Fully Built 225 Slant Six Pricing Question

"Most shops won't touch a built 6 around here, and if they do, they don't really know what they're doing."

These are the simplest motors on the planet built and designed in the last 60? years. If that intimidates them, you are at the wrong car shop or the reason is bogus.
I worked on a slant six powered car a few months ago, for someone else. I was told it had been to several shops and they were not able to fix it. Before the car was even unloaded from the trailer, I noticed several things. PVC hose not connected, accelerator pump in the carb not working, Valves clattering real bad. Found a few more things wrong after I started checking things, but nothing serious. All kind of basic stuff. But the shops today don't have techs that know anything about solid lifters, carbs, or distributors. Today, if you have an "old" car, you need to be able to fix it yourself, or know an old fart like me that can help you out. And us old farts need to pass on our knowledge, as we are moving on to the "mega shop".
