bellhousing question
 

will the bellhousing behind my '69 c20 350 fit an ls engine?

tia,
buddy

The answer is yes. You will not be able to use all the bolts the LS engine has but it will bolt up and function.
Flywheel or flex plate issues are harder to deal with. But it can be done.

Thanks. Can you elaborate a little about the flywheel please?

Few engines through automotive history have the same consistency and interchangeability that the Chevrolet Small Block & GM Gen III+ engines have. GM power enthusiasts like us were relieved to find that the GM Gen III engine released in 1997 had essentially the same block bolt pattern at the rear face as the previous Chevy Small Blocks, and the same crank bores for the automatic torque converter pilot journal and the manual pilot bushing area.

However, the crank flange spacing, bolt pattern, pilot bushing bore changes and flexplate / flywheel configurations play importantly into interchange.

This will help. I didn't know which LS motor or if you have and automatic or manual.
This guide helps a lot.
Check out the LS Swap area of this forum for more information.
It's under the Engine & Drivetrain section.
Here is the link.
