I haven't read this whole thread but I think a partially plugged radiator and or faulty thermostat, fan clutch might be the culprit to the higher temps.
Would pulling timing out of it at WOT likely cause it to go rich rather than lean?
Try this little test. While driving when it does this lift up slightly on the shift lever. Not enough to change gears but just a little bit toward neutral.
Yup. That's the one I remember. You put up a couple vids running it around the neighborhood, keepin the neighbors awake.o_O You have had some cool toys my friend.
Oh my. It has been a long time then. I'm curious to see what it looks like now too. You had, at one time, about a 58 Chevy truck with 6.2 turbo or something like that. Dually? Long gone I guess?
Hey Richard.
I ran across this pic recently and thought this one might have belonged to you for some reason. Don't know how long I've had the pic. Not sure what forum it was posted on. Is this one you owned some time in the past?
Just curious on the particulars and what became of it. 1/2 ton...
