Re: 71 K20 Idaho Edition

Found a local radiator and muffler shop run by a young military veteran. He spent the time explaining the different choices and what he thinks will work best for the truck. I told him over the phone that I needed to get the old system on the truck so I could drive it down there to get the new one installed. I explained that the new ram horn exhaust manifolds are larger 2.5 inches versus the old ones that were 2.0-inch outlets and that the old exhaust flanges will not work. He said to take some measurements and bring down what you can. He hooked me up with some temporary flanged pipe and flange fittings, donuts, and a few other goodies to get me back together for $20 dollars. The truck will have 2.5 piping from both sides of the motor collecting into the muffler and then 3" from the muffler out.

This is the mess I ended up with and it bolted right up again. I welded the new flanges to the old pipe from the inside. Then after looking at the larger side I noticed when I was done I forgot to slip on the flange for bolting it up. So I had to cut it in half again on the new stuff and slip the flange in and re-weld for the second time. Took about 45 minutes to do the fab work and about another 30 minutes to install under the truck.

Now I just need to run one new wire from the fuse box that is on during the start and run to the new Flamethrower coil to power up the Pertronics distributor. Install the z-bar for the 4-speed shifter linkage. Plug in two or three other items and I should be able to fire it off tomorrow. If that all goes well I will be painting over the weekend and bolting on parts.
