  1. Need an exhaust Log for L36

    Am finishing up another's project of L36 into Datsun 510. The thing is running, but I need to get the exhaust system cleaned up, because there it zero room in the engine bay. Looking for either a cheap header to chop up and turn into a log, or possibly a log that would fit. I believe a header...
  2. Twin turbo or Single Lesabre

    Hey so Ive been playing with the idea of after college putting turbo(s) on my 2000 Lesabre N/A. First off i was thinking of grabbing a newer 3800 before i turbo it.

  3. Surging at 35-40mph?

    DTC's, Problems & Troubleshooting
    Like the title says, my car is surging between 35-40mph ONLY, and I have no idea why. I did a few things before this started happening and I don't know which could have caused it (if any). Basically, I redid all but the head gaskets, cleaned out the throttle body, ran some Seafoam spray through...
  4. L36 and L67 Compression Ratio/Octane?

    Fuel System
    What I'm wondering, is why is it that the L36 with 9.4:1 compression requires 87 minimum octane, whereas the L67 with 8.6:1 compression requires 91 octane minimum?

  8. L36 tensioner replacement

    General Tech
    I just replaced the serpentine belt on my Chevy 3.8 and I had to torque the tensioner as far down as I could push it to get the belt on and it still stays down at the "bottom" of it's travel. I just about wonder if the belt is too short. The main problem now is that the belt is not in the same...
