3.5 to 3.9?

I've been looking into swapping my 3.5 for a 3.9. Might not sound like a good idea to most but that extra 30hp is calling my name lol. would I have to make any mods or will the motor drop right in?

I think the 3.5L & the 3.9L are the same block & the 3.9L just has a larger bore & stroke +.

Yes, the 3.9L is rated @ 242 HP..

Have you found a 3.9L ? Any prices ? Good Luck!

2006–2007The facelifted 2006 Monte Carlo (and the companion Impala sedan) was introduced at the 2005 Los Angeles Auto Show. The base engine was a 3.5 L V6 producing 211 hp (156 kW). Trim series for this generation include the entry level LS, the mid level LT, the upper level LTZ and, the top of the line SS. The most notable news, though, was the SS model's use of the generation IV small-block V8 — the first V8 since the 1988 model. The 5.3 L V8 produced 303 hp (226 kW), which raised some eyebrows considering the fact that it was being placed in a front-wheel-drive car. The interior for 2006 was mildly redesigned.
