Thread: Awesome 4.2L

  1. #1

    Default Awesome 4.2L

    I think that the 4.2 L inline 6 is one of the most powerful and best-built sixes that I have ever seen. It is very quiet and has tons of power at the same time. Awesome.

    i have to agree with philly. I have the 4.2 and it's just about the tighest engine that i have ever seen.

    first, its whisper quiet. you can't hear the thing while you're idiling. second, there's 275 horses in all that quiet.

    it's just amazing, my hats off to the engineers who designed it.

    I agree 100% I give the 4.2 inline six a big thumbs up.

    I agree with you guys. I have owned two of these vehicles and I think the engine is just plain incredible as well. Plenty of power, but still decent gas mileage for such a heavy vehicle.

    I think the 4.2L I-6 is very underrated. It's a phenom engine.

    Three cheers for the Chevy 4.2!

    I agree. I'm glad they added the starter kill switch. During the first week I onwed it I couldn't believe that I could not hear the engine running. Such a shock for an engine with so much HP.

    The starter kill feature is just a point of genius. Why didn't anyone else think of that before? I'd be surprised if we didn't see that on other vehicles in the future (or even now).

    As for the 4.2 L i6. I'm tickled pink by it. I think it's one of the best engines that I've ever started up. Lots of HP with decent gas mileage for pushing around a good-sized SUV. Two thumbs up.

    The 4.2L is sweet, I just wish they offered the 5.3 Gen III in the short Envoy/TB. The Denali is too rich for my blood.

    Looks like GM has answered some of your prayers for 2006. The 5.3L will be available in both LS and LT trim levels in the SWB TB. Still only in the Denali for the Envoy.
