Flywheel??

[Sinner]

hey everyone hopefully this is the right place to post this but I've been looking for a flywheel. I have a 68 273. I could get one new for almost 300 bucks but I've been shopping around on Craigslist. But quick question, is a 318 and a 273 flywheel interchangeable?? I've done some research and a lot of people say it is but I rather trust you guys.

Try 440 Source, that's where I found mine. Flexplates & Flywheels-440 Source

A 68 273 and 318 share the same 130 tooth flywheels.
Earlier 273s used a 122 tooth wheel.

Balance wise you're good. I believe only the 360 and 5.9 magnum have unique balance in the small block lineup, iirc

The 440 source flywheel comes with weight attached for the externally balanced engines. you just remove the weight (2 screws) and your good to go.
