Front Cover: This ever-popular 496 pump-gas Oldsmobile street engine custom built for Adam Wahl has excellent street manners and an abundance of low-end torque. This particular engine has many accessories, including a March Performance Pulleys serpentine conversion kit. Inside, the engine has basic popular bolt-on parts. This engine produces 560 reliable horsepower and a whopping 650 ft-lbs of torque, which can easily spin the tires.
Title Page: The finished BTR billet tunnel ram helped make 780 hp out of Turner’s 417-ci BTR-prepared DX Olds.
Back Cover Photos
Top Left: At full lift, the pushrod is at the other side of the pushrod cup, but is fully contacting the entire pushrod cup in the rocker body. This style and shape of rocker body allows this to take place.
Top Right: CP custom pistons are manufactured accurately enough so that if you want to hone the bores to a particular size, you can then order the piston in that size. You don’t want to use a micrometer to measure the skirt and set clearance as with some other pistons. First, the skirt is not straight or round, and chances are you cannot measure the exact spot accurately. Second, the skirt clearance is set for you, so don’t reinvent the wheel and change it from the designed clearance. I have followed this method with 100-percent success.
Middle Left: When oil gets to the front of the passenger-side oil gallery and feeds the front main and cam bearing like the other four, it then transfers through that common passage and feeds the driver-side oil gallery.
Middle Right: This is a Stage-3 Batten cylinder head and can, which can be identified by the rocker stud pads being all tied in together, unlike on the Stage-1 and Stage-2 castings.
Bottom: This is the author’s 1970 442, running low 11-second quarter-mile times and chasing the NHRA E/Stock Automatic-Class World Record.
