Hello everyone,

I guess I have finally been hit by a midlife crisis (I'll be 40 soon) I bought a daily-driver (generous) condition 1967 Firebird that has non matching #s body, engine and trans. What makes this even more interesting is that I am not what you would call "mechanically" capable. That is the very reason I didn't purchase a matching #s car, but one that I would like to fix up to the point where it will be a daily driver....and maybe learn a little with regards to cars on my little journey. So, I am seeking help in both the Firebird area, and possibly the "home mechanic" area. I will leave the big tickets items (engine rebuilds etc) to professional shops, however I wouldn't mind being able to do just about every small and mid level job on this vehicle myself. The vehicle itself has been "partially" restored, one of the floor pans was rusted out and it was replaced, not a good job...but it's "ok." There is some surface rust on the undercarriage. Vin indicates that this was originally a 6 cylinder coupe.

I plan on ensuring that the vehicle is mechanically sound first, which I believe will require a thorough look over the engine, trans, brakes and suspension...here the learning curve will be pretty steep but I will do what I can by myself and find a competent mechanic for the harder stuff.

This will be followed by redoing the entire interior, and getting the gauges hooked up and working. This part I will attempt to do mostly myself (tear out the seats and get them upholstered etc). Eventually (years from now) I will redo the entire body, but that is a long term goal.

So, without any further ado, I have my first questions.

I have been trying to figure out exactly what I have from an engine perspective. The gentlemen that sold me the car told me that it is a 1973 Pontiac 400 with a Holley 4160. It may, or may not have been rebuild at some point, I am not sure. So I have been looking for the Date Stamp and can't find it, however as you can see below in the picture I did find the XY, which indicates that it is a 400.

So could one of you fine folks do a noobie a favor and given the attached pictures tell me what I have :from an engine perspective? Also, if there are any more firebird resources that can help me with my project, please advise..thank you very much.
