I thought only my wife had those kind of days. She 's been going off on me for 40 years ! moparguy, I know you don't like some of my explanations. But here I go again.
Mechanically, all V8 American engines are the same. They all have heads,valves, timing covers, cam shafts, water pumps, oil pans ,oil pumps, fuel pumps,distributors,intake manifolds,harmonic balancers, crankshafts, connecting rods, pistons, rings, blocks, exhaust manifolds. etc... So basically ( I hate that word) they all function the same, air/fuel in, burnt gases out. Just an air pump really. The point is, what you learn about one brand of engine applies to any other brand as well. The differance is all personal opinion. We know Mopars are the best cause my granpa, and father wouldn't lie to me !? Just kidding. the same tools will work on any other engine you will work on in the future.
I spent half of my highschool time in all the shop classes that my highschool offered. Wood shop, metal shop, auto shop, drafting. This education has served me well. My first job was working for a muffler manufacturer, That is where I honed my welding and fabricating skills, I worked in Costa Mesa as finish carpenter on upscale luxury boats, Good pay, but fiberglass dust and epoxy fumes didn't do it for me. I finally settled on turning a wrench for a living. A good living, you get to know the nuances of different makes and models, Eventually went into Management. My finger nails stayed cleaner. I have gone back east to the big auto and tire manufacturers factory training schools, and have a lot to offer information wise.
If I sound like I am getting too rough on you, let me know and I will back off, but remember you are not the only one reading these posts. Some people like to sit back and let the other people ask the questions. The info is for anybody that wants it.
