hello all,

first of i'd like to say greetings, and hopefully this will be the first of many beneficial posts for everyone.

I am currently working on a brief history of the domestic manufacturers
diesel light duty-heavy duty pickups 1978-current models, 1/2-1.75 ton(f550/gm 5500/dodge 5500), including, chassis,diffs,tcases,trannies,cabs and spec packages. i have found very little info
regarding these on the net and the books and other publications that I have are limited in regards to these specs.

what i am currently searching for however, is information pertaining to the in-direct injected diesels from 1978-1992 5.7 gm/6.2 gm and naturally aspirated 6.5 gm( i have enough info on the 6.5turbo) as well as the 6.9/7.3na and 7.3 turbo navistar/ford engines and transmissions behind these engines as well as the differentials and transfer cases.

also more importanly since i am a hardcore mopar enthusiast(see sig.) i am also looking for info regarding the 1978 only model year of pickups that contained the 4.0L 243ci mitsubishi i-6 diesel and associated tranny/diff and tcase info, and also what model trucks had this engine as an option.

thanks for the help. more to come.....................

Hi, 78/79 Dodge came with a 4.0 (243") L6 DSL. VIN code 'H'. The engine was a 6DR5 (6DR50A) series Mitsubishi 6. An adaptor ring was used to mate the mitsi block to the Dodge 727 or standard trans. Engine considered 'light duty'
and only offered on 1/2 & 3/4 ton trucks, built at the Warren plant, 3.91 diffs. The little 6DR is relatively high revving & small displacement for a mitsi 6, shares specs & parts with the more common 4DR. Produced 1970-1991, first used in the 3.5-ton T44 Jupiter cab-over truck, then T series truck, Rosa bus, Froklifts, Loaders, Generators agricultural machinery etc. An online parts manual for it's use in the KOBELCO LK300A Loader is available at http://www.kobelcoamerica.com
