The Stovebolt Site Forums The Shop Area General Truck Talk what motor?

I just brought home a 1967 c10 shortbox stepside pickup this weekend. It is the base model as it was a work truck for a plumbing company all of its life. I got it started and drove it off and on the trailer. I noticed that I was losing a lot of water and had a milkshake in my oil pan. The block is either cracked or head gasket is blown. As I just hauled this truck out of Montana my guess is cracked block. How do I know what 6cylinder motor I have? The VIN # if that would be any help is CS14J104637. I am going to pull the head and hope that it is just a gasket but I am thinking the worse as the oil is a mess. Also who would be the best to order a goodwrench motor from?

The base 6-cyl. engine in a '67 C10 would have been a 250, though a 292 was available. Look for the engine series ID number stamped on the pad just aft of the distributor.

I have acces to a bare block from a 65 chevy. I think that it is a 250 or 292. It is literally a bare block. But we are in the same state and this might interest you. It would be available for free, my friend bought it years ago to rebuild and put in his 65. Anyways, I hope it is just a head gasket. If you are going to get a goodwrench motor just go to a dealership, or get a "Summit Racing" magazine, they sell a variety of GM crate motors. Good Luck.

All Curt is saying above is true
Do a Quick visual of the engine from above looking down....
If the motor mounts are bolted to the block DIRECTLY ACROSS from one another+ NOT STAGGERED
It is NOT a 292.
2nd DEAD Giveaway,ONLY 292s had the fuel pump BEHIND the Right side motor mount
Good Luck and hope that it is just a head gasket

Be careful. These engines are known to crack in the lifter gallery area & there is no way to repair it. I don,t believe GM supplies the goodwrench engine in the straight 6 anymore. Now might be a good time to put a v-8 in it. The best place to get the Goodwrench engines is from a large dealership that specializes in them. There is no set price on them & the small dealers buy them from the large ones.

This is only my opinion, but I would look at this as an opportunity to build yourself a nicely warmed up 292. Dare to be different. Everybody and their dog has a v-8.

If you need to replace the motor think about how you want to use the truck as you decide which motor.

A 292 might be a good choice, especially if you are going to haul loads around town. If you are going to show it and just run it around unloaded, a 283 would have been a factory option, and one I'd enjoy in a truck like that one today.

Or do what I've done. I dropped a 454 into my '72 over the weekend.... Okay, I confess I dropped it into the bed, but hey, a big block is always fun to drive.

I have figured out that it is a 250. Thanks for the tip about the motor mounts. I have a 350 that is sitting about 5 feet from the truck. I am very tempted to drop it in but I am going to stay the course and restore this truck to original. There are more of them out there that have been changed that I thought I would go factory. When I started the truck and drove it on the trailer I was instantly taken back 28 years to when I was a kid I would drive a truck just like this one to the dairy farmer that I was working for mother's house to feed the calves. My dad would stand in the front yard and chuckle as I would lug it up the road as I wasn't very good at shifting with the worn linkage. Thanks to all for the help. I am in the process of pulling the head and crossing my fingers that it is the head gasket.
