Just rebuilt my 69 351 Windsor - it is all stock and mated to an FMX tranny. Completed the break in but I am having trouble getting the timing set.
With my initial at 6d, vacuum line disconnected and plugged, I have full advance at 31d at 2,800 rpm.
With initial at 6d and vacuum line connected I get + 45d advance at 2,800.
Idle is ok but terrible as rpm increases.
I have tried initial at 11d with the vacuum line plugged and get 36d full advance. Idle is good but sluggish throughout.
I am planning on trying to connect to manifold but would like to hear from someone else about this before I try it. I haven't looked inside the distributor yet to see what the limiter is set to.
Thank you guys in advance for any insight provided...
Oh, I also apologize...I do not own a Mustang...I have a Fairlane 500 convertible. I hope that doesn't affect the responses.
