Thanks for putting this up.
It's interesting, but it definitely skews toward the early years. Yes, it was called the Fireball at first. Then, when it came back in the catalytic converter era (1975), it was just the 231 cubic inch. And, yes, 231 is 75% of the old small block Buick 310 V8, so they did shave off two cylinders.
He's right in that the engine really got momentum when it became Series I, Series II, and Series III, but he doesn't focus much on the later and better years. And he's right that the 3.6 DOHC V6 has had problems here and there, despite becoming the new flagship V6 engine for GM.
He mentions the addition of the balance shaft in 1988 and that's when it became the 3800. (I'm at a loss right now for what a balance shaft looks like.) However, I don't think he mentioned the transition from odd-firing to even-firing, which was a really big deal and a 1978 M.Y. occurrence. The funny thing is that the bigger colonnades of 1975-1977 ran with the odd-firing V6 and the downsized ones that went from about 4,000 lbs. to 3,500 lbs. ran with the even-firing V6, which they accomplished by offsetting the journals in the crankshaft. At idle, the difference was noticeable.
I've put just about 400,000 miles on the Series I and Series III 3800s I've owned (combined). I love this engine. Throw in an odd-firing V6 '76 Regal coupe that my dad had, an '80 even-firing V6 Century Limited sedan (basically a Regal for those years) that my dad had after that, and a hand-me down Cutlass Supreme Brougham coupe with this engine ... and add rentals (from late '80s Toros and Parks to mid-90s Regals to early 2000s so equipped Impalas) and I think I might get to 500,000 miles of driving some version of this engine!
What a hoot. This was the loss leader for Buick mid-sizes ... the triangle rear window coupe '76/77 Century Special coupe ... stripped down and probably having an MSRP of $3,999. This has the rally wheels but they came with blackwalls and hubcaps.
Here's an engine bay with the 231 c.i. V6 pushed all the way to the back and with no A/C
That some didn't have A/C occurred enough and ensured the loss leader price, as well as a boring dashboard. But nothing to go wrong.
