you can get a general idea from compression numbers, but unfortunately everyone does it differently and uses different gauges.

best bet would be to ask the fellow who u got that 383 from.

The problem is the cam, the bigger the cam(the more valve overlap) the lower the comp.#, so you really can't tell without more info.
