I'm still dreaming of that 98+ Firebird and trying to put together what I want to do with it when I get one . What I want is AFM and Flexfuel both working. I know people don't like AFM because it sounds bad, but IMO, if I could get into the 30's (Just guessing; if you can get 20's out of it in a brick of a tahoe, than I'd have to think an aerodynamic car like a firebird would be able to get quite a bit better) AND put 400 ponies down, it would be worth it. I've been looking over the info on the 6.0L L76 and the 6.2L L92 engines. In the specs I found on one of GM's media sites, the L76 has Variable Valve Timing and AFM, and the L92 has Variable Valve timing. Since the L92 has VVT, if it was enabled in the ECM, the L92 would support AFM?

Flex Fuel support isn't really anything special on the engine, other than larger injectors and maybe the Alcohol sensor in the fuel line, right?

I'd also like to put either a 6L80E or 6L90E behind it, but that's another post for another time .
