Will a 350 Chevy motor and transmission fit into a 78 Buick lesabre?
no not usually a Buick and Chevy bolt up patterns are different now im not sayin you cant you can but will take alot of fabricating so i would just leave it at no you cant
Yes!!! A lot of the Buick, Oldsmobile, and Pontiac (BOP) used transmissions from the mid 1970s thru the mid to late 1980s that were called "Dual Bolt Pattern Transmissions" and these transmissions will bolt right up to your Chevy V8,as well as the BOP V8 ENGINES. If you are unlucky enough not to have one of these transmissions an adapter is available from a number of sources and they are not very expensive. Try SUMMIT OR JEGS for purchase information.
Other than the bolt up issue be prepared to change engine mounts,Engine Flex-plate (A lot of people call it a FLYWHEEL)(that bolts the crankshaft to the Transmission Torque Converter),make exhaust system modifications as well as changes to electrical wiring, changes for fuel line routing because of different locations of the fuel pump and starter.
Although this is a great swap it is NOT A BOLT IN DEAL. I recommend that you contact either the SUMMIT or JEGS Tech Help department for more information and have all needed parts on hand before starting this project....GOOD LUCK, ......mopar392
1989 pontica Bonneville and you bauht a 1990 Buick lesabre motor look the same but will it interchange with no problems?
yes and no yes in that it can be made to fit no in that a Chevy transmission has a different bolt pattern than Oldsmobile's, Buick's, and Pontiac's. the motor mounts are also probably going to be different. However you can change the motor mounts and there are companies that make adapters to use a Chevy transmission with a Oldsmobile, Buick, or Pontiac engine. I have seen an adapter to use a ford transmission with…

Seriously? A 305 Chevy motor does not take "transmission fluid"! The transmission takes transmission fluid, and the motor takes oil. The 305 should hold 5 quarts of oil I believe. As for the transmission, I believe that all depends on what transmission you have. Seriously? A 305 Chevy motor does not take "transmission fluid"!
