I am 56 bought my mustang when I was 15. I saved my money from mowing lawns. I helped my neighbor rebuild the engine in his 68 Torino and fell in love with the car. I  saw a 69 Mach1 S code in my high school parking lot and bought it for $475.00. I drove it till the middle 80s and started restoring it. I think I am almost there it looks good runs low 12s possibly high 11s with a driver mod.

I will see you there once again.

I feel your pain Jay. I broke 2 yrs in a row on the starting line  at the FE Reunion. Hopefully I"m done with that.

I got it fixed it tonight finally
  I went to change the coil out with the new one and found the positive wire pinched under the valve cover. I was pretty sure that was the problem so I repaired the wire and test drove it. It had the same symptom ran good till I got a few blocks and was missing and surging, I went home and replaced the coil with the same result. I replaced the cap and rotor no difference. I replaced the coil wire same thing. My neighbor came over and offered me his msd tester which was in his race car trailer across town. Long story it sat at 9000rpm on the tester didn't miss a beat. The last thing to change was the plugs. Guess what problem solved. I never had plugs behave like that before. One of them had the center electrode worn below the ceramic. He was all over my shit about that. We test drove it and it ran great. After he left I went to look at the plug and they all looked good. Upon closer inspection one had the electrode loose that would slide from .040 to .200 or .300. Well it got a good tune up at least.

I took the carb apart tonight and its spotless. I will order a new blaster coil, cap and rotor and hope for the best. I found the carbon button in the dist it was not bothering anything. If its not the coil its the 7al or the dist. It did run fine for the first 3 mins and then started its blubbering. While I was warming it up i could hear an almost  popping like a fouled plug kinda sound. but I know its not a fouled plug. we will see hopefully it shows up Friday.

I belive its 26 spline. I bought mine from Brent he beat Summits prices. Was it a bronze pilot bearing? I bet the hole was way to big. The new clutch material kills the bronze-brass bearings. I put in a roller bearing.

I do my burnouts in 2nd but you wet the tires first. I also have the TKO600. This time out I got the tires good and hot and tore the perches off the rear and broke alot of expensive stuff. Check your welds on the perches.
