Sac79 Posted August 1, 2020 Author Share Posted August 1, 2020 I'm glad things are going well. And, your vacuum at idle is good. However, I've never heard pinging at idle. And I doubt that's what you heard. But it sounds as if the engine is starting to run well. Congrat's! Thanks Gary, yes I'm very happy with how the engine is running now. Now I just need to sort out the minor coolant leak and the leaking oil pan gasket... And hope for the brakes to sort out themselves. Looks like you are close with BB too, I'm looking forward to seeing(or reading about) you run it! Link to comment Share on other sites More sharing options...
Sac79 Posted August 1, 2020 Author Share Posted August 1, 2020 Hi Dave, I think there's some confusion between my post and Jim's reply. I haven't heard any pinging, not adjusting the carb anyway. The ticking sound I heard that I thought might be 'pinging' was when I adjusted the distributor and went too advanced I think. The vacuum increased, but I heard the ticking sound, so I backed it off. Anyway, it runs great now, so I'll see what the plugs look like in another 100 miles or so. I see you have AC now, I bet you're enjoying that. I'm super envious! Well it don't take much to confuse me The ticking when you went to far with the dist. could have been pinging I have never gone that far before to say I have ever heard it but if you backed it off and it stopped I would say you are good. I would check it with a light when you can just to make sure, would hate to hurt that new motor. Talking of new motor how many miles are on it? Some low RPM to full throttle pulls will help seat the rings just keep the RPM from going to high is all.\ A few heavy loads in the bed will help also. I would say till you get a 1000 miles or more the rings will not be seated. Yes have AC now and just in time as the front fan stopped working in my Durango. With AC and the over drive its a nice truck to drive. I took back roads to 7pm / from 12am work last night and in OD at 45 MPH the motor was turning about 1250 RPM, 55 MPH is about 1500 RPM. The 300 just likes to pull at that low RPM where a v8 I don't think would be happy. Time to load up the trash in the "garbage truck" as Jim calls it for its weekly dump run Dave ---- Dave, I've got about 140 miles on it now. I've already hauled a yard of dirt and 4 yards of mulch. So it's had some loads and I've been driving it enthusiastically in between. At least in 3rd, now I can give it a few pulls in 4th too. The engine builder also mentioned a 1000miles as the extreme for the rings to seat. So I'm not too concerned yet. OD and AC sounds great, enjoy it. I might consider a 5 speed swap one day. But for now I'll just take it easy on the back roads. Although I did go on the interstate and Eddy was not complaining at 70-75, but that no doubt contributed to the sub 9MPG...

Sac79 Posted August 1, 2020 Author Share Posted August 1, 2020 Honestly, adjusting for highest vacuum or idle speed is probably best. That's what my engine builder said. Apparently it's an 'old school' way of tuning... Link to comment Share on other sites More sharing options...
Sac79 Posted August 30, 2020 Author Share Posted August 30, 2020 Honestly, adjusting for highest vacuum or idle speed is probably best. That's what my engine builder said. Apparently it's an 'old school' way of tuning... Yesterday the wife and I went for a little scenic drive in Eddy, out to a covered bridge about 40miles from us. It was a really enjoyable drive. Eddy behaved exceptionally well. I was taking it real easy, 55Mph max (mostly 45-50) all along back roads. The drive was smooth and comfortable. We were able to only use the vent windows and rear window with overcast and mild weather. Yesterday was an exception though, I probably won't plan any long drives until the fall... Anyway, I filled up on the way home and voila, 14.7 MPG!! Earlier in the week I went over to the engine builder again to 'update' him on my tuning progress. He got the hint and next time he'll tune the carb for me, or at least check my work. The starter has been slow to turn over intermittently since the first startup. Yesterday it happened every crank. It would hesitate then fire up. The engine builder suggested it could be that the timing is too advanced. I doubted it since it's been doing it since the start when the timing was way retarded. I thought it had something to do with the starter getting hot. I put header wrap on the Y-pipe down by the starter, no difference and it's happened on cold startup since. So, I guess it could just be the starter failing? I'll try to check the timing again with a light to confirm where it is. I also have some minor leaks, but I'll leave that for another post when I start to address them. The dragging brakes appear to have solved itself, cool hubs after the 80mile trip. Only other issue is the driver's side camber which is still a little off. It's got that 1/4 to 1/2 deg adjustment left. I just haven't been able to adjust it without popping the ball joints out. All in all, very happy! Link to comment Share on other sites More sharing options...

Gary mentioned a bunch of times that the Motorcraft module would labor and kick back intermittently. Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted August 30, 2020 Share Posted August 30, 2020 Retard function? DSII modules have two input wires. Power in run & power in start. In start the ignition timing is retarded by a millisecond. This amounts to ~4* and allows the starter to turn over easier. Link to comment Share on other sites More sharing options...

I use an Echlin TP-40 module because ive tested that they retard in 'start' But Big Blue seemed to have an intermittent slow start/kickback condition. Gary showed on his oscilloscope what was happening. Link to comment Share on other sites More sharing options...

You can check the function of your module by pulling the red/light blue wire off the start relay with the truck running and put 12v on it. If that function is working the timing will retard, which you can check with a timing light or just notice that the RPM will drop. Link to comment Share on other sites More sharing options...
