318/360 Flywheel and 318 Poly

[392charger]

I'm trying to find out if a 318 and 360 flywheels are interchangeable? Also wondering what a running 318 Poly (wide block) is worth and does it match up to the small block or big block 727?

Thanks

IIRC, the poly is internally balanced like the LA teen and 340 but the 360 is externally balanced. The flywheel will fit but it's not balanced the same. The poly is a small block and I have no idea what they are worth....
