  1. Thanks. As soon as I can pull it back on the lift I will post some pics.
  2. The front of my 71 Mach was pretty noisy, so I rebuilt everything on the front suspension...EXCEPT the springs. They looked to be in good shape, so I just replaced the insulators and the perches with a pair from Scott Drake. It's better. no rattle, but still gives me the "boing!". Will bad springs be noisy like that? Or will they just sag. I know that the simple answer is "just change the springs stupid" but I also notice that the passenger spring seems to be rubbing against the outside of the tower it sits in. I thought that it was being caused by a worn out control arm, but now I'm not sure. Does that mean something is seriously wrong with the subframe? Thanks!
  3. Hi everyone. I’ve rebuilt the front suspension on the ‘71 but the adjuster sleeves are so seized I can’t set initial toe in/out. The clamps are loose. I Soaked the sleeves in penetrant for 3 days and even tried map gas. They will not budge! Any suggestions?
  4. Back in the states. Took her out today. The learn function is a good start but there’s a lot of fine tuning options too.
  5. Installed the new replacement Sniper today. She runs great! I want to thank everyone for the help. The advice will help me to really get dialed in! Merry Christmas.
  6. Welcome from Tennessee. Beautiful car.
  7. Update. The Mach has been at a tuning shop for 3 a month now. They have also ruled out anything mechanical and they didn’t have any better luck than I did, So We called Holley. They are going to swap out the unit with another new one.
  8. I took a look thru my sockets and the cheapie with the u-joint on it is more than 1/16” thicker than the others. And, like Chuck, I have one that I tapered down on the bench grinder as well.
  9. I have 3 different brand spark plug sockets In my box and they are all different wall thicknesses. I remember running into an issue like that on a 289 years ago.
  10. So I was able to get thru to Holley tech. The guy was great and spent Some time with me looking at my datalogs. Didn’t find any issues though. It does not matter how rich or lean I run the engine, the condition doesn’t change at all. my Leak down test was good on all cylinders, less than 4% loss. Compression is 180-190 on all cylinders. I give up. It’s going to go to a tuning shop.
  11. Leaning out the a/f didn’t help either. Next step..I’m going to do a cylinder leak down test and see if something may have gone wrong on that first day out?
  12. Update* accel. enriching didn’t change anything much. I Took it from the original setting of 49 and trying 2 lbs. at a time, went as high as 63 and as low as 26. So I took it back to 49 and left it there. I did notice though, that I’m getting a very rich smell when test driving. I’m going to try changing the a/f settings and see if that makes a difference.
  13. Enriching the mix makes sense. I've eliminated fuel pressure issues. 60+ at idle and acceleration. Do you think I'm using the correct timing numbers? (15* idle, 36* cruise, 34* WOT)
  14. Everything has checked out good twice. I was able to talk to Holley Tech today. They asked me to Install a fuel pressure gauge In the feed line at the back of the sniper to make sure I’ve still got 60 lb. going to the Sniper and I’m waiting to hear what they find out with the Datalogs. I’ll post more later.
  15. Thanks Don. Voltage & grounds are good at all connections. I even went back and replaced a couple of connections just to be sure. I did flush the new lines and new fuel tank At install but removed and checked today just to be sure. I just did a removal and visual check of the O2 looking for any debris etc.. I hadn’t thought about the harmonic balancer. I’ll check that out and I’ve just been going by the hyperspark and sniper for timing numbers. I’ll put a light on it also.
  16. Also, I set up the wiring the way Don instructed and should not be getting any RFI since everything in the system is matching Holley components and made to work together, but I guess if any of that was a problem, it wouldn’t have run so good the first 200 miles?
  17. EVERYTHING WENT BAD AFTER THE FIRST DRIVE! So I got everything done on the Sniper install and did the initial programming. The first day out was great. Put about 200 miles on, stopped at a couple of cruise ins and it ran great...BUT THEN...went home and later that night tried to drive again..PROBLEMS! It’s a little harder to start now but the bigger issue is a stumble and miss on acceleration. I can hear a ‘rattle’ in the engine when I accelerate that I think is a spark knock? I’ve tried everything. Triple checked for vacuum leaks. Replaced the vacuum lines and the trans modulator Valve just to be sure. Then I routed all of the lines to the tree on the back of the intake, just to get vacuum away from the Sniper to rule that out. The distributor & ignition Is a new Hyperspark set up that Holley recommends for the Sniper. The plugs and wires were new and looked great but I owned the wires and changed the plugs anyway. MSD wires Autolite gapped to 42. I did the old “spray carb cleaner around the intake manifold to check for vacuum leaks” trick I’ve gone thru the troubleshooting chart and everything checks out ok. I reprogramed the Sniper several times. The O2 Sensor looks good. Everything is “within the reasonable AFR targets” IAC is at 6-7. The problem is quite not as bad with my timing set at 15* idle, 36* cruise, 34* WOT. I called the Holley tech line twice but sat on hold both times for over an hour but never got thru to anyone. Everything from the air filter to the fuel tank is brand new. If it hadn’t run so good the first time out, I wouldn’t be so confused. Does anyone see what I’m missing here? Thanks!
  18. Howdy from Nashville TN!
  19. I got the friction modifier from Ford and went 7 places before I found the copper washers. A felpro gasket with a thin coating of 81182 on both sides seamed to work good. I Just got back from a long test run. Problem solved! Thanks everyone.
  20. Can you post a pic of the coil? The way it’s cracked may tell us something.
  21. I’m putting her back together tonight! Since I don’t want to do this job again. The plan is to put on the new copper washers with a new gasket and a light film of black or gray RTV on each side of the gasket. Does this sound like a good plan? Or is it better just to put the gasket on dry?
