I have spent much time trying to get my 360 to run crisper below 2k. It is what I would call a flutter.
Engine is a 5.9 with EQ IMM heads (9.7:1)
222/229 @ .050. And .509 lift on 112 cam
Airgap with an AVS2 650
Dougs headers
Timing at 19* mech adv of 14* starting around 1000 and all in by 3000.
17* of Vac adv starting @ 12” and all in by 18”
Idles at 800 rpm with 14” in nuetral/12.5 in drive.
AFR is around 13.5 at idle and 14.5 at light cruise.
Cranking compression is 168-175 psi
I have tried both HEI and mopar electronic.
Orange and chrome boxes. 3 different distributors and installed new plug wires/ gapped the plugs to .034
Maybe I am just imagining this and its just the way it will run ?
Any thoughts?
