Do you think it is possible that i have 4. 10 where can i find out i want to make sure i dont have 4. 10's?

105 mph with 410 and stock size tires. I must of got a bad truck. My truck is screaming at 85 mph (1997, 4 x4, 410 gears,5spd, stock size tires). Maybe its my transmission?

:--)

 

[CATCRACKER]

pstillo, that is what i have always heard about the 4. 1 if i knew the 03 would do 105 i might have considered 4. 1. i would like to find out if others w/ 4. 1 can do 105

If the 2003 can break 100 mph with 410. I would have ordered the 410's instead of the 373. I just don't see.

Check out http://www.f-body.org/gears/. Acording to that, Casey's truck should do 111 mph @ 3400 rpms. That is fast enough for me .

Maybe I just got a good one. Maybe the Canadian air is thinner? It was one of the first produced. The tach said 3200 and the speedo said 105. And the speedo accuracy was verified by my GPS. And my gears are 4. 10. I always heard that black trucks are faster then other colors.



Maybe you should take it back to the dealer and tell him it is not running right. How about a paint job?

Casey,



Black trucks only go faster at night when you can't see them. Silver trucks on the other hand... ... .....

I wanna come play!Been dying to run a 03 h. o. from 0 to 85. Just gotta see

I realize this thread relates primarily to 3rd generation trucks, but a similar discussion a while back on the 2nd gennies seemed to indicate they were good for better than 125 with 3. 54 gears before they shut down - I know I took mine up to 110 once on a quick spurt - it was still climbing rapidly, but *I* wasn't!



That was before the Comp, but doubt that changes top speed capability...



Wonder what, besides the differential gearing mighta changed?

Sure. Whatever you say.

thats it i am going to run this thing again with full tank and see where this thing is redlining at. the first run if i remember correctly it would only went to right before the redline and stopped. at top speed it was barely touching the redline. i have seen the needle go way past red while trying to shift fast and my pedal sticking went to 3400. it will not go to 3400 on the top speed though? what might be up with this? i am going to run it again!

 

[Dean Upson]

CC,



Those mosquitoes hitting the windshield could be slowing you down .

I had to say something- In Florida it would be G-d D-m Snowbirds in the 15 seconds before crash. Oh and my 99 loses plastic parts over 110.

 

[MCummings]

CATCRACKER, i'm still sticking with this.



In my truck I can surge to 3,700 RPM and WOT, no load is about 3,550RPM. Mild load will easily pull the motor down to 3,300RPM

'98. 5-'02 Cummins have two different goveners set at different speeds. . Full load, and no load,, No load is 3,500 RPM full load is about 3,100-3,200.



I'm betting the '03's + are the same way.

ran again 108 cant get my truck to go past any red(girl truck). dont worry i am going to make this thing a man

b-1(maybe even a Piers50),injectors,clutch,fueling box,guages



where do i look to find out if i have 4. 10's?

 

[MCummings]

CATCRACKER,,,



The 2nd Gen's had the R&P ratio under the hood along with paint , engine, and transmission codes.



HTH,

Merrick Cummings Jr



EDIT: A gear Vendors, or US Gear Overdrive would solve this situation quickly. We need to find out if the ECM or PCM is limiting MPH. In that case a US Gear or Gear Vendors would only get the RPM lower, but not the speed higher.

Can't remember this for sure but it seems like the ratio is also listed on the sticker in your glovebox!!!!!!!
