Hey, I've been thinking about how many cycles/versions the 3800 V6 has gone through. I can come up with these:
1) original version developed by Buick in the 1960s (sold to Jeep and then bought back)
2) 1970s version, returning in 1975, adapted for unleaded fuel and updated distributor/electronic ignition (odd-firing) (105 or 110 hp)
3) 1978 version, crankshaft journals are offset (becomes even firing) (105 or 110 hp) - remained well into the 80s, powering GM RWD intermediate series such as Cutlass Supreme, Regal, Grand Prix and Monte Carlo (though Chevy 4.3 V6 powered the latter two toward the end of their lives as RWDs)
4) 1985 version, modified for FWD, powers the FWD Olds 98 and Buick Park Avenue/Electra down-sized full-sizes, and used again in 1987 for the new Pontiac Bonneville but not yet called Series I (about 150 to 165 hp)
5) 1990 version, through 1994 (Series I) - has received the tuned port induction system (about 170 hp)
6) 1995 version, through 2003 (Series II) - weight reduction, crappier intake manifold, and increased horsepower (about 200-205 hp)
7) 2004 version, through 2008 (Series III) - powder coating of metals, revised and stronger intake manifold, and electronic throttle control (about 200 hp)
Am I right? Is it a total of 7 versions since its inception? It looks like Series I and Series III are considered the better versions. Comments?
