Strapped to one of McLaren's Froude water-brake dynos, the Top Stock big-block was tested between 2,500 rpm and 7,250 (ignition system is MSD throughout). The engine was run with AC R42XLS spark plugs, Mobil 1 10W30 oil, and this timing curve: 15 degrees at 1,000 rpm, 20 at 1,500, 24 at 2,000, and 36 degrees from 2,500 to 7,500 rpm. With less than 10:1 compression, this big-block makes more than 430 lb-ft at 2,500 rpm. From there, it's a smooth, gradual progression to its peak at 5,300 rpm, where it's twisting out 597 lb-ft. As for horsepower, it's a sharper rise, from just more than 300 horses at 3,000 rpm to 657 horses at 6,100 rpm. In all it's a relatively simple, but carefully thought-out, combination that should push Monty Bogan, Jr.'s yellow Camaro into the winner's circle.
