| | Melrose customer Bob Wisniewski was one of our first customers to utilize the LSx swap headers on his 1992 Corvette. Bob recently ran a 10.04 @ 138.30 with the mods listed and should be in the 9's soon with his Procharger goals listed below.
The car is a 1992 vette- Installed is a 2001 LS1 motor using C-5 motor mounts, and 4l60e trans. Straight axle installed by Carrols Rod and Racecraft with a Current Performance wire harness and a f-body computer. They replaced the Dana 36 with a Dana 44 3:45 gear ratio. Mods are Diamond pistons and rings, Eagle 6.125 rods with 2000 ARP bolts, ARP main studs, Cartek Performance Engineering ported, polished stage 2 heads, and Cartek custom cam with ARP head bolts, LS6 intake with ported and polished throttle body, 30lb injectors, high flow maf sensor, Vigilante 3200 stall torque converter, Performabuilt trans, Racetronix fuel pump, and harness. Melrose Motorsports custom swap headers with random 3" s.s. exhaust with x-pipe, high flow cats, and Cherry Bomb mufflers, ZR1 chrome wheels with M/T 315/35r/17 et street radials. This year he intends to add a Disc Procharger with 14lbs of boost, 60lb injectors, Boostapump for more fuel pressure and methanol injection. Will expect 900 crank hp with 750rwhp. With this kind of power he expects to also install a straight rear axle.
