Unhappy stupid emissions

I am looking to see what emissions came out on a 77 chev. I think I am going to change the cabs with my 85 to get away from all the ones in 85. Does anyone have any ideas? rolleyes:

I dont know exactly what you had on yur truck, but there is a sticker under the hood by the radiator support, just to the left (or passenger side) of the hood latch. Its a vacuum diagram, it also shows emissions components. It should say if you have a cat or not, it will also show if you had the A.I.R. Pump, EGR, etc. Check out that sticker to help you figure out some of the components. Others Im sure could help more.

Welcome to the board also.

Ohh no! Maybe one of the guys with a 77 could help you out. You may try changing (editing) the Title of this post to "Help with my 77 Emissisions System".
