My first car was a 1972 Chevy Nova. I still have it and drive it now and then!
This had been my moms car for years but had developed some mechanical problems. When I was old enough to drive, mom and dad offered to either get me a "working used car" (envision 80's Nissan Sentra or other equally valueless piece of scrap metal

OR pay for repairs to the Nova so it was usable again. I chose to get the Nova running, thankfully. Learned a lot about car repairs which helped me greatly to get where I am now; from a technical standpoint.
Fast forward to the late 90's / early 2000's. The original 307 V8 engine was very tired by 200,000 miles. I bought a complete junkyard 305 engine, with throttle-body injection setup. Came from a base 1991 Camaro. I stripped everything from the Camaro, insofar as the engine wiring, ECM, and all the sensors etc.
This was the early days of EFI engine swaps and it was very hard to find information on doing such a thing. Had to fight my way through GM's "PassKey" anti-theft system and ended up building a circuit to defeat that, before anything was available to buy for that purpose.
Before installing it; I took the 305 apart and freshened it up with new gaskets and bearings etc. The 305 is still in the car and has had zero issues. More than doubled the fuel milage, and has more power than the old 307.
Sincerely,
David

the engine bay as it sits now; with the now decades-old engine swap still in place.
