Thanks. Would you share your source as I don't have that info for EC although ED works just fine!

Thanks for your reply as I didn't know either worked.

Still need 870 block dated I-L 64. My vehicle has a CE with correct dates.

The EC came with a manual tranny, 4 barrel, and was special high performance.

The ED was basically the same except it had a transistor ignition.
