We are finally getting around to getting the 73 Formula on the road. We have been working on the engine as we have time and it is almost there. If you remember this is the original paint 4 speed car I bought with no shortblock. I happened to have a 455 from another Firebird in the shop that we decided to use. Our goal is to make it look as close to a stock 73 400 as possible.

The block is a 72 yc 455. The heads are 1977 6X with 1.65 roller rockers. The intake and carb are the ones that came with the car as well as the air cleaner. I had the Ram air manifolds on a shelf upstairs. We kept the complete 73 smog system intact. We are using stock painted valve covers that will apparently need spacers. The chrome set are just for mockup.

All of the bolts on the engine came off of the 62k mile 73 350 car that we are cutting up. That engine had every nut, bolt and clip we needed. As well as just being great reference for wire and hose routing and colors, etc.

The engine is the slate blue. It is darker and uglier than it looks in the pics.

The fender was off to replace the heater core so we decided to just leave it off until the engine is done.

I think tomorrow we will have the engine in the bay. I will post more pics.
