At last check on the dyno, the package was producing 1,160 hp at 7,500 rpm and 825 lb-ft of torque at 6,500 rpm, just a tad more than the original six-banger. And it's not just powerful, it's stone-cold reliable as well: the W2W LS2 long-block has been subjected to-and passed-their brutal piston scuff test. (Care to try it on your engine? Bring your coolant and oil temps to 230 degrees F, then run at 5,000 rpm for five minutes, 6,500 rpm for one minute and repeat-eight times.) In real-world testing, Kurt claims this example idled forever in the Florida heat during the Hot Rod Power Tour(tm), and the coolant temp never climbed above 205 degrees F. "Man, the way it sits now, you could drive this thing back to California tomorrow without a problem," Kurt says with the sound of satisfaction in his voice.
The all-aluminum W2W 8.5:1 boost-ready LS2 has a 4.005 bore and 4.00 stroke to make 402 cid. It uses all the best parts, including a Callies crank, Howard's rods, Mahle pistons, and Total Seal rings. The main caps are upgraded to steel, and SCE O-ring-embedded copper gaskets seal the heads to the block. The Comp Cams solid roller provides 0.630-inch lift and what Kurt guesses is 250 degrees duration at 0.050 lift. Cam Motion lifters activate Smith Brothers 31/48-inch pushrods and Jesel rockers on the All Pro heads, which have Inconel exhaust and titanium intake valves. The intake is an Edelbrock single-plane mounting a Wilson Manifolds 90-degree elbow and 90mm throttle body. GM got in on the fun by supplying the timing components along with front and rear covers. Oiling is handled by an ARE cast-aluminum dry-sump pan, a Dailey two-stage dry-sump pump, and a Peterson reservoir, and ATI supplied the damper with dry-sump adapter. W2W made the aluminum valve covers in house.
Then, of course, there are two Rotrex superchargers and the trick Big Stuff 3-managed Octane on Demand dual-fuel system that allows the 9-second car to be a comfortable, reliable daily driver.
