Small Block Chevy Dynoed Combos

(Combos 108 and up!)


Combo 108.

Combos 108 and 109 come from pages 80-87 of the November 2001 issue of Chevy High Performance. Both combos use a 355 cu. in. engine with GM L31 Vortec heads and a GM "HOT" roller cam.

The only difference between the two combinations is the intake. Combination 107 uses a dual plane, which makes a little bit more torque.

Displacement: 355 cu. in.
Carburetor: Speed Demon 750 with mechanical secondaries
Heads: GM L31 Vortec
Intake: GMPP Vortec dual-plane
Camshaft: GMPP HOT hydraulic roller, with 0.525/0.525 in. of lift and 218°/228° of duration @ 0.050 in. of lift.
Exhaust: Hooker 1 5/8 in. headers with Flowmaster 2 1/2 mufflers
Pistons: stock
Rods: stock
Crank: GM
Ignition: Stinger electronic with MSD 6
Timing: 34°
Comp. Ratio: 9.75:1
MAX HP: 412 @ 5600
MAX Torque: 423 @ 4400
