#22300 12/06/2003 10:31 AM | Joined: Dec 2003 Posts: 510 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 510 | I just recently bought a 64 C10 longbed Fleetside with an I6 and granny 4-speed. When I bought it I was under the impression that the motor was a 235. But I've read a lot about 230s and 250s (which I thought were Nova motors...at least I've owned Novas with them) in the C10s and now I'm confused. I'm a little more familiar with smallblock V8s than I6s so I could use a little help. Is there a rule of thumb for which motors were used when? A good way to identify them? Any help would be appreciated, Ray Buck http://www.chevyasylum.com | | |

There appears to be a bypass hose running from the water pump to the thermostst housing. If that is correct you have a 292, big brother to the 230/250. You can check your casting number www.inliners.org. Larry 63 C20 292 daily driver 68 C20 327 soon to be?
I don't own a vehicle that isn't old enough to drink.

The only one I found (right rear side of the block) said K66.
However, based on the facts that I measured the side covers and they're 6" tall and there is a water hose going from the inlet to the water pump, I'm gonna take a flyin leap and presume that it's a 292.
I'll find the casting numbers on a day when I'm not tryin to keep from bein blown into the next county by a storm.
Thanks for everyone's help.
