Chris, congrats on an absolutely incredible score! This is such and enjoyable thread - just read throught the whole thing and I’m looking forward to following along as this car yields its secrets. I am especially jealous of the nice flat-sitting hood. My 74 Formy has the dreaded “bow” and it is one of the braced hoods. Keith’s engineering explanation debunking the myth that leaving them latched caused the bow was interesting, but I am curious as I am sure others are as to what, then, caused it and how do we correct it? Glad you don’t have to worry about it.

I’ll never forget the first time I saw a 71 Formula. It was Lucerne Blue with blue custom interior and it belonged to a guy named Billy Hawk in Chattanooga. I was driving my 71 LeMans to summer school at Baylor School and Billy was also going that summer. I thought that was the coolest front end and hood scoops. It was that car that inspired me to buy the 74 Formula when I was in College a few years later.

Some engine/underhood pictures as requested. The second and third pictures show that the fenders and inner fender liners are the original early style.

The first picture shows the top of the engine with the air cleaner off. There are some items that are missing, but the second picture shows some of the stuff that was in the trunk, such as the choke (I094), rear alternator bracket, the hot air stove (driver side), and one of the plastic elbows that attach to the air cleaner snorkels (the other one is missing).

The ignition coil is not correct, but those are easy to find. The second picture shows the fuel line on the passenger side frame rail. Someone has spliced the line using a rubber hose, which is about a half inch from the exhaust manifold. This is why I have not been driving the car, if that hose fails it will spray gas onto the hot exhaust manifold, so obviously I need to replace that fuel line ASAP. The third picture shows the distributor number 1112073, (date code 0H18).

The last pictures are of the AM/FM Stereo radio that was in the trunk. It's in real nice condition, and I'm pretty sure it's the original radio.

What's that cable on passenger side of choke pull Off? Macgyver thing?

Mike, It looks like a manual choke.

Yep, the original-looking part tag on it codes out as a '71 Firebird AM/FM Stereo unit. Nice!
Interesting, looking at the serial number on yours (1001112), it's only 15 units away from the '71 AM/FM Mono unit that came (in a box in the trunk) with the '70 T/A I recently re-purchased. What are the chances...?

BJ - I've wondered the same. It's been my observation that these things warped (if they were going to...) pretty quickly. I saw it commonly even back in the '70s.

My guess would be it had something to do with disparate temperatures of inner / outer panels when they were bonded together, or a different rate of shrinkage between the resin in the inner and outer panels after they were joined. It wouldn't take much....

Just a guess, though - my experience engineering hood systems is all around the metal variety.

Did it have the clamp for it?
