A word about "crate" engines...and marketing...
19201992 - LS3 = 430hp (204*/211*, .551"/.522")
12594727 - LS376 = 480 hp (SAME Heads/Pistons, 219*/228* .525"/.525")
19259233 - LS376 = 525 hp (L92 Heads, 226*/236* .525"/.525")
Slightly different, non-CNC'd heads and a longer duration-but-lower lift cam = 95 hp? Over a base Corvette LS3?
Really?
