The lone upgrade made to the motor was a cam swap, which we tested in normally aspirated and turbo trim to illustrate the gains offered to … Turbosmart also supplied a Race Port blow-off valve to eliminate lift-throttle pressure spikes. Though the challenge was dominated by our turbocharged peers, we hung in the middle of the pack with some stout unboosted power figures.

We know from testing that replacing the stock cam on a typical (normally aspirated) 5.3L with almost anything else can result in big power gains. Single overhead camshaft (SOHC) engines have one camshaft per bank of cylinders. The results of the cam upgrade were hardly surprising, as we have come to expect big gains from a cam swap on an LS. Find out what went into the build! It stands to reason that any upgrade that makes more power on a normally aspirated motor should work equally well on a boosted one, right?
