Dave,
I'm glad you shared your experience. You are not alone.

Back in 2001, just as I was transitioning from dial-up Internet to cable, I was replacing the old incorrect small block engine in my 1963 Corvette with a new incorrect small block engine. The volume of online help back then was not as good, so I didn't realize the new engine had a different head design that changed the exhaust ports and raised the intake a fraction of an inch. That one difference snowballed into a dozen changes that each affected other parts. It seems that you can rarely modify one part on an old car without it taking three times as long and costing twice as much as expected. I've come to expect it now.
