Dissy advance curve

[rick r]

Have an 8BA with Merc crank, Isky Max 1 cam, 450 cfm 4 barrel. Have been running Chryco electronic dissy for years. Dissy is as it came out of a 318 at the wreckers. Seems to work O K , but always looking for improvement. My question, What advance should I be getting at 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm. All readings with the vacuum advance disconnected. Thanks in advance, Rick
