6v71 info

[Eric Kahn]

Auto transmission cost more than the engine to fix, make sure the transmission is good if it is an allison

You should get more power and much more torque. The 8v71 is also known as the 318 Detroit. That means it's supposed to have 318 horsepower, but compared to 4 cycle, I don't think it feels like you have as much power. Got to keep 'em wound up the governor all the time to keep 'em moving.

Thay seem to all be 730 and 731's I am not sure if I like the electronic part or not.

Detriot "V's"

I have a 61 GMC Cracker Box i'm in the process (like 8 years now ) of stretching the frame for . . get this a 16 v71 i found at a quarry near buy. thing is a monster. gonna put an allison behind it w/ air ride suspension and just play w/ it . might even put a deck on it and haul my ram w/ it.

not sure of the hp rating but i think the tq was in the 2500 ft lb

range it was a motor from a earth mover. still sitting there waiting for me to pick it up. one day when time is avail. i'll get picks.

The tractor is a sleeper version but the motor will still stick out the rear of the cab at least 5' it orig. had a 6v71 w/ a r-960 10

spd and 4. 44 gears Should be fun if i ever finish it.

proram thast my kinda idea / truck ha. . i love the old cabovers ha especially if the engine sticks out from the cab . gotta love that ... you kinda got the idea i bought two 6v92 silver engines with a similar idea to eventaually bolt em together make a 12v92 with a 740 allison in something heheh i have a few trucks in my area that are nice bee homes ha i've been eyeing them a 70's pete cabover , a ? somethink in farm field thats old kinda looks liek a old lj mack from the distance i see it it from ie 1/4 from the road etc. . some day like you said. . the gravel mine i used to work at used to have 2 old 992 the old old style early 70's late 60s etc with 12cyl i think it was a 3412 it may have even been a 16v??. . any how they got cut up fro scrap the only part left is the front half with lift arms and cylinder hehe would make a sick log splitter ha

oh well

"V"'s

Deo, the only thing better is if the Cracker box was a day cab. that thing would've stuck out a mile

I have a pic floating around of a guy who was running a mid 80's pete conv. w/ the hood strecthed a full 4' and he was running a 16 V71 w/ 4 turbos!! the cab was chopped 8" also he had 2 hyd lift cyl and a hyd system just to lift the hood. it was red, orange and white. he said he ran up and down the east coast. (this was a few years ago though) he also said it didnt like much RPM... Wonder why... if ya come across a mid 70's pete day cab cabover gimme a shout. . looking for one to haul our show trucks. . 44 Pete, 65 narrow nose, and a 78 big hood, all w/ cummins except the big hood( very worked 3408

V-8 cat w/ a 5 and 4 behind it.

I always thought the 6v53 detroit was the 318, it is 318 cubic inches

Detriots

Will, times the number of cyl's times the cu. per cyl. will get you the displacement, but detriot named there engines acording to

hp ratings instead. (like cummins engines up to the electronic ones) ie; a 318 is actually an 8v71, a 238 is a inline 6-71

Deo, (therabbittree) can prob. fill yopu in on some other particulaers too. my V6 -71 was rated at 230 hp and so on.





Hope this helps a little, Scott
