Motivational sent the 454 to Contemporary Auto Machining in Huntington Beach, where master Yo applied his accumulated knowledge. Yo did all the requisite tampering and lightly punched the seasoned four-bolt main '70 block 0.030 inch, turning it into a 460. Back at Motivational, the Saikis jumped on the factory crank and put it up with dimpled connecting rods fitted with 7/16-inch bolts. On top of them are forged pistons that yield (along with the combustion chamber configuration) a compression ratio of 10:1. The Saikis had Isky cut them a custom profile furnishing 255 degrees of duration at 0.050 and a heady 0.715-inch lift. Then they put it together with a Cloyes double-roller timing set. At the bottom of the block they affixed a 6-quart Milodon pan and a Mellings oil pump.

The 049 cylinder heads went to Dr. J's Performance in Orange, California, for copious spiffing. The Doctor ported and polished and put 2.25-and 1.94-inch valves in the sparkling pockets, then completed the valvetrain with Isky springs, roller lifters, hardware, and 7/16-inch hardened pushrods. Thrashing on top of it all are 1.7:1 roller rockers. Meanwhile, Dr. J massaged the Edelbrock Victor Jr. intake manifold for optimum flow, as well as the Holley 850-cfm carburetor tweaks.

To complete the setup, the carb was fitted with a 4-inch K&N filter. Hooker Super Comp headers with 2-inch primaries scavenge the cylinders and feed into a 3-inch mandrel-bend system fabbed by Motivational. For plenty o' spark, the MSD Digital 6 box and Pro-Billet distributor set a serious fire in the hole.

How'd she do? The 460 proofed at 562 lb-ft and 597 hp. Despite the subterfuge in the cockpit, a manual-shift Turbo 400 transmission prevails. Steve Sharp in nearby Torrance is responsible for the build, combining his expertise with an Edge 9-inch converter (4,200-stall). Motivational modified the B&M Quicksilver shifter using an original stick-shift lever (and dummy clutch pedal). Grunt passes down a steel driveshaft produced by Cook's Machine Works in Los Angeles. Cook's also narrowed the 12-bolt 1/2 inch on either side in preparation for the Tom's Differentials 33-spline axles, 1/2-inch wheels studs, and 4.10:1 gearing.

Sticking to the basics saved Pat some loot. He got his PPG Butternut Yellow, though. It was applied by Auto B Craft in Long Beach.

Wheels & Brakes
Being what it is, the SS needs only the stock (but rebuilt) disc/drum setup it came with. The skinnies are no-name 165/15s on 31/2-inch Weld Prostar wheels. Pat lays rubber with Prostars shod with 275/60R Hoosier DOT drag radials on 10-inch hoops.
