Engine size for 1990 Chevy Caprice classic?
It's most likely a 305 V8
To put a front sump oil pan on a newer Chevy 350 engine out of a 1990 Chevy Caprice any suggestions?
Why wouldn't your headlights on a 1990 Chevy Caprice Classic come on when you've checked the fuses and they are ok?
I will assume that the car is fuel injected/computer controlled carburetor. You will have to replace the intake, the carburetor and the distributor. These parts can be found at your local junk yard. Care should be taken when selecting these parts, that they are taken from a non-computer controlled chevy. If not available, these parts can be purchased from a performance parts dealer, i.e. eldelbrock, MSD.
A 350 Oldsmobile engine has a different bolt pattern than the Chevrolet engine. The 350 Olds and 350 Pontiac engines have the same bolt pattern. The 350 Chevrolet and the 350 Buick engines have the same bolt pattern. Unless you have a dual bolt pattern transmission (there are some out there) in that Chevy, the Olds engine won't bolt into the Chevy transmission.
