been doing some more leg work...
"assuming" marine is similar to OTR setup.
www. tadiesels.com /eng-cummins_6CTA-430.html
seems sweet spot is 1600-2200 rpm.. TAD doesn't know what size turbo is used on their 450/530 hp 8.3. or at least the person I talked to...
from 1600-2200 makes ~1000tq
3.07 gears 245/70/19.5(33") with a RTLO14913A put rpm at 70mph
13th 1590
12th 1890
11th 2200
trans is going to be either
RTLO(F)14913A double OD 1/.86/.73
or
RTOO(F)-14613 triple OD 1/.85/.73/.62
current setup in both trucks, runs a thermal fan clutch.. I know the ISC ran both thermal and on/off air clutch, with as hard as I'm going to be pushing it..... the full engagement of the fan clutch would be welcomed... plus having a manual engagement at idle for better AC efficiency during hot humid days./
question is....does the 6CTA8.3 run the same block as at the caps 24V ISC 8.3? allowing the fan clutchs hubs to be interchangeable?
shrader valve and control isn't that big of a deal... can easily R&D that off a big truck..
pulled this of a salvage yard site..

the donor 93 FL70 runs a HYD clutch
the 99 FL60 runs a mechanical clutch
fl60 run 8 lug 275mm? BC hub pilot.. I haven't call see if I can swap to a common 10 lug.. rotors run a 10 bolt pattern.. at best just a hub swap...
drove the fl70 up and down my 1/2 mile lane... the 275hp 8.3 moves ~13,000 lbs better than the dt466 moves 10,000lbs that's nice
not sure what to do with/for dash gauges. OEM is a 8 hole with 3 each side and 2 3 3/8 center..
racepak IQ3S
autometer gauges
ISSO gauges
thought about quad pack gauges, those usually come in 5" gauges
options?
opinions?
scheid rep got back with me...
head studs, valves, camshaft, valve springs, all available..
butterfly exhaust brake will need valve spring up grades. forgot to ask if a 24V 8.3 head would fit on a 12V 8.3 block...
currently scraping up to buy the transmission.
the radiator will need replaced.
fan clutch be it air or thermal..
all belts hoses
all rubber brake lines are being replaced with SS braided -4 dot lines through frangola

I'm sure there is more on the "to do" list that I haven't remembered/thought of
engine/trans/gear ratio swaps, rebuild the brake system, is the big 4
