Good to know this group exists. I have a question to pose to you all. I own a '78 Trans Am. I recently laid to rest my original 180 horsepower engine. (The compression was way too low). Rather than opt for a rebuild, I purchased another 400 from a garage a few doors down from where I normally take my 'bird. Anyway, I've learned recently that the motor I did purchase was one from either a '68 Tempest or GTO. My heads have the number 62 stamped on the mid ports. However, question though, where can I find the two letter I.D. number for the motor? For whatever reason, I can't seem to locate it. This I.D should give me an indication of the horsepower,...I think. If anyone has any info that could possibly help me out or clear up this matter, I'd appreciate it!
