Keven, just curious, do you have any idea how many rpms the engine might be turning at 110 mph?

168*Gear Ratio*MPH/Tire Radius
Assuming a 29 inch tall tire, which would probably be around 235/75/R15
168*4.11*110/14.5 came to 5238RPM for me

Yes, I did have a problem with the passenger side frame rail. I just took a cutting torch and notched the frame so that they would fit.
Also to anser the qustion above. My truck runs 4000 rpm at 100mph.

For those of you keeping score of the RPM's, the F250 is going to have a 16" tire size. :-)

[font size="1" color="#FF0000"]LAST EDITED ON 09-Jan-01 AT 04:09 PM (EST)[/font][p]I have no idea about top speed but like they said earlier they haul @$$. My moms 77 F-150 has a 351m with a beefed up cam running on the stock 2 barrel and no other mods and she was clocked doin 93 mph in third gear on the 4 speed, got a free ride home in a cop car. And one day going to work we had a little roll with probably an 86 vette and to be god honest with you we whooped the crap out of it, the guy later came into my moms station and asked whos truck that was and she told him it was hers, and he said he was pushing the vette awfully hard to keep up and it was also on a pretty not so straight stretch of highway, pretty cool :-> . Had a lot of fun in that truck. It's a heck of a scary ride though.

Not only could you have 16 and 16.5 from the factory, but add to the mix other sizes that were "available" such as 17 and 19", but NOT 15....

15" was just brought up to give a tire size. I run 235/75R15's on my truck and for the purpose of making the equation easier to understand for some of our guests I used it since it gives a correct speedometer reading on my truck, since I have a correct tire size now it comes to 4900RPM to go 110.
168*4.11*110/15.5=4900 (31/2, this doesn't count any tire expansion at speed, and assumes the tire is actually the same size it says it is)

I'm with you. In fact, the majority of our "guests" are probably driving an F100 running standard 15" treads! :-) Hopefully, the math lesson will not be lost on them.
