Viper Tires on CSX3170

What engine are you turning 9300 rpm? Yeah running without shifting is the way to go. You running a carburator? I have a TBI by Holley I am planning to install. I have a cam that will give nearly all its torque at about 1800 and pulls right up to the limited 6500 rpm limit.

It is a Shelby FE block with Blue Thunder heads 440 cid. Fast XFI port injection, Sonny Briant crank, Carrillo rods, Dailey dry sump, 15 to 1 CR, Chevy mains and Honda sized rod bearings, MSD ignition, titanium intake and exhaust valves, really good valve springs and a cam with .818 lift and over 287 degrees duration at .050. 820 hp @8200, 790 @9000 and 562 lb/ft at 7500. Over 430 lb/ft @ 3250 so not bad on low end. Wilson 1650 cfm Throttle body on Victor JR highly moded manifold. Headers are 21/8 ' primaries with 31/2" collector. One reason I destroked this engine was to kill low end torque. Too much low end torque just results in wheel spin and that slows the car. Soft cut is 9300 hard cut is at 9500 rpm, we have seen 9400 numerous times.
