  • L67

    Can anyone give me any information about a 3.4L L32 to 3.8L L67 swap? What fits, what doesn't, what parts still work, what needs to be new. All that good stuff. And yes I've seen/heard in every post when someone asks about a motor swap that an LS1 is just as easy/hard. I was just wondering if anyone has any input on this.
    Transmission? Wiring harness? Computer? Power steering pump? Exhaust? Starter? Alternator? Oil pan fit? Mounts? Anything else?
    Any advice is appreciated, thanks.

    IM pretty sure EVERYTHING would have to be new. The 3.4 and 3.8 arent similiar at all from what ive heard. I dont think anything from a 3.4 works with a 3.8

      Most definately needed is a complete motor, wiring harness and PCM and exhaust manifolds.

      Doesn't seem worth it at all.

      You might be able to get away with the trans, not exactly sure on that one though.

        Need the engine but also stuff like the wiring harness, pcm, and custom exhaust.

        I have seen a 95 Firebird GM car that had a L67 in it, you would need a higher hood to clear the supercharger.

              Umm.....I think NOT. There is alot more than just a SC on top.
              Run a search, and you will find more info than I can even begin to start with on the differences between the two.

              Just a SC....yea...lol
