Bolt on electric valves coming...

Not really as new as that article makes it sound. Ship engines have been using camless technology for over a decade (like the Sulzer FLEX series of engines, although other have followed suite).

Cummins, Caterpillar and Ford have all had camless engines. It works, but so far usable RPM range is an issue. Similar to why electronic diesel engines and now DI gas engines have a similar issue at higher engine speeds. You run into latency and rate of injection issues. At least with a gas engine you can crutch the problem by running both DI and port injectors.

It would be really cool if they could actually make a camless engine live and make power at 6+.

As an interesting aside, Cummins also had a small fleet of engines that did not use any coolant a few years ago.

Another option besides machining the damper is to buy a tone ring with a spacer and bolt that to the damper so you get a good signal. You can get entire tach kits from Destroked or DieselConversions. Or you can get a free pattern all over the interwebs and have you friendly local sheetmetal shop waterjet one for you.

I usually use the OEM tach on diesel swaps I've done or aftermarket gas tach's if I need to add a tach (especially for a Cummins swap) so I've never used that Autometer diesel unit before. If you check the sensor output directly with a meter or preferably a scope do you get a clean signal above idle that way?

It's a diesel specific tach, so is it using a standard mag pickup or something else? If it's a mag pickup stop by your local big truck store and buy a tach sensor or speedo sensor from there (they're about 35 dollars) although it probably won't have the same connector, the sensor will work fine.

Unfortunately I think he lost/wife thru out most of the heat/AC box part. I'm not sure and I saw him at work the other day and asked if he found any of the parts and he said he might have. At any rate, I have a parts truck with factory ac with all it's parts intact (expect for the dash panel as I stole that to put in the CrewCab since I didn't want to cut up a nice panel).

I made a patch panel to cover the hole in the firewall but I seam sealed and screwed it into place so if I, or the next owner, wants to go back to factory it's easily done and then installed an aftermarket heat/AC unit. Mostly because it just nice not having to work around the evap housing hanging over the head on the passenger side.

I just need to install cam bearings and polish the crank and then I'm ready to start assembly on the 390, but I probably won't be able to actually start on this for a month or 2 - got a few other projects to finish up first.

With the all silver door badge it's probably a 01-03. The late 99-2000 trucks had red stripes instead of silver. You can further narrow it down because 01 was the last year for the old style headlight assemblies, in 02 the went to the "jeweled" clear headlight housings.

7.3 PowerStroke is the best work/tow diesel ever put in a pickup. I like them even better than a 12v Cummins, although the 12v are pretty killer. I have several 7.3's and built and raced them for a long time. Pretty bullet proof and make decent power with a few upgrades but are very expensive if you want big power.

Some cool garages/shops in here! I also realized I don't really have any pictures of the garage or the shop themselves. This is probably the best picture I have of it from the inside as far as an overall view.

40x60 with 2 roll up doors that are too short for much of anything. This is the first time I've had radiant heat in the floor and it's nice but there is one MAJOR drawback I didn't think about before hand.....every time I have to get on the floor for some reason the concrete is warm and I just want to take a nap.

On the far left is a 2016.5 Duramax (hate working on them). My 69 C10 Suburban. My 77 F250 turning into an F450 crewcab and my buddy's Nova on the far right. It seems wrong to have so many brand X's in the shop instead of Fords, but all my Fords are either projects waiting to be built or they are running fine and don't need to be in the shop LoL

GearVendors are very nice. Ran them on several hot rod cars and a TON of 60's, 70's, 80's and early 90's trucks. REALLY like them in a truck with a manual because you can easily split gears (you can in an auto but splitting is sorta clunky I think and mostly not needed in a car) and it makes towing a lot nicer.

They're pretty tuff units. A planetary and cone clutch are pretty strong and also simple. I've run over 950hp thru basically stock Bravo One outdrives (not recommended) in boats and they use a cone clutch and take some serious abuse. Haven't seen a lot of GV failures, and the ones I have were mostly caused by the owner. Not checking oil, not changing oil, etc.

Thanks.

After I pressure washed it the thing actually didn't look too bad. There's one dent in the bed I'm thinking about fixing but I'm leaning towards not painting it. Really thinking about having a friend of mine paint a logo on the doors to make it look like an old shop truck and leave it as is. I've already mostly gone thru the interior.

I also like the 73/74 the most. I still have my Dad's 74 hi boy he bought new. It's half way restored sitting in one of my garages waiting for some attention. I've owned very few 2wd's, and that's sort of another reason I decided to keep it and put it back on the road.

Those are cool trucks. I have a 77 I'm currently building, and I've had a 66 and 70 before.

As much rust as that has, it's actually still pretty good as far as crewcabs go. Looks like the drip rails and roof skin are ok and those are the worst to repair and usually the first to start rusting! Cool project!

Been hanging around here for a while but just registered. Thought I'd post a few pictures of my first FE project in about 15 years. I will say it was really nice finding this forum and being able to source parts from guys who still show an interest in supporting the FE. This sure isn't anything high dollar, but I couldn't bring myself to part out/scrap this thing.

So what I've got is a 73 F250 camper special that a mechanic that worked with me gave me after he couldn't get it running right and parked it in his yard for north of a decade. I originally thought it was going to be parts and scrap but once I saw the truck in person and started loading it on the trailer I realized it was actually pretty solid. Sort of an odd build too. It's got a lot of options, but didn't upgrade some of the obvious stuff. It's a Camper Special, has the narrow upper trim but with the lower trim. It's a factory AC truck, C6 but with a 360. Has around 73k miles on it.

The 360 was ring and bearing'd at about 70k miles. Some unknown (couldnt remember and he couldn't find a cam card) hyd flat tappet, S code iron intake, 1406 carb and a Unilite conversion in the stock distributor. I got it fired up and it sound ok. So I rebuilt the carb, swapped in a known good Pertronix billet distributor on my shelf that has been a test unit left over from another project, new fuel pump and cleaned the tanks and started driving it (slowly and not too far, bald, rotted bias plias and such). Turns out other than some worn king pins the thing drives like new. So I had to save it. The 360 does have some issues. I think they missed the cam gear by a tooth and I suspect it's just starting to loose a lobe on the cam. So I'm doing a low buck .060 over 390 with cleaned up C1AE heads (just ordered the cam from Brent) to throw in it and will probably swap the C6 for a 4R70W or 4R100 after its in and tuned.

Bringing it home after extracting it from the blackberries.

It was pretty crusty. It was free but I had to take the bed full of tires!

The 360 after tuneup and carb rebuild. Couldn't resist cleaning it up a little bit.
