Fun with Ted, Todd, Bill and Paul…Resurrecting an Ultimate Rebuild.

[L98TPI]

Front seat? FRONT seat? That's what the third seat way in back in the Burb is for, the "Are we there yet?" kids!:rof: Kinda reminds one of National Lampoon's European Vacation "Look kid's, Big Ben and Parliament!":hihi:

The 3rd seat in a Suburban, or any wagon for that matter, is for the mother in law, and even my mother when she is getting on my last nerve. Family harmony and what not. :hihi: I wonder if I could fit some ejection rockets to it.

Or just not engage the floor latch and leave the rear doors ajar. Punch it, the seat flips over and out she goes!

No Bro. The roof rack is for the Mother in Law!!!

Roof Rack for the Mother In Law...some would need a tranquilizer gun and a crane to get their's up there.

Back to the truck motors...you know...the tread topic.

635R - Harland Sharp or the Peninsular Roller Rockers will not compliment the Heath Cams unless the push rods were shortened to make up for the increased multiplier. The reconditioned "Uncle Bob's" rockers with brass buttons should do the job nicely in the meantime and have been ordered.
Still waiting on: Joe's Grinding of Yakima to let us know the block is good and ready for use, wrist pin bushings to arrive so they can be set in, and the Uncle Bob's rockers to arrive.

Ted's 6.2. He's got the 6.5 heads, turbo, intake and exhaust manifolds from yet another source along with a PCM and some other assorted parts so once his cross-over pipe gets in and some machine work is finished he should be ready to go.

Update:
I don't know for sure what the schedule is now past Todd getting up and running. Reasoning is, I finally got hired and to a great job to boot, so my ability to just head out and do something with only $$ as a limiting factor has changed. I have sufficient funds coming in now but not the time to take off whenever or for however long I like. This is actually working to an advantage as the plan kept "slipping to the right" with supply and service providers experiencing extended delivery times. Add to it, the machine shop has been so slammed with work, the Diesel Depot block is STILL NOT DONE! Meaning it hasn't been dipped, Fluxed or the Main Bore Centerlined (I think I got that right, my head is still spinning from an hour of tech talk with Bill yesterday).

In review:

Originally the plan was to have come to completion by now with Todd's motor completed, installed and running flawlessly with an HT#4 Cam kit and specific Max E Tork Tune. Once his was finished, I would road trip up to Ellensburg where my 141 block motor would get pulled on a Friday/Saturday; cannibalized of starter, IP, Lines, Injectors, Water Pump etc to complete the rebuilt "635R" that will still get the HP#3 Cam kit and Max E Tork tune. It would be dropped in on Saturday/Sunday and buttoned up with a few runs on Monday to ensure something wasn't left out/loose. Monday would also give Bill some experiment time with adjusting tunes to this 'very not stock motor' if desired. Ted's motor would receive the heads, turbo, exhaust and intake manifolds plus other parts off my old motor to complete his build with the HT#4 Towing Cam and Tune. If time permitted and patience hasn't fully waned, Ted would then pull the little 6 banger gas burner from his 81 SB C10 and drop a 6.2 mechanical N/A with the NA-66 Cam Kit.

Well, it looks more like this now:
1. Todd's motor, delayed by the waiting for the backlog of "New" Stanadyne IPs to clear out (not sure if he got one or gave up) and also having given up on finding a serviceable set of heads in the shop, ended up ordering new from Peninsular....anyway, add those types of issues to all the other stuff life throws at us...he's finished the build and will install it this week with Ted's help.
2. Ted, having too much time on his hands to search Craigslist for 6.5/6.2 parts while waiting, has amassed enough 'stuff' to the point where my motor is no longer needed to get him up and running. With delays in my schedule, he is bumping me to the back of the line while he decides if he should start an internet 6.5/6.2 supply business. I digress...His will probably be completed in the next couple of weeks as long as his fingers remain crossed. He'll then install gauges, extended range fuel tanks that double as running boards and generally get ready to roll wherever and whenever he pleases.
3. Still waiting on the outcome of the block, I will head up there anyway in the next couple of weeks leaving late on a Thursday (burning comp time). I'll be delivering lot of spare motor parts I've received from OrionThade to add to the collection of stuff they have and may end up just leaving my truck there in the capable hands of Todd and Ted. Before winging home, I'll spend a couple of days alternately pulling parts from the old motor and driving the piss out of Joe Heath's truck with the HT#3 and HP3 Tune. Bit of a bummer that I won't be able to be there for the assembly and all but, Todd is going to take his sweet time and apply an extra helping of his already meticulous nature to the build. Hard to schedule genius, so its best if I just stay back, with my hands off the torque wrench. I'll return when the motor is ready to drop in so as to be of "help."
4. Ted's N/A 6.2 conversion may wait a bit...or not. Depends. He's feeling road trip fever again....

More to follow, time to do some chores.

Thanks for the update. I have the opposite problem, PLENTY of time on my hands, NO money to do anything/go any where/buy anything. Using public WiFi to communicate with the world and donating plasma to keep the cell phone on and the lights glowing. I suppose, since all the new parts are laying around in the garage and elsewhere, I could put the new heads on my '94 6.5TD, get it running (needs two new batteries) and sell the beast. It's a perfect set up for a welder (original use for the truck) or carpenter with its Rawson Koening steel utility box on it. It's a former Texas truck, pretty clean and still a looker.

If you can order the harland sharp rockers in 1.5:1 ratio then you could still get the benefit of roller rockers with any cam. And shorter pushrods doesnt make too much sense to me, you'd be messing with the valve lash wouldnt you? They come in 1.6:1 ratio for anyone with a stock cam to get a little more lift and duration, but might be able to do any ratio.

