Finally Fixed High RPM miss on the S-10

Hey guys,

I finally got the high RPM miss problem taken care of in the turbo engine. It is something that I can honestly say I feel like a retard for not doing better to start with.

I was running the Edelbrock Ignition Amp that came with the ProFlo. As it turns out that thing is nothing more than an HEI module in an edelbrock cover. I knew this, but figured with a hot coil and good dwell control it should handle spark fine. I was wrong.....

I finally took the MSD off of my 57 and installed it in the S-10. Wow, what a differnce. There is no hint of a miss now and it will pull up over 6200 without so much as a flinch. Runs smooth as silk when it revs up. Also runs like hell....looks like I will have to make a trip to the track in the near future.

Chris

As an electrician by trade but really applies to any troubleshooting, I've found is that we all tend to think that the simple problem can't be it. I'm as guilty as anyone. We have a problem and we look for some deep, complex issue when it's right in front of our nose. Good catch!

Not to hijack the thread but to illustrate how true this is, here goes:

A dealership brought in a recently rebuilt engine to diagnose/repair a knock.
I spent quite a bit of time measuring carefully the clearances, looking at the bearings for abnormal wear, etc. After abour 45 minutes of me playing Sherlock Holmes, my partner looks over my shoulder for about two seconds and pointed out that there was a lower main bearing half in the block (no oiling hole, you know the rest)!

MSD is awesome for so many reasons!!! Can't go wrong with any MSD set up. Glad to hear your problems are fixed.

I promise a video with sound when I get it to the track. It has a little different sound now than in the past. It has alot more of the turbo chirp and howl than it used to. Sounds pretty good.

the MSD 6al I had wouldnt work for me, It kept over heating on me with in about 10 min of driving. I tryed to get a hold of tech on their website since it said to do that before calling and there were posts 6 months old that had not been answered. I dont know if I had a defective box or if it wasnt compatible with my coil or what, but with in 10 min it would just shut down and then start up again about 5-10 min later. Maybe the 6 series is just cheaper components that the rest. I want to get a digital 7 for my engine later on but I want to look into them further to see if that was common and if i need to run their distributor and coil etc.
