Thanks goose
Figure I'd just get the original thread open back up..
~3 years later...
Learned alot with this build/repower.. Good, bad, and holy **** didn't think that would work..
With my LMM is already over 300,000 miles I. Would easily have 400k by Christmas this year on it.. Fwiw I did ~92,000. Miles in 39-40 weeks last year.
Some legislation passed pertaining to CMV, stating anything newer then 2000 needs to have electronic logs, By 2018.
So plan.. Ideally
Rust free 99 older C3500HD.
Possible 97 older doesn't require to have working ABS. (DOT violation)
Repower will be LBZ/6 speed Allison
International ran 1000 series in their 4200 with driveline/parking brake. That will be swapped over the the 455 chassis. Since OEM parking brake is tailshaft mounted, and hub brakes generally suck.. Also working parking brake is a DOT requirement
2wd 4500/5500 kodiaks have tailshaft mounted parking brakes at least 06 variants, got VIN and trans SN numbers off each
Allison will be built (gmax 6 variant) low stall tripple disc TC
Engine will be keyed, aftermarket pistons, possible rods, VVT removed, studed, basically identical to what is in my LMM though with a higher CR of 19:1
On the fence with ovals/round bowls
I have yet to get same loaded MPG as round with ovals. Granted finger designed them with strength being #1, efficiency was bottom of the list.. I honestly don't fault him for that, he has designed a superb product. MPG usually Isn't consider when building a 800+ truck lol
Need something better then stock, with stock like MPG.
Talking 1-2mpg drop from round to oval. Over 100,000 miles from 12 to 10 at 2.50 diesel that's ~$4100.00 increase in fuel cost.. That's ~20k over 500,000 miles.
I have an 06 LBZ donor truck which which I'm hoping to pull alot of electronics of to swap over.
The GM-455 plateform runs a D80 in the back with a 10*7.25 bolt pattern.. likely swap out for newer S110/130 with a 10*225/285mm bolt pattern and have new adapters made for the front. This Allow me to run aluminum rims.
Also will be building a 3 link air ride on the back as well.
