Been battling this timing retarding issue for about a week now. Thought it was the cheapo hei yea yea I know it doesn't belong but it was cheap when I needed something. Long story shot I would bring it to 3k and the timing would advance to 35-38 then start to retard and when I let off the throttle the timing would drop down past zero and slowly come back up to 12 which was my initial.
I pulled the hei today to check the gear and while it was fine I shoved a flat head in there and pushed the cam and it moved so I pushed it the opposite way and it walked damn near 1/4".
I just put this motor in from a explorer and had the cam out to swap in the mustang cam I know I bolted the thrust plate back up but I guess I didn't notice any damage to it. Does this sound legit? I read the plates are a common issue but common enough to walk that much? Obviously I will have it apart this week sometime and see what's really going on but just putting it out there for some advice before I get into it. Is there a better thrust plate to buy or is there a button like chevys that I missed? I know I didn't see a button when I tore it down.
I used the mustang cam and timing set but used the explorer plate.
