4.0L HO Jeep Engine Build

I understand. 8 degrees more ign. timing plus more cam timing does equal quite a bit more cyl. pressure and since the dist. is not adjustable it may create a phasing problem. do you think there is any way you could modify the crank position sensor to be adjusted? I've seen guys do it on other engines. If you could make it adjustable, or even just figure out how to retard it a few degrees that should be good enough.

BTW: back in the day when you were tinkering with Ford's did you ever try advancing the cam timing on any to see what it did? I remember working at a trailer shop that had a 1 ton Ford with a 351 modified that was shot and the boss asked me how we could make it have more power. I said since we had to change the engine anyway we should put in a 400 modified. Man was that thing a pig. I tried everything I knew at the time, timing re-curve, carb jetting, (but I didn't know they retarded the cams) and nothing made it run any better than the old worn out 351. If I had known about the cam timing I would have tried advancing it. It was also terrible on fuel. Best it ever got was about 6-7 mpg. The old worn out 351 got about 10 mpg.
