Chevy Engine Swap, Blazer 350 into my El Camino

I need to know if the 1977 chevy blazer engine with a 350 4 barrel carb california car, will fit in my 1978 chevy el camino california car originally equipped with a 350 4 barrell. My issue is the emmisions vaccum line routing diagram, i cant find them online for either car, and im worried the components are different, so if i was to install it and go get it smogged it would fail, because of different components or possible locations of them. in example.... vaccum air pump, egr valve, diverter valves, thermostatic air cleaner a kind find a diagram for either motor online to compare the two california cars not federal..... Any help you can give me would be great, I know in california your not supposed to swap motors with a motor that is older then your car year, but with one year difference with the same engines im hoping they will both be identical. Can you please help me, thank you

Rewiring entire 1971 el camino interior and under the hood


Wow, quite an undertaking. I had an '81 El Camino and wish I had never sold it. Originally it had a 267 c.i. V-8 with a Rochester 2bbl carb. I put in a Chevy 350 4-bolt main crate engine, Edelbrock intake and carb, and Hedmann headers (it ran like a scalded dog LOL). My advice is to look for a Haynes manual covering the '71 model year. They have complete wiring diagrams in their manuals, but the wire routing will be up to you. Good luck.

I have a 85 chevy elcamino. It has a 305 engine in it that needs to be replaced,along with the transmission. I have a friend that will give me a early to mid 90s chevy caprice with a 350. Do you think that...


Providing that the valve covers are the same, the engine should fit. It would be easiest if both transmissions were identical but you can use a 350, 400 or even a 700r4 in there with some mods and a crossmember move and possibly a driveshaft mod. You will probably want to swap intake manifolds and all brackets for stuff up front as well.
