There were two. The 238/258 Buick V6 that everyone remembers and the Chevy 3.8 that was essentially a 6 cylinder version of the Chevy small block. It was a 90 degree V6 with an odd, offset ground crankshaft that gave it a smoother idle than the Buick odd fire V6. The crankshafts were weak and it still idled a little rough.
I had two of these, one in an '80 Malibu Classic and one in a '79 Malibu wagon. Both played out prematurely. I replaced the one in the '80 with a bored out 454. It was IMPRESSIVE! 400 turbo trans and a 12 bolt out of a Camaro. Really IMPRESSIVE!! The wagon got a 350 small block with a 700R4. It was a great driver. You couldn't stuff an inline six in either of them without hacking all the way back through the dashboard.
Those cars were just made for a V8!!
