4.10 gears Eaton E-locker in the front, Eaton Limited-Slip in the rear

Well in that case if those are the true mods then it seems will make your truck drop 2 tenths over a normal radix since he has head work and none of the radix guys on here have that. Thats not very impressive but Im sure it has more in it. Wonder how much more boost it can feed that 6.0 efficiently

 

Reading his mods I'm not real impressed,212/218 Compcam,ported 317 heads,Dynatech headers with a catback,all wheel drive and 4.10 gears.A 6.0 regular cab with those mods alone should be in the high 12s without the supercharger.

 

hows it weighing in at 5,000 pounds that seems really high or no ?

 

it does seem high, especially regular cab, but it has been converted to 4wd. I'm a ecsb 4wd and weigh in at 5650 with the 80e. He has he 60e and is a rc. 600lbs less isn't unreasonable I guess.

 

it must be hard to convert to a awd from a 2wd

 

I have never weighed my truck but, it should be in the 5300-5500lb range with me in it from what I've read. That seems inline with what Dewey just said also. Take the extended cab section out and I could see it in the 5000lb range.

 

Just to clarify, the truck started its life as a Z-71 (4x4) and was converted to all wheel drive by means of swapping out the transfer case. It weighs a verified 5000 lbs and STILL 60 foots in sub 1.6 seconds.

Also, this truck still has a stock throttle body which is a known restriction in the setup (a substantial vacuum has been measured behind between the TB and SC inlet which is very bad in a SC setup), and all runs were made on 94 octane pump gas. I also believe Matt still has the original injectors from the Magnuson kit and might also be limiting him. I remember those to be a concern when he was at the track...

It may not have the quickest 1/4 mile ETs (yet), but when the light turns green this truck has the power to leave the majority of the cars at the line wondering what the #@!! just happened.

There are several upgrades to the truck planned/in-progress this year as he's always changing things.

 

are you a friend of Matt's? welcome to the site btw

I can see the stock TB as a very significant factor here

 

THIS IS the BIGGEST reason I don't talk smack. Hell 13 seconds in a truck is damn fast. Seems lately with all these break throughs in truck 1/4 mile slips we see it has come customary to see ecsb's in the mid 12's....it's hauling *** however you look at it. Nice solid stockish setup and times for 8psi.

Curious...why the AWD convert? What was to gain from dropping the 4wd T-case and going with the AWD case?

I like it, 12.2 and I'd never do another upgrade. I swear.
