We wanted a bit more power, but we didn't want to tear apart a brand new engine. The solution was to toss in a bigger bumpstick from the folks over at COMP. Turns out that GM fits their crate engines with fairly conservative camshafts. This means that tossing in something bigger, along with a stronger set of springs, can yield even more power. In this case we went with a 219/235 duration 0.607/0.621 lift 113 LSA cam and a set of stiffer valve springs (PN 26295-16). We didn't have access to a dyno, but past testing indicated that this should easily put us over the 500 crank-horsepower mark.
