Hi guys,
81 Malibu 355sbc 11.89 @112
At the track, car started running rough, would backfire/ shoot gas out of carb when stalling.
Now the car is barley startable, will only start if I advance the timing all the way, runs like garbage, stalls, etc..
This misfire has evolved into almost not starting.
Iv tried:
-my new 750hp dp
-rebuilt 650hp dp
-2 hei stock distributors
-replaced intake manifold gaskets
-adjusted all my valve lash
Car keeps doing the same thing.
When we used to be able to keep it running the vacuum was around 10
Have you guys ever felt with this?
Did I get bad fuel? Slowly diluting my good fuel between warm up and then stalled after 1st burnout? Head gasket issue? Cheap jegs harmonic balacer, dont think its that cus can barley make it run at low rpm any. Its mark and hasnt slipped.
Starting to loose my mind!
Thank you
