I completed a few minor tasks. After some debugging it was determined the 100,000 hour LED high beam indicator light simply burned out. As a generous estimate it may have provided an hour or two of illumination over the last several years. I don’t drive that much at night and the high beams are seldom needed. I guess the longevity promises are to be taken with a grain of salt. In any event I now have a new indicator light in place that works fine.

Next I addressed a rattle that’s been annoying me since the new engine went in. Because I have both an electric speedometer and cruise control, the hall effect drive units connect to each other off the speedo drive of the transmission. If they aren’t tethered correctly a rattle occurs with the transmission crossmember. When the transmission went back in I just didn’t get around to securing the parts against vibration. They worked fine but were very annoying.

While I was under there I noticed a minor leak and realized the pan and valve cover fasteners all needed to be retorqued. So that’s done too. The only thing left on the list from the engine change is to recheck the ignition timing. That an trying to convince my wife that electric exhaust cutouts are really a better investment than a dual quad supercharged big block. So far I don’t think she’s grasping the importance of $500 cutouts!

And this morning I completed my final new engine adjustment. This is the first time I’ve ever owned a degreed balancer, so I had no expectation a stock timing tag wouldn’t work. Once assembled, it was immediately apparent the standard aftermarket bolt on timing tag is too big and too long and covers up all the damper markings! Watching a couple of Youtube videos I realized there are timing “pointers” on the market, mostly in the $30-$40 range.

So I did the next best thing. After removing the power steering pump (again) I pulled the tag, marked it up, and cut away everything that didn’t look like a zero pointer!

Here is what was cut away with a Dremel tool:



What was left got reinstalled as a zero pointer. I didn’t think to take a picture of it before mounting it back on the engine:



I knew I had too much advance in the engine, but I couldn’t tell how much. With the new pointer in place it was obvious I had almost 20 degrees initial and 50+ total. After spending a few minutes repositioning the distributor, the initial is now set at 10 degrees and total comes in a 34 degrees. What a difference in how it runs and sounds. A nice hour long investment in making the engine run better, and being able to repeat the settings in the future. Of course now the idle is even rougher than before, and idle vacuum dropped from 12 to 10 inches at 650 rpm. Man this is getting to be fun!!

This shows nothing more than the new Moon sticker on the heater block off:



I took the truck out for some “acceleration testing” with the video camera, but today is Saturday, the day after most of the schools closed/graduated for the season. Meaning – there are cops everywhere! :lol: not a good time to be checking performance improvements. When I pulled up to the corning in my earliest Youtube video, two police vehicles already had somebody pulled over right at the turn! When we went out for gas last night there were at least 10 police cars cruising, parked, and hiding on the trip. So I think any new video adventures will have to wait a bit.

Great story on the truck Mark! Love how it seems to keep evolving.

Well I put up a couple of rather mediocre Youtube videos this morning. I made a couple of goofs and forgot to mention a bunch of details, but they somewhat show the truck and its features. The 1st one is mostly inside and the engine and the 2nd one is just the outside:

Great video Mark, that is one sweet truck, you and I think alike, more into the old school...

Sweet walk arounds. It looks fantastic!

I think I agree with your wife, a dual quad blown big block is better than cutouts - if you have to choose.

Well I got to choose, but the supercharged big block was never really in the running! So I've gone and jumped in again. This morning I spent a while under the truck figuring out where I could install electric cutouts. Finally figured out an arrangement that will fit and work, so I ordered a pair of Doug's units from Amazon at a $50 discount over Summit or Jegs.



They will be mounted outboard of the frame and have short tail pipes that exit in front of the rear wheels right under the edge of the steps. I'm not too worried about exhaust build up on the rear wheels as the cutouts will mostly be used at rod runs and car shows during slow speed driving.

If it comes out as I envision, the modifications should also add a nice feature to the exhaust system which was beautifully crafted by my local muffler experts.

Other than being a lot of hard work, today was a fun day. Really fun. I had a smile on my mug virtually all day. My electric cutouts arrived yesterday so I immediately made an appointment to have them mounted first thing this morning. So, at 08:00 the owner of Discount Muffler in Spokane (corner of Sprague and Argonne) spent a little over an hour and a half this morning creating more of his exhaust art. He custom fabricated a pair conventional cutouts welded into the exhaust system, to which the Doug’s electric cutouts were bolted. He also suggested I pick up a pair of copper exhaust flange gaskets as they don’t leak or burn out, and are reusable. Per his suggestion I picked them up last night. He was concerned about the weight of the cutouts (about 5-6 lbs each), so he doubly reinforced the welds and also added a support brace under each side.

The results are incredible. If I wanted to go somewhere and really look old school, I could just remove the electric cutouts and cap off the sneakers. But that’s not likely to happen as the electrics are just too much fun. It took me another 5 hours to route the wires into the cab so they were nearly invisible. Of course the wife immediately wanted to go for a ride.

All I can say is these things are a blast! The truck doesn’t have that “worn out muffler tractor sound” at all. At idle it sounds plain nasty. At speed, it reminds me of a 1960’s stock car racer, whether up or down on the pedal. Sadly none of our video today turned out well enough to post on Youtube, so I’ll try again tomorrow.

And the cutouts themselves are as nice as advertised. It only takes a bit over 1 second to go from full closed to full open. And the same speed going from open to closed. Here’s how they look from under the hood:





And they are reasonably well hidden. They are only visible from limited viewing angles directly to the side. There is clearance all around them, and the lowest parts are a couple of inches above the bottom of the lower control arms, so there is plenty of clearance even over speed bumps:





I’ll try and have some video up tomorrow.

Well here are the best videos of the exhaust cutouts my wife and I have been able to capture so far. The first one is from the in cab camera, and I only have the cutouts partially opened so they wouldn’t overwhelm the microphone. It’s pretty boring, mostly just the engine idling. I also discovered either my aircraft clock timer runs fast or the camera timer runs slow. As a result I shut the engine off too soon.

http://www.youtube.com/watch?v=g9f0C...ature=youtu.be

The 2nd video was taken next in sequence on the tripod camera.

http://www.youtube.com/watch?v=JPMAZ...ature=youtu.be

Until about 45 seconds the cutouts are only partially open. They are wide open for a while and then back to partial again. The difference is pretty obvious. On the cab camera of the same sequence (which I’m not posting), the partially opened revs sound fine, but the fully opened revs blow out the mike. In this second segment there is so much background noise the idle sound is almost absent. That and I moved the camera too far away to successfully capture the idle sound, in order to avoid having the open exhaust blow out the mike on the tripod camera.

I just love how fast this engine revs and immediately drops to a rough idle of 550 rpms with no tendency to want to die. I’ll try to capture better video/audio again, but it’s going to be over 100 degrees here tomorrow so it won’t be for a few days.

I rewarded my squeeze with a trip to the ice cream place. In addition to capturing some video I wanted to test the new engine’s ability to tolerate idle traffic in high temperatures. The old engine always overheated above 85 degree temps unless I could keep it moving. Being trapped in traffic was not good. The new engine sat idling for almost for almost 25 minutes in 90 degree heat and maintained a constant 187 degrees on a 180 or 185 degree thermostat. There’s a local rod run this weekend and now I’m confident we won’t have any problems in the cooling department. WOOHOO!
