 Does or did any kit include, or is there an aftermarket kit available for the Detroit Diesel 6v-71 engine??  I have two projects coming up that will require the 6v-71 to replicate them accurately. Would it be possible to convert the 8v-71 to the 6v-71 by shortening the block on the old standby AMT 8v-71 and swapping around a few parts??  Thanks for any tips!!

Nobody that I know of offers a 6V71 in resin or plastic. The only V6 that is available is the 6V92TA from Auslowe.
Your best bet would be to shorten the block, valve covers & exhaust manafolds by one cylinder

Thanks for the quick reply!! I am not all too familiar with the intricacies of truck engines all too much!!
What is the visible difference between the 6v-71 and 6v-92TA?? I'd go for the 6v-92TA if there is not too much of a noticeable difference between the two!!
My last resort would be to cut down the block on the AMT engine if there is a noticeable difference between the two engines. How much would need to be removed from the block to make it look like a 6v-71??
THANKS AGAIN for the HELP!!

Well, the 6V71 is a Series 71 7.0L 210HP V6 with a blower on the top, while the 6V92TA is a Series 92 with an aftercooled tubrocharger the goes to the blower. The Series 92 is a newer engine that was interduced in 1974, while the Series 71 was introduced in the mid-1950s. The series 71 & Series 92 also have different shaped valve covers. en.wikipedia.org/wiki/Detroit_Diesel_Series_71en.wikipedia.org/wiki/Detroit_Diesel_Series_92As for how much to take out, well, I'm not an expert on these things (as I've never done it), but use the exhaust manafold to determine where the center of each cylinder is, then by knowing where the centers are you can deternine how wide each cyliner is and cut one out. You'l have to shorten the exhaust manafolds & cylinder heads as well, and you'll probably want to slice the valve covers so you don't loose the "Detroit Diesel" that is stamped on the top. That's how I'd do it (never having done it before!) |

Hi guys That step by step presentation is grate. That is the same way I did my first one. Just cut out two cylinders from the V8. But you can buy a 6V-71 turbocharged DD by Sourcraut. And it has the right cylinder head covers. You just have to drop away the turbo and to rework the exhaust manifolds a bit. Look here sourkrautsmodeltrucks.com/?page_id=3&category=5So long Arnd |

Unfortunately, it shows as sold out!  Hopefully they will get some more in stock soon! For the mean time, I'll try out one of the modifications, and hopefully if the kit ever becomes available, I'll grab one for my next project that is quite off in the future, as I don't have the time just yet to dedicate to it! |

A few notes on the rocker covers. The AMT K.W. 100 has the Turboed 8V-71 and the correct covers to do the 6V turbo. The AMT American La France kits have a non Turbo 8V-92 with the correct Detriot Diesel covers and the as do the AMT General, Bison, Astro and Titan 90. It also is easy todo a 6V-53 or a 12 or 16v from them. Paul 12V71  16V92  |

That's strange. I always thought the American-LaFrance, Titan, & Astro had the 8V71N while the General & Bison has the 8V92N.

That's strange. I always thought the American-LaFrance, Titan, & Astro had the 8V71N while the General & Bison has the 8V92N. The Rocker covers on the ALF are the tall covers and it has the low profile super charger, air intake and accessories location which make it an L or N. The Titan and Astro covers have the mid production hold downs and are not true N /L series because of the Air intake and taller supercharger. The one in the K.W. 100 is a T series but also has the lower Supercharger and different accessories. The one in my I.H. Transtar Wrecker is in a class by it self, alot of mixed series parts. Some of which look similar to the boat engines and gen. set units. I've found to to a true 6V or 8V you really need to sit down with all of AMTs Detroits and photos and combine the correct parts from all the Detroits. Paul |
