I found my engine code finally! It ends with the suffix "DN".. According to one site that makes it a 1968 307 ( http://www.chevy-camaro.com/chevy-ca...s.asp?group=10 )

On other sites it runs as a 327.. I am totally new to this so please forgive my ignorance on the subject matter.. With that said, just surfing around the internet, the smallest V-8 available on a 1968 Camaro was a 327. (Once again, this is from the info I could find on the internet)

Also, in the link I provided above, the side notes says manual transmission with a H.D. CLutch and my car is an automatic (2 speed 'Glide which codes out as a '68)

The motor was rebuilt and bored over .30, and the casting numbers on the heads put those as '62-'64 small block Chevy heads so it looks as though the heads were swpped at one point.

I would love to positively identify this motor. Any suggestions?

 

this site says it could be a 59 283 in a full size, or 67 283 or a 68 307 in a Chevelle, the casting numbers might help more? Remember that the 307 had the same block as the 283 with the 327 crank
