    Unbelievable! I put in the AC Delco ICM with the MX-4 compound, dielectric silicone on the connectors and it runs GREAT!!! I thought I was getting a high quality distributor but, after 3,000...

    I got this spring from ebay, and running @ 28PSI with the adjuster barely turned in. I think it's from a 95-96 7.4L, so this may not help unless you go higher than you mentioned....

    I have been having the same issue with the timing jumping at ~2000 - 2400RPM (around 60 - 65MPH w/4,10 gears) in my 88 5.7. You can see it at 0:12:53:852 on this log.

    I was wondering if the ICM...

    In comparison to everything else, a cheap laptop is your best way to go. Then you can run TPRT so most on this forum can help.

    Sounds like your O2 sensor isn't staying hot enough while idling. Try a heated one?

    Just a thought, have you tried DFCO (Decel Fuel Cut-Off)? My 88 (7747) came with it, good for engine braking too.

    I bought an 84 Dodge (new in 84) W150 with a 360 4BBL, it burned about a qt/1000 miles for about a year. 1 day it wouldn't start (turns out the distributor reluctor was bad), after cranking forever...

    Bummer - hope it's something simple like the rings' gaps lined up in a row vertically (I've seen it before).

    You can try playing with PE-AFR. Sorry I can't help with your WBO2 in the 7747 which would help tremendously for this stuff.

    I have an 88 350 with similar mods, maybe a little more aggressive. Try throwing more spark at it until you get high KCs, then throw in more fuel. This is what I had before I went to the EBL...

    Thanks, I was thinking of permanently installing a gauge or Schrader valve just behind the TB so I don't have to crawl under the truck each time, I don't do bend-overs much anymore, lol.

    I ordered the spring but still need a pressure gauge, does anyone have a setup (tee and gauge with fittings) they have used? Then, once I install the spring I guess I'll have to relearn my VE tables...

    Thanks Brian, according to the EBL Utility calculator their flow will go from 71.8 - 92.7#/Hr so, I'm figuring my 114% DC will go down to ~88% (if it's a linear calculation) which looks to put me in...
