  5. Turbos
    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.

  9. 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? If engines with higher compression require higher octane, then why does the L36 require a lower minimum octane? And also, why the...

    Hey guys, I recently bought an L67 with a blown head gasket out of a WH. I pulled the top end apart because I was just going to give it a clean up, replace the gaskets, then put it all back together and throw it in my VS. Wondering whether it's worth doing a top end rebuild, and if so, what...
