I saw that giant at the Chryseler Museum in Auburn Hills, MI. What a beast - my favorite piece in the museum. Unfortunately, I think the museum is now closed to the public (except for $pecial Event$) due to budgetary constraints. I thought doing maintenance on that engine under battlefield conditions would not have been fun.

In case you can't tell by the picture, it has five flathead inline automotive engines grafted together.

Not the best article I have on this beast, but the only one I can find right now. note that there is NO common crank, but the 5 separate shafts are coupled by a gear system on the flywheel end of the engines. The pictures and diagrams in this article show how it was done. How heavy? Very ! Multi-Bank weighed a considerable 5244 lb (2384kg). http://www.autospeed.com/cms/A_112613/article.html regards,Rod

7,500 tanks... that's 37,500 engines!
They were big blocks too... 250 cubes a piece.
I can understand the Poms admiring its complexity. The war also saw Buick Century engines used in submarines, Caddy V8s in searchlight batteries. Chrysler made Weapons Carriers as well, one of which was made famous by Eldred Norman.

I think PT boats used 3 Packards. This tank motor is a monster. Wouldn't it be fun to have one at Bonneville and just play with gears? Top RPM maybe 1600-2000?

The Packard engines used in PT boats weren't derived from car engines...
They were the 4M-2500 V12 of 2490 cubic inches, they were a fresh design in the late twenties with four valves per cylinder and NOT related to the Liberty or Merlin engines built by Packard.
1500bhp is quoted for later developments. Quinton would have been pleased with this.

By the way, nobody commented on the 'Quinton' line I posted...
