You are correct 70-71 SB 340 V8 was hemi orange. 72-73 was blue. The pic is labeled "not so stock" and I am not so sure there was confirmation of match to vin. The motor looks to have been apart to alter the manifold and add dress up kit. Hard to tell, but you start to think top end apart, cam upgrade? I hope the owner just opens a build thread to let us know.
Other things about color mentioned above. That car looks optioned with manual brakes (hard to tell), 4spd, and I don't see AC. Ralleye dash package and a super odd color. Maybe someone walked into Dodge dealer late in model year and ordered it. It got a blue motor because they were making blue motors that day for 72 vehicles. It could be a replacement motor as well.
The more I read and the more motors I tear down the funnier things get to me sometimes about the exactness on some of this. I have torn down stock virgin motors with stamps on pad that indicated a turned crank and oversize Pistons from the factory. It's all cool stuff and it surely is a cool car!
