WOW! What a find.
Looks to be pretty decent.
How far away did it come from?

A lot of folks have heard about the 702 twin 6, but very few know about the 637 Magnum V8.
The 637 replace the 702 twin 6 in 1966.

I have one in a 67 GMC COE fire ladder truck.
About 15,000 miles on it and it runs great.
Sucks gas like there is no tomorrow.

Parts are hard to find.
Fuel pump quit on me a few years ago and cannot be found anywhere.
Mounts on the front top of the motor and has about a 14 inch reach arm on it.
Ended up mounting an electric fuel pump at the tank.

The pictures and story here.

Great Story on the Fire Truck purchase! Would you mind posting a close up photo of the V8 emblem I see on the front, Thanks.

Rod, a friend of mine told me about it. It had been on Craigslist awhile back and it never sold. It came up again and I jumped on it. Came out of Colville WA and before that Idaho. Here is a picture of the emblem.

I also picked up a 637 this spring out of California. I got it freed up, but haven't got it running yet. I also got two emblems with the engine from California. Good to have the extra parts.
