Blown out exhaust manifold (and tach)

So this is the vid of my manifold after its patch blew out and my tachometer at its best (7000 rpm peak)

Long time no Post

Well it's been a long time since I've posted something so i just thought I'd put in a quick update. Two weeks ago the timing went out on the truck so we replaced the ignition coil and points. The ignition coil is a MSD Blaster 2 the truck is running great so far. Next thing on the to do list is exhaust fixing and new mufflers fix up the carb, new steering wheel , paint and interior.

Fixing the Mega Leak

After the massive hole in the exhaust manifold we went to go buy some exhaust system sealant. We didn't expect it to do much but I'd have to say it worked pretty darn well. The engine is silent (except for 1 noisy lifter) it's wonderful. Pictures soon

Mega-Leak Manifold Monday

Yes, I know its tuesday BUT! I took these pictures yesterday ha-ha. Anways on to the leaky manifold. As most of the people who have seen and heard the truck know, it's louder than most other trucks. We've known we had an exhaust leak since day one and I quote "Hey dad I like the sound of the truck!" Dad:"It's an exhaust leak" Me:"Oh.... Oh well still sounds cool". Anyways on with the story. We thought the manifold was either 1. loose on the block or 2. had a bad gasket. What we saw when we took off the heat riser was quite a shocker (I'll post a before heat riser removal and after). There was a huge crack in the manifold!!! HUGE! The only thing keeping it quiet was the darn heat shield which was burned to a crisp.

Hub Cap Cleaning and wheel hub painting

Long time no post yes I know. A couple weekends ago on a nice sunny day I decided to clean my hubcaps and paint the underwheels after about and hour or so this is what I got.

Radio Magic

Yesterday (March 16th,2008) my dad and I took a ride in the truck. While riding around I got bored and decided to fiddle with the radio. To my surprise it turned on! It never ever ever turned on before and I had just about given up on it, but it lit up no sound but it lit up. When we arrived at the house we turned off the truck and put it in ACC and turned the radio up as high as it would go and there was.... SOUND!!! not loud barely audible (bad speaker I'll fix it this weekend) but it was working pretty exciting if you ask me.

Testing the Truck

Today I took a good look at my truck and after reading my 69' Service manual I decided to take a look at my air filter. If you can see in the photos it's a bit different it's equipped with a heat stove to make sure all air coming in is above 100 degrees F. It is run by vacuum a thermostat decides to let vacuum through or not depending on temperature. It should let vacuum through at this temperature but would not, so to get past this I bypassed the sensor and hooked it straight to the vacuum motor. Lo and Behold it opened correctly but shortly after I heard an audible POP and it had closed. Looks like I need a new vacuum motor and sensor. Let's call Delco AC! they can help.... not. Anyone got any ideas what I should do? It has an exhaust leak on the left manifold, so if we replace that we can get a regular manifold getting rid of the heat stove, which would let us get a new carburetor. Time to go ponder the great ponder-able
