what kind of speeds do you guys run on the highway? I can only go about 65 without feeling incomfortable about the rpms. I do have 4:10 gears but is that normal??

 

I max out at about 3000 rpm going about 90 mph with stock gov. spring.

 

I think I got up to 95-100 range and normally cruise at 65-75 with 3.55 gears and O.D.

 

The way these things handle, or maybe its just mine, I dont like the feeling at 80mph. Still fun though =D

 

90 is about as fast as i like to go and only for a short time. That is only because the motorl is screaming, handling wise it feels comfortable.

 

My will run a little over 90 with 3.55 and I ran it at 80 mph for 1198 miles with no problem.

 

These engines are governed. Unless the govenor has been modified it will allow only about 2900 RPM. The engine will run against a stock govenor all day with the only damage being to your wallet for fuel. I have the 4:10 gears and run 70-75 for extended periods regularly.

 

i had 410 gears in mine and doin 80 it was screaming. i didnt like that or the bad fuel econamy so i took the 3:54 gears out of my parts truck and that helped me out lots....... until i put pod's in it

 

Smooth as glass into the tripple digets. Too bad the roads up here aren't better.

 

I hit about 80 in mine and it was shaking pretty bad that it was scary.

 

I hit 95 no problem and could've gone some more but the girlfriend was getting nervous so I slowed down to the 55MPH speed limit. Besides, I live on a rock in the middle of the Pacific Ocean. I run out of road before I can reach max speed.

Aloha,

If I hit 85, my dash shakes so bad the cd player shuts off.

 

I could hit 96 MPH when I was completely stock. Thats with 3.55's and Over drive.

Now I can bury the speedometer

I never had any problems with shaking, just the wind resistance.

 

I had her to just a few over 100 once for mile or two and like ofcmarc, it was nice and smoooth.

 

x2, we have had a couple of case/ih tractors with the same engine. run 2500 rpm from sun up to sun down.
