Can some give me a clue as to what the letters/numbers after the 320/360 mean for Lycoming engines ?

There are some old threads leading to a site that is no longer in use which apparently explained the nomenclature. Is there a new site ? I have a handle on the prefixes like I= injected, O= opposed, T=turbo.

Thanks,

Darren

Here's the index:

Then if you click Current Models, By Make, and L for Lycoming, the TCDS list index is displayed e.g.
