Hi Everyone,
I finally found some extra time and money to fix both engines on my 1976 & 77 GMC's. My mechanic friend looked over each engine and noticed that someone had replaced the 455 with a chevy 454 engine on the 1976 model after he checked the casting numbers and had started rigging up some type of fuel injection system (will get more info later on that). Bummed out about that because I thought since the owner lived in Calif when I bought it, that it was legal but I guess not..!! We have a rebuilt 455 standing by to replace it with but he also stated there is no smog equipment, as if it had all been removed... Now I am faced with trying to figure out where to go and find whatever parts are missing. My question is: Does anyone have a list of these parts that are required to help it pass the silly California smog check...? My first thought was trying to locate a junkyard but I am afraid that all I will find are worn out parts....
Now as far as looking at the 1977 model, he concluded someone blew the engine and he can rebuild it while still in the vehicle but it also was missing all of the smog equipment. My concern here again is What Parts...? I have no idea what I am even searching for...? Obviously I will need a smog pump and that should be a new unit instead of any old one I happen to find at the junkyard... But I am very open to any ideas on how to solve these issues.
Sincerely,
- A.J.
