engine still runs lean
this seems to be an ongoing project for almost 2 seasons.
i have a 350 sbc with AFR 195cc heads 65cc chambers, i re-camed the engine about 2 weeks ago with a new Comp Cams solid flat tappet 510in/522ex 226in/232ex, im using a Edelbrock RPM air gap intake with a 650 holley DP. its a 9:1 compression motor and i have 35* advance at 3000 RPM (hei setup).
drivetrain: th350 w/ 3000 stall, 4.10 gears
this has been a very frusterating project, for the life of me i cannot get this engine to run richer. if i free rev the engine and idle it i could pull out perfect looking plugs a good golden brown color, but the second i drive the car and put it under and load or just cruise around i pull out grey white plugs, indicating that it needs more fuel. the funny thing is that i have went from a 72main /80 secondary on my 650 all the way up to a 80 main/ 90 sec. it dosent seem to have any affect on the way the plugs look. the fuel pressure is fine all the way up runs around 6psi. i would think by now i should be pulling out black plugs but i dont seem to be anywhere close.
there are no vac leaks either...
what could i possibly be missing, ive never had this much troubble tuning a small block this simple
