes, shimmys, howling gears, knocks or vibrations.
This is not possible with the advice coming from the Jeep Peeper sites. There is no advice from professionally trained Civilian and Military technicians. The new Jeep owner gets a lot of half baked input from well meaning newbies and some who post a pic or two from a manual but with little exposure to the actual vehicle. The real experts are not contributing. Lawrence Nabholtz was the best source, he is gone now.
What is needed are more in depth and factual publications similar in content to those by Fred Coldwell.
