LS2/L92 Engine Package - Blue Collar Workhorse- Tech

When I left Hudson, New Hampshire, Golen was still awaiting a set of Jesel shaft-mounted rocker arms and valve covers to complete the long-block. The Jesel rockers didn't arrive in time for the dyno test, so Golen wound up installing stock L92 1.7 rockers and pedestals. Base price for the long-block is $12,495, including the Jesel rockers and the Compstar crank (not the Dragonslayer used in this test).

Using FAST XFI to manipulate the spark and fuel tables, Golen got the 402 tuned for a 50/50 mix of 93 pump and 104 unleaded race gas. Once dialed-in, he let 'er rip on the Land and Sea dyno (after breaking in the motor using Kooks' 1 7/8 headers to vent the exhaust). When all was said and done, the totals were 597 hp at 6,500 rpm and 560 ft-lb of LS7-eating torque at 5,000 rpm. These peak rpm and totals are indicative of the streetable cam Golen carefully chose for this build. Though a cam swap could easily net an additional 25 hp (or more), why sacrifice driveability when you already have 600 hp on tap?
