How about an Old School Truck, can anyone guesstimate what a '95 GMC Sierra ECSS with the following mods would run:
Truck & Driver weighs 5100 lbs
381 cid Gen 1 SBC 4.020 x 3.75 w/5.7 rods 10.8:1 CR
Revised Late model L98 Alum Vette Heads, 58cc, 165cc Intake, 1.94/1.5 valves
Crane Flat Tap Cam .210/.216 - .440/.454 @ .050 114 LSA, Crane 1.5 steel Rockers
Edlebrock Performer TBI (bored to 52mm x 2) Intake Manifold
Holley 670 cfm 52mm x 2 TBI with 65# Injectors
GM HEI, MSD Coil, MSD Wires, AC Delco Platinum Corvette Spark plugs
Pace Setter Shorty Headers, No Cat Single 3" to Dual 3" High Flow Muffler

93 Octane pump Gas
Fresh Motor in '10, before rebuild I have some track times but not a single one after.
