Anybody have any idea if these numbers can tell me anything about this converter? It measures 10 inches across, is about all I know.

If you know who made it..They can look up the specs based on your number.

Hi That would be a Dynamic 10" street converter built back in 1990. Behind a mild small block you should see approx.3200-3500 stall, behind a mild big block you should see approx 3600-4000 stall, of course this will very depending on your particular combo and variables. Hope this helps you out a little.

That helped a bunch!!! Thank You Lenny!!!