You're right. Shortening the pushrods won't change either the lift or the ratio of the rockers. Only changing the location of the rocker fulcrum will change the ratio and effective lift. Shortening the pushrods only opens up a whole different can of worms with clearance/lash/free play problems and the most likely destruction of the lifters and rockers.

I doubt they have 1.5s it would have to be a completely dif rocker

Monday am Todd's engine will be going in his Blue GMC. Everyone will still be on the phone taking orders and talking to customers about the things they need. Everyone is looking forward to Todd's Blue pickup getting back on the road. With Todd, Bill, Joe and myself working on it, it should be in and bolted down AND close to running by days end!

My towing cam should be here by the end of the week and then my 1982 6.2 with 'brand new' GEP heads, and Clevite bearing will finish being assembled and stuck in the engine compartment of of my green dually.

Take some time and install the 'custom made' aluminum running board fuel tanks. These were custom made 'just' for an extended cab dually Chev/Gm. They flair out towards the duals. And hold about 44 gallons each and hopefully they will work well. The tanks are about 4.25 deep, in case anyone is interested. They bolt onto 1/4" thick 3" x 1 1/2" channel iron. The channel iron bolts to the 3 specific holes at the bottom of the frame. They aren't down low enough to completely cover the frame that can been seen from the side. With the 265x19.5 tires the tanks should still have plenty of ground clearence.

Paul will bring his pickup to Ellensburg and Todd and I will do his installation and that just might be it for a while!

My 2WD 1981 SB, with 3:08's, and an A833 overdrive trans can wait a little longer for the 6.2 conversion, maybe!

 

[Husker6.5]

Can't wait for pix of those dual tanks. Perhaps a set to fit Suburbans in the future???? I'll volunteer mine for test-mule status.

 

[Paveltolz]

Send me some shots of the work party Monday and I'll post 'em up.

These were custom made for an extended cab dually. A little over 9 inches wide and then they flair out and meet up with the width of the dually fender. They tuck up almost tight to the frame and the inside edge is tapered to fit the body/frame mounts. I followed the truck they were on, for a couple of years, before the last owner took them off and put them up for sale. They both have gauges in them but will need a pump installed to fill the main tank. I will be using one of the tanks for fuel and the other for water, WMI uses about one gallon of water to one gallon of fuel.

Thats a lot of water! What size nozzles do you have on there? I would worry about using a lot since it increases compression, cylinder pressures. Mine didn't run constant and I have two small nozzles, so I only used about 1 gallon of water to 10 gallons of fuel on a long ride a while back.

I am only using one stage of the Snow WMI. And that is just a #7 nozzle. WMI is set to come on at around 6 pounds of boost. The road trip the 3 of us went on was when I found out the water use. A 32 gallon water tank and a full tank of diesel and both just about out at the same time. Could really tell when the Water ran out from the less amount of power on hand.

Maybe you should increase your use a little more.

 

[buddy]

I dont need the water for power My ride is pretty lite and dont spend that much time with 6psi of boost, just on grades or acceleration. So the one time I spent half a day driving up the Rocky Mts, I used a little more water.

Do you know if that is 7 GPH, or what #7 means, and how much pressure do you have on the water pump?

I also dont want to use too much to increase the cylinder pressures. Just enough to drop IATs a bit, and that it did.

 

[635]

Well the pump is the newer Snow pump, before Bill Heath came out with his new WMI. He had set mine up, after a little experimenting, and it does seem to work quite well.

A # 7 nozzle.

Don't need the water in cold weather. Just used it at higher rpm's and we were running the engine a very high rpms quite a lot of the time, if I recall correctly!

If something would of broke, I would of just blamed Limey, even if it wasn't his fault!!

There's some clarifications on driving styles and druthers that need to be brought up cause its now apples and oranges with regards to usage.

Ted tends to maintain around 62mph, which, with the ATT set up he had for a while, didn't boost high enough to kick in the WMI. Which, I think, is the valid point you're bringing up as you're still running the ATT and, therefore, lower boost and less water consumption.

Even at 65 or 70, unless on a grade, the same ATT put on my truck wouldn't be producing the 7lbs boost to get WMI kicking in either, which is the minimum for the Snow to kick in (Ted, correct me if I've got this one wrong). That's actually a good thing MPG wise, a credit to the ATT and other larger turbo's and another discussion too...:agreed:

The road trip referred to, we were running the GM-8 again only we were driving at 75 - 85 (+) to make time (link posted earlier in this thread). We all realized that the ATT would have been of great benefit at those speeds. However, at 62mph, the GM8 with the WMI running at whatever the consumption level is at that speed, IDK, Ted's fuel mileage was 23mpg with WMI alone...one ton dually, 30 gal water, 25 gal propane tanks, etc.

Picture is Ted's truck at the Custer Battle Field, sunset. Great trip.

 

[buddy]

My MPG was about 24 or 25MPG on the longest trip I took, a 2000 mile trip one way, which I used up 8 gallons of propane that I didnt refill along the way, and refilled the water whenever I stopped for fuel, but I can carry 84 gallons of fuel with my auxiliary tank, so I use the water sparingly between fuel stations I suppose. It definately helps on grades.

 

[Paveltolz]

25 mpg is great. Best I got with the ATT was 20.3 but my truck is a K series where you're a C, and I wasn't running water or propane. Still not. I would have liked to see what we would have gotten on that trip with an 8700lb payload at 62mpg with water, propane and the GM-8 but, other than bored, we knew the one thing we would get was way behind schedule. However, as Ted mentioned, when the water went dry, we knew it immediately .
