Ford 460 Timing
 
I have a 460\535 crate engine and while cruising at 3000 rpm the engine seems to surge forward. I checked the timing and at 3500rpm the total advance is 35 deg.
At idle 950rpm the advance is 26deg. Is this a lot of initial advance and does the ford distributor that comes with the engine only give 10 deg of mechanical advance. I thought that maybe the idle was fast and some mechanical advance was being measured but it will not idle any slower. I would apreciate any coments or help. I am running a holley 750 DP.

Charly,

I believe your initial is way high. You can call the Ford tech line at (586) 468-1356. I think they will tell you your initial should be around 14 and the total at 32 to 34. Just keep in mind that every engine is different as you will have to experiment a little. Your stock distributor should put in about 20 degrees of advance at 2500 to 2800 rpm.

Surging and idling problems can also be indicative of carb mixture problem. I'm at 16 initial plus 20 mechanical using an MSD distrubutor. Idles in gear at 600 with a mild lope. (460 with a mild cam)
