Kevin - So far everything checks out. The pad looks great, including the cowl. See if you can get me a straight on shot of your POP and I'll brake it down for you as well. A pic of the partial vin on the tran would be nice also.
The only thing that I have decoded differant is under the Option 2 L=M20/M21 4spd. This car currently doesnt have fold down back seat.

Is there any way other than pulling the cover on the trans. to determine if this is a M20 or M21? Everything I see has not indicated that this is not a M21.

Follow the RPO on the left hand column until you see M21 and check the requirements (off to the right). There is no way a M21 would have come from the factory in a L48. If it did it would show up here; http://www.camaros.org/pdf/options.pdf

Do you have any numbers off the side of the trans? This should tell us exactly what you have. You can find the "Maincase Casting Numbers" here; http://www.camaros.org/trans.shtml#4speed

Marty,
I have sent you the trans, and POP. I had a hell of a time locating the partial Vin # on the trans. It was located on top back by the tail housing. Thanks again!!

Yes - If the rpm drop from 1-2, 2-3, and 3-4 shifts is pretty much the same, it's an M21; if the rpm drop at 3-4 is significantly more than from 1-2 or 2-3, it's an M20.

Here are three of your four other pics. I'll work on the POP in the next day or so. Right now I have a date with my son, easy chair, and the Yankees and Angels. We're headed up to Cal next month to see them live so this is kind of a precursor. Wink

Could it be a M20 case with M21 guts or aftermarket gear set? Not up on Muncies as far as what will interchange, I know you cant mix and watch but could you change all the innards?

Kevin- Here's your POP (could not find RPO U15- Speed Warning Device). I don't think I have ever seen a closer car and engine build date; Car-10D, Engine-10/25.

Your "Guards, door-edge" is RPO B93
 
BTW, If you get some time and figure out this posting pics thing, would you mind posting your L48 on this thread? http://www.camaros.org/forum/index.php?topic=8314.0. This link might help you with posting pics; http://www.camaros.org/forum/index.php?topic=7215.0. Or, this one; http://www.camaros.org/forum/index.php?topic=4896.0

I always thought 4P was the code for SS350 not just a radius rod. L30/M20 also got the 4P but we know in this case it's not an L30 car so the 4P code would indicate SS350.

something doesn't add up - correct me if I'm wrong
a 350/ 295 would have a 4BBL carb - but POP indicates a 2BBL

Marty just made a typo.  It should be a R instead of a B for the carburetor code as Kevin has noted in reply #5 above.  R would make it a Quadra-Jet.
