Staright Six Identifiacation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm pretty sure that I've identified the straight 6 in my son's truck, but I'd like to double check it with you guys.

I've included a photo.

As best I can tell the stamp is: 37 127

This should be a: '73-'76 250ci

underneath the 37 127, there is a 'G' next to a larger 'M', directly under the GM is the number '81'

Give me a picture of the side cover. 4 inches tall for a 250 and 6 inches tall for a 292. Fuel pump right behind the dizzy on a 250 and middle of the block on a 292.

Side covers are 4", and fuel pump is right behind the 'dizzy'. I was thinking that this is a 250ci, but now it's nice to know for sure.

Thanks, Guys.

That's the same arrangement as a 230 also, although the fuel pump looks different. But it also looks like someone pump the wrong pump on and had to make it work.

'63MurderTruck · 04-04-2015, 08:26 PM

Anyone know where I can find a decoder for the ID: F0418CCJ?

Like I mentioned earlier in this post, I believe this motor is a '73-'76 250ci, but I'm trying to make sure.

I searched CCJ suffix code and found the link I posted right before your post from Nova resource. I don't know about 292, as the site I pulled CCJ from was a Nova site and the 292 was a truck motor only. However this site lists casting numbers:

What year is it? It looks like the 3 letter suffix codes were only on later engines,
69 or 70 forward. I didn't read this entire thread, but might be helpful to you:

Yep...

250ci made in 1978. Thanks everyone

1978
6-cylinder
C3Y - 250cid
CCH - 250cid w/TH350 and NB2
CCJ - 250cid w/3-speed manual

jdl71 · 04-04-2015, 08:42 PM

I think you really need the casting numbers to be sure because it also shows CCJ for 1976:

1976

6-cylinder
CCC - 250cid w/TH200 and NB2
CCD - 250cid w/3-speed manual and NB2
CCF - 250cid w/TH200
CCL - 250cid
CCJ - 250cid

'63MurderTruck · 04-04-2015, 09:10 PM

Good catch. So... it's a 250ci made in 1976 or 1978.

Thanks again, Everyone
