The Ford Barn - View Single Post - Question on Cam Gear Marks

It can also be where/how the t-slot was put into the cam core. I've seen many mistakes on a variety of aftermarket cams, so nothing would really surprise me at this point. Another option would be to put an "advance plate" on the distributor (like we do on Harman Collins mags), so you have a lot more adjustment in the timing. If it truly has 25 degrees at idle and 35 total, then it explains that hard to start as the starter is trying to overcome the heavy advance at crank speed. Your TOTAL advance should be around 23 - 24 degrees.
