Dyno Testing

Test 1 used the 357ci long-block, an Edelbrock Performer RPM, Holley 0-3310-3 carburetor, Hedman 1 3⁄4 inch headers with DynoMax mufflers, and a 3-inch exhaust on 91-octane pump gas.

Test 2 substituted the Holley Strip Dominator single-plane intake. All other components remained the same.

The graph reveals the major torque improvements of the dual-plane versus the single-plane intake. The curves also illustrate how even the dual-plane (TQ1) torque begins to suffer at 4,500 rpm and really tips over at 5,000 rpm. It appears that the engine experienced mild valve float at around 5,000 rpm, which is why the peak power occurred at 5,200 rpm. With stronger valve springs, this engine should push the peak horsepower to 5,800 rpm with a peak of 420 to 425 hp.
