Never had this issue before…
Just rebuild my 440 .030 over very mild cam performer intake w/ Holley 750
Dizzy is Summit Electronic Billet w/ ICU
Seems to like 10* initial which puts the total at 42*. The total timing is 34* with the VAC Adv off. I have adj the dizzy advancement plate back but still have to much total. Is this to much total? I don’t why I have such a big swing from initial to total. If I go 13*+ initial it wants to diesel over when I turn it off after it is at temp. I’m missing something. Probably going to swap out for HEI tomorrow just to see.
