I put my thermocouple right above the exhaust flange on the turbo. The highest temps I've seen are around 1050F, -but I'm running mediocre fuel with 18-20 PSI on a 19:1 engine, -so EGT's stay pretty reasonable. I'm not getting near the amount of fuel that a lot of the DS4 folks are (I'm...

I figured I already knew every swear-word in the english language working on my 6.5(s). I'm hoping to not do any actual wrenching on the 7.3, -I have enough of my own stuff to wrench on. I am smack-dab in the middle of a bathroom remodel to boot. Maybe I should tell him to use a shop-rag on...

Does anyone have a tool for removing the carbon in the injector holes of a 1990 7.3? A friend I work with has this truck, and he is looking for an easy way to remove the carbon buildup down in the injector holes. Supposedly there is a special tool made for doing this, and I was wondering if...

Everything you said makes sense, -and I would understand about heat being a potential problem under sustained high-fuel operating conditions, -absolutely. But, it would be cool to have a means of controlling that mechanical timing retard with a dash-mounted cable or something. Then, if you...

Hey, those pictures sort of clear things up a little, -good stuff, thank you. It looks to me like the advance piston advances the cam ring by using transfer pump pressure. That makes sense, because the cold-advance solenoid opens and closes a valve that supplies the advance piston the fuel...

Nah, -what I meant was that I am the retard!!:hihi:

Just to add a little more, -I was in a hurry and running out the door when I was making the original post. The way I understand it that advance is desired as engine speed increases, because you obviously want to give the flame front more of a head-start (so to speak) to make the most practical...

Ok, here's a dumb question that's been in the back of my head now for quite some time. Why is it that on our IP's (particularly on the DB2), when we increase fuel rate, -we retard timing? I understand that mechanically pulling in a bunch of advance if you were lugging the engine along in...

Yes indeed, -and it can also "store" more energy as well. I remember switching out the 8" balancer on my 283 SBC and swapping it out for one of those small 7-1/4's (or whatever they are) -and noticed a HUGE difference in throttle response and gained a few more R's on the top end. Everyone...

Holy crap, $900 for a clutch is hella-expensive. I did know a guy that tried a 12" single-disk kevlar setup on his BBC truck, -he said it was too soft. I tried a DF centerforce on my 402/SM465 and it worked pretty good until I smoked it doing a hillclimb in 3rd gear. I'm curious how the zoom...

Nope, -it wasn't me with the Zoom, -must be somebody else. Unfortunately I am running the Luk. On a side note, my disc looks different than the one in the photo. Overall, I'm not very impressed with this clutch. I ran a full ceramic 12" on my 402 BBC truck with the 465 trans, -and that thing...

It sure does seem like it's timing related. With a smoke show like that (looks like one of my 18:1 cold starts) -and the fact that the EGT's are through the roof, -coupled with lots of turbine drive pressure (making lots of boost during low fuel rates), it sure makes one wonder if the timing...

Yes, and all that being said, "fatigue" (as described above pretty well) IS CUMULATIVE!! Taking a piece of metal (that is already marginal) and placing it into an application that is already taking the life out of it (more-so on a 6.5 than a 6.2), -and you surely have a recipe for trouble...

Yep, -something I take just a little pride in. I'm "beyond done" with PMD's and DS4's, -just not my cup of tea. Admittedly, the DB2 isn't perfect either, -but it always starts at the mere bump of the key, -and delivers fuel "right now". It makes for a really fun to drive combo with the 5-speed...

I'm keepin' my 6.5, -no question about it...........:agreed:

Let's see, year 2010....I have just been changing the oil every 2000 miles or so (because of my minor coolant in the crankcase feature). I have probably added at least 3-4 packages of the GM coolant tabs to keep the coolant situation under control (or at least at bay). :rolleyes5:The truck has...

Beautiful job on the harness, -mine is on its last leg and needs some attention pretty soon. If priced right, I'd be up for one of your setups, -everything looks top notch. I also love the bowtie on the engine stand! Ford engines don't belong on a stand, -they belong on the end of a chain...

Well, it's kind of a horror-story, but now you know...

You can imagine the hair standing up on the back of my neck after what happened. I swear, I was afraid to even touch the damn ignition switch on the steering column after what happened. After I put the 599 together, it literally took months before I relaxed and started actually "driving it" like...

I sorta feel like I hijacked this thread, -I apologize. The same 599 build is running, -with a quirky DB2, -and losing about a cup of coolant a week, -no biggie really. The thing still runs great, -always starts, -get's mediocre fuel economy with my GM4 wastegate tied shut, -is coming up on...
