However, I can't seem to identify the motor. It is a V8 with high performance heads (the ones with the double humps on the ends...), headers, old rotten glass packs, and a 600 cfm holley 4 barrel carb. The old owner said that the motor was a 350, but a friend of mine told me the harmonic balancer was too small for a 350. He said it was more likely that the motor was a 327 or a 283. The 283 was the only V8 offered in 61, so i'm hoping that its the motor in my truck. I need to know how to id the motor so i can rebuild it. Any hints or tips as to how i can do this would be greatly appreciated.

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

There are two usual spots, a casting number of the back of the engine drivers side. Then a set of numbers on the passenger front of the block. They are on the flat ledge of the block just infront of the head. You might have to move the generator to see them(depend's) Then use the Mortec hyperlink to identify. | | | | | Joined: Feb 2011 Posts: 42 New Guy | | New Guy Joined: Feb 2011 Posts: 42 | Thanks for the help. I haven't found anything yet, but the truck is still in one piece. (a frame off restoration will start soon, so i'll be able to get a real good look at the motor. Any other tips anybody else might have is welcome.
Thanks,
Matt | | |
