That's definitely caused by oil, and the oil is causing detonation, these 383's like to consume oil if you don't have all the details correct, aka piston to wall clearance just to name one, having said that I'd bet a lot of cash that your guides are worn so bad the seals can't do there job, some is pcv oil but that's a ton of oil lol, for a cam I'd go 227-235. 600 lift114lsa for good street manners and good power, that motor should easily make 450-475 rwhp setup with the right heads and cam imo
