I appreciate the continued reponse guys.
I've taken a closer look at the 3.8 engine. Boy, it's real basic : push rod engine with 2 valves per cylinder, single camshaft and a cast iron block. But, apparently reliable and long-lived as heck. A radical departure from my all aluminum 200 hp, DOHC, 24 valve, 4 camshaft, 2.7L V6 with 3 timing chains that needs constant vigilance and periodic expensive preventative maintenance.
It's interesting comparing my Intrepid to the Grand Prix w/3.8 :
Both engines produce 200 hp and both cars get close to the same gas mileage (possibly better with the Grand Prix). I get my 200hp and mileage from a modern high tech design, smaller displacement but higher volumetric efficiency (74HP per liter). But the price is much higher mechanical complexity, the need for expensive oil or high frequency of oil changes, and high cost periodic maintenance (we're supposed to replace all 3 of our chains and tensioners - plus the internal waterpump - at 100K miles. Typical prices are $1500 to $2000).
With the GM 3.8, I would still have the same H.P. but from a larger engine with lower volumetric efficiency (52 HP per liter), but the older simpler proven design means long life with standard maintenance practices and costs. And I would still get the same gas mileage, but none of the worries that I have with the Chrysler 2.7.
It's startin' to look reeel clear. Althoughhhh....the 300M with the more reliable 3.5L is a pretty nice car too. Hmmm.
