I have a 00 ext 5.3 with hpp3, free mods, headers, exhaust, t-stat, e-fans, 410 gears, k&n filter, pulleys, traction bars, 20 inch wheels with good year hp 295/40/r20. I went to the track on friday and ran a 15.13 my best time. Some people are telling me i am over geared that i should remove my 410's and install some 373's and i would run faster. Has anyone had any experience with this I would hate to make the expense and get a higher ET. My next mod is the shift kit and corvette servo waiting to be installed.

Thanks for any help!!

 

Stay with the 4.10's. Especially with your wheel/tire combo.

 

my wheel tire combo is the exact same size as the original wheels and tires on this truck. i found that out when i set the tire size to default to find out how off the mileage was and it was dead on the mark.

 

You don't need less gear, you need a high stall converter. Do that and look for some mid 14s with no other mods (traction permitting).

 

But they weigh more. More mass takes more torque to get going.

 

dont run at the track with heavy wheels is your first problem.. second i have 373s and im not changing
them no need to. i have 410s in my stang there great but my trap speed isnt that high et is nice.
as far as 373s i run just fine with mine. but everyone is entilted to their own opinion.. if you have them
already then keep them. youll just need to create more top end so your motor doesnt starve itself
out.

 

id run lighter wheels

 

doooood, why didnt u call me,

and 20's, when did those come in?

how'd the traction bars work?

 

Sup.. David... you should have called.. I really did not have any plans early Friday night. I would just keep the 4.10's. The only reason I don't have them is because I really don't think it feasable going from 3.73 to 4.10. On the other hand had I had 3.42's and had to choose between those, I would have gone with some 4.10's. Are you still hooking me up with some traction bars? I will give a call sometime this week.

 

Hey Daniel i did call about 4 times and your phone was busy and busy, I had no one to go with but i will call you today i need to get the autotap and configure my shift points with the new tires and the 20's

OH i am getting closer to your ET i can predict a race coming on!!

BRING IT ON!!!

I might go this friday with the 50 Dry shot installed
