quote:The 3.8L is one of the longest-lived engine designs ever. It has, during it's GM tenure, appeared mostly as a 3.8L (231 cid), but has been made in both the 3.3 and 3.0 shorter-stroke versions. During the late 60s, early 70s, GM had actually sold the tooling to Jeep/AMC (I think it was them...), but later bought it back. It first appeared in production as a V-6, 198 cid version in 1961, 44 years ago (easy for me, since I first appeared in 1961!). But the supreme irony of this engine is that it was developed from, of all things, an experimental all-aluminum V-8 that GM was toying with during the 1950s, hence the 90 deg design. To get to market with a V-6 fast, they chopped this engine, made it from the easier iron, and the rest is history. As a result of the 90 deg bank angle, it suffered through being a Harley-like uneven firing interval engine for several years until they fitted it with a split crank pin crankshaft. Turned out to be a pretty good engine, but you'd hope it was good with 40+ years of development.
3800 is a Buick engine. 305 is a small block Chevy, completely different machines. The 3800 might be similar to the small block Buick V8.
quote:You forgot the other half of the story sir. It was a two way deal between Honda & GM. I don't know the details, but GM received the Honda 3.5L V6 for the Vue and Honda received a number of diesel motors from GM. Like I said, I don't have the details, but I'm sure somebody else around here could chime in with some.
ROBBOBSTER: Yet with all of the V6 engines mentioned, GM still buys 3.5L V6 engines from Honda for the Saturn Vue...
