99 FL60 mutt/conversion/repower project build

Might as get this started, so all the related info isn't buried in the less see you trucks thread.. I'll be shifting throw that thread to cross post over here
Due to current ELD mandate of needing electronic logs in the truck by 12/17/17 for vehicles 2000 newer.. and by that time my current mule 07.5 LMM will be pushing 500,000 miles.

Been on the fence for a while either to repower a 90s 3500HD or jump into a full on MD truck.
On 11/7/16 I picked up a 99 fl60 extended cab, with a dt466 engine, Eaton 9sp transmission, 8/15k axles 3.73 gears, HYD brakes, air ride cab, seats and suspension.. 22.5 rims mismatched tires LP up front and 11r22.5 out back.

Come to find out OEM was a 3116 cat, with a 6sp. One of the previous owners swapped a dt466 in.. including an international dash cluster.... Slid a cuttoff chassis on the truck...the dt466 looks natural in the frame, so I'm Wondering if the PO stuck the cab, hood, bumper, then slid the rear frame over a international frame... WB now is pushing 190".. I think the original is 150-160 range

General end goal is something along the following
Mechanically..
ISL9 size engine, completely de emissions, @400/1200- 450/1500 hp/tq with engine retarder
The LMM is ~400/800 at tires so.. ~450/900-950 crank ish extra 3-400tq would definitely run
9/13sp Eaton double OD
air suspension F/R with full manual dump and over inflate capability on both axles
air disc(meritor pan 19, 14.8" disc brakes),
245/70/19.5" H load
9k/17k axles, (lockable diff)
26k/54k gvwr/gcvwr
34-36" top frame height, ( preferred 32" but doubt I'll have enough up travel between bottom of frame and top of axle, it be less than 3" up travel with 10 5/8" common frame size, on rough measurements and 5" axle tube)
170" WB.
100-150 gallons onboard
10 5/8" frame
Body
42" flat top style sleeper, with a proportionately widened/lengthened/raised, pickup truck style cab, keeping the truck under 84" tall preferred less than 78"
Obviously full power windows/locks/seats/mirrors
Heat/cooled seats
Heated mirrors
Keyless entry with remote start
AC/heat with cabin filters
Full HUD display, plus DIC with mechanical gauges

Not to mention P7100 pumps are prone to failure from the same exact things electronic pumps are. Fuel contamination and low supply pressure murders them just the same. Some people hide behind the big bad PEE-PUMP thinking they can neglect them.

Bad fuel would kill any injection system..
Naturally, it would be in my best interest to make sure it is well feed with clean fuel. I'd duplicate the filtration and lift pump setup from my LMM to the MD truck..

Is there a program out there comparable to EFI live for the ISL?

I had a guy buy an S360 I had sitting here, brand new in the box, to put on an 8.3L with a 5.9 injection pump, turned up some....I told them, this isn't wastegated, so you'll need to watch it.

They install, and call me 2 days later...turbo has a broken shaft, we want warranty...I told them I'd talk to borg warner, and let them know. They stopped payment on their credit card, now I'm out a turbo that did not have a warrantyable failure due to truck drivers. $850 down the drain.

Well that sucks, buy good info for me to know

Thats a bummer. The turbo business is the most bittersweet thing I have ever done. Most days I love life but some customers can sure spoil a whole week for me.

The wastegated 62mm borg made for a replacement on the DT466 is a pretty darn good unit on the 8.3 . Just an FYI for you 8.3 guys. :Cheer:

Course these are in reverse order :doh:
 
Any reason not to stay with the 22.5" wheels? Would think tires would be easier to find. But I'm not a trucker, so I could be wrong. Looking forward to seeing your progress.

Weight,
drops frame/truck 4-5"
The GN pin height is maxed out about 38" vertically.. your avg 22.5 is 40-43" tall, trucks frame is 41".. lower the bags too much throws ujoints out and messes up ride quality

225 and 245/70/19.5 are extremely common with class 4/5/6 trucks. Ford 450/550, dodge 4500/5500 and the like chassis trucks, 50/50 on class 6 trucks 650/6500

While they make 245-255/70/22.5 which is mainly used on single/double drop trailer and like.. I have limited dedicated steer/drive tire options compared to 225/70/19.5 and 245/19.5

Another aspect is weight capacity of tire compared to what I'm running.. I have similar issue with the 19.5 and my LMM.. even at the lowest weight rating of 3600(dual)lbs I have 21000lbs of tires on a truck that rarely weighs more than. 13,000lbs, rear end skips like a Mg in bobtail fashion, any slick conditions increases chances of get squirrelly while empty

Same principle applies with 22.5, 6 tires at 5-6000lbs a piece, 30-36k, on a truck that won't weight more than 23k.
You can only let soon much air out to soften ride quality before you risks over heating the tire due to under inflation

I have to admit I love the looks of 19.5's. Just never seen a set that lasted very long. Steer tires always get choppy and they ride pretty rough.
 
I still can't get over the amount of steel he put in that 5th wheel mount. New tall stands would have been cheaper.
 
Pressure washed it.. went hunting for data plates..
