Seagrave V12 Powaaaaah: 1951 Plymouth Suburban

If anybody ever says to you “my Suburban is a real gas guzzler”, I suggest you buy this car so that you can respond “no…MY Suburban is a real gas guzzler!” This next car isn’t the Suburban you typically think of..this is a ’51 Plymouth Suburban, but the original engine is holding a boat in place somewhere and instead it is “powered” by a Seagrave 7.6 liter V12, which is the descendent of the V12 that powered 1933 Pierce-Arrow. With 462 cubic inches of displacement and twin plugs per cylinder you might expect something more than the 185 gross horsepower…but you won’t get it. Expect a boat load of torques and a fuel bill the size of the GDP of several Latin American nations. Find this 1951 Plymouth Suburban offered for $9,500 in Murrieta, CA via eBay. Tip from Hugh.
