47 Cadillac 346 cu. in Flat head ---Edmunds intake---Tank motor

I just bought a 27 Ford with this 47' Cadillac 346 Flathead. It has an Edmunds two 2 barrel intake. I heard the 346 was also used in WWII tanks. Does anyone know what kind on tank? And the Edmunds intake, the air cleaner lids say Edmunds Custom. Is this a rare intake? Any info would be great.

 

Lets see the rest of the car. The engine looks pretty tidy. Nice score.

 

wow that distributor sticks way out there

 

GM engines were used in many military vehicles, tanks, weapons carriers, self-propelled guns, bridge carriers, and so on.

 

The intakes for the flathead caddy's are hard to find & harder to pay for. The air cleaners are the re-pops, based on the filter I see.Looks like a nice clean setup tho.Now drive it.

 

You don't see those old Cad motor's everyday! Didn't the old Sherman tank have a 346 Cad engine?

The original Shermans had a nine cylinder air cooled radial aircraft engine that sat right behind the driver (inside the passenger compartment). But there were plenty of other tank designs, many of which did use the flat head engines.

 

Don't think Sherman's ever used caddy engines:

However the M5 and M 24 light tank and the M8 selfpropelled Howitzer used 2 caddys each with hydramatic transmissions.

I built a T27 with a Stuart motor, then sold it. Now finished by a new owner, just search my older posts. http://www.jalopyjournal.com/forum/showthread.php?t=251816&highlight=kangas

 

What tranny are you running and could we some pic's of the whole car since it looks so good in one pic.
Thanks, Russ.

 

First thing you should do is take that boat anchor out,and replace it with a 350 or something. Looks like too nice of a car for that heavy old motor!

Please post some pics of the rest of the car. And oh... I'll be by to get that heavy ass boat achor out of your way!

 

Here's the rest of the car, All steel car, 39' Lasalle 3 speed, 40 Ford dropped axle with hydraulic drums

 

AND the interior

 

The Granatelli brothers sold them from army surplus in 1947.

 

Thanks for all the info on the motor guys! here's the underside

 

Very nice!

 

its a cool car
i saw it at good guys a few years ago
you said that you just bought it but now i see it for sale in the classified section
what gives
tk

 

I actually traded a car that I was trying to sell... 64 Impala with very low miles, it was also listed on here, Marina Blue with an off white roof. Sooner or later i'm gonna need to see some cash instead of trading all the time

 

These motors occasionally turn up IN THE ORIGINAL MILITARY CRATES overseas.
A couple of years ago I had a line on a pair...in North Aferica....$800 each in the crates. $4000 each to get them back home killed the deal.

Nice ride.

man that car is a beauty nice trade lol

 

In my Cad tank engine there were blueprint measures, overhauling measures, and rebuilding dates stamped in a riveted metal tag. The date said something like 1944, pretty cool.

 

m5 stuart tanks. 2 engines, 1 for each track, Cadillac Flatheads are awesome.

 

Great looking ride and this whole article is a world of informtion. Thanks for all the pictures history of the car and of the Cad motors.
