/6 in a Ramcharger???
yes the slant 6 has torque, but its also a very crappy truck engine, works great in small cars such as A bodies but thats about where it ends
can you imagine driving a 3 ton dump truck with a slant!
Dumptrucks generally had a NP435 4-Speed or NP540 5-Speed transmission with 4.88 ratio Gears and a Dana 70 Rear Axle. (D/W500+ trucks usually had a Rockwell Rear Axle, those gear ratios were in the 5.xx and 6.xx range. Sometimes they had 2-Speed Rear Axles)
Gear Ratios in the Transmissions are
NP435
1st : 6.68 : 1
2nd : 3.34 : 1
3rd : 1.66 : 1
4th : 1 : 1
Reverse : 8.26 : 1
NP540
1st : 7.33 : 1
2nd : 4:38 : 1
3rd : 2.61 : 1
4th : 1.59 : 1
5th : 1 : 1 OR .82 Overdrive
Reverse : 7.81 : 1
With those ratios, and 4.88 gears in the rear, it wouldn't matter if it had a Briggs & Stratton lawn mower engine under the hood. It'd drag mountains across the country, granted at a top speed of about 70mph. LOL
My '75 D300 Dumptruck has a 318 / NP435 / Dana 70 with 4.88's, bone stock 318, with a Carter BBD 2BBL and 2.25" Single Exhaust. It'll go toe to toe with a stock diesel in terms of pulling power off idle.
Used it to "remove" a cab mount from a truck in the junkyard once (bought the cab, couldn't get the last bolt out) So I chained the junk truck to a tree, chained the cab mount to the back of the D300, slapped it into 1st gear, gave er some gas and dropped the clutch... Ripped the frame in half behind the cab mount on the junk truck.
