Thanks JeepSnake, I wasn't really sure about those HP ratings. I dug up that old issue of Musclecar and it has the specs on the L88 and I think I remember reading a spec book on Corvettes (when I was a Chevy man too) which posted the same hp for the L88. I really can't recall seeing a hp rating for a ZL1, but I do remember seeing 550 being the correct hp, for as you say the L88. Now that you mention it, I do remember the 450 (460 hp, 1970 Corvette) LS6 being the most the most hp advertised. Good Stuff!
