My Ls mods: 2000 L, JLP 5# lower, JLP 2.7" upper (3#), s/b t-body, 90mm maf, 12" filter, JLP Diablo chip w/ agressive racing program burned for 100+ race fuel, elec. fan, stock exhaust w/ no cat convertors, NGK TR6s, 3:73 gears, line mod valve. I use F&L 111 race fuel (not a daily driver). You guys think my L is making over 400 RWHP?

 

You should be.

 

Yes. See my sig.

Oops! I forgot I trimmed my sig down. I have a 5 lber, th/body, c/b, Fast Air, and a few other mods but that's the 'heart' of it.
