Chevy 292
 

I picked up a Chevy 292, supposedly from a C60 truck. The block casting number (3921970) and head casting number (3927763). The block casting number indicate that the the engine was manufactured between 1963-1976. The head casting number indicates a manufacturing date between 1967-1972. The crank has 3 dowel pins and it came with a generator, I am guessing that it is most likely from mid '60's.

The block is Chevy orange. The head is a blue/silver.

Ideas why? Replacement head?

When did Chevy use blue/silver for their engines?

When did Chevy convert from generators to alternators?

I think that GM used alternators from 1963 on...a quick visual confirmation of a 292 block are the taller side covers when comparing them to a 250, 230, 215, and 194 blocks.:welcome:

Yes, it is a 292. 6" side covers.

The head is a 65-70 230/250 head with 60cc combustion chambers.:pimp:

Interesting, thank you for the information, Jalopy.

Is there anything I should be concerned with having this head on the 292?

Assuming that the short block is stock, what kind of compression ratio would I be having? I am purely guessing that the original head was probably somewhere in the 76cc range.

Go over to the Inliners forum Inliners International devoted to all Inline powered vehicles and do some searches, the head may bump it up half a point but because of valve shrouding it's not a big performance swap but will work great for everyday driving. :thumbup:

I'm not sure what the differences are in the heads, but years ago i used the original head off of my 1964 nova 194 motor on a 250 motor and it upped the compression. I know some 283 and 307 v8 parts interchange. You'll have to do some research on what parts, because that was twenty years ago that i did that. I used a v8 bell housing and clutch and 4speed from a vega. with the 6's good low tq and low gear from the low gear of the vega tranny, It realy pulled out of the hole in a hurry.
