I've canceled the Whipple supercharger and will be going with this package instead. It consists of -
Aluminum heads - compression goes to 10:1 and there is a 100lb savings over stock!
Cometic stainless steel head gaskets
ARP head bolts
New intake manifold - this is purty!
Camshaft designed for outstanding low to mid range power (not named yet)
This upgrade should be worth close to 130 horsepower and I expect to see everything in about 2-3 weeks.
2002 8.1 Silverado HD - Full Throttle lift, 37" tires, 4.56 gears, Comp Cam, TOG headers, Volant induction plus more! Heads, cam and intake manifold upgrade coming soon!
2002 8.1 Suburban -Intercooled Whipple supercharger, 22" wheels/tires + more - 407hp/558 ft-lb torque at the rear wheels - 13.93 @ 95.79 MPH
