Quick Inspection:
'63 Pontiac Tempest LeMans
Rob Freyvogel - Butler, PA
POWERTRAIN
Engine: In 1963 the Tempest LeMans was powered by a 326ci Pontiac V-8. The engine in the car now may be painted blue, but it's no Pontiac. That's a 427 big-block Chevy with a 0.030-inch overbore and Brodix aluminum heads. The build is on the conservative side to accommodate the pair of Holset turbos stashed away under the rear of the car. The homemade 4-2-1 headers use 2-inch primary tubes and 3-inch collectors, while the throttle body is a 1,600-cfm airdoor from Electromotive.
Power: The car made 875 hp at the rear wheels on a chassis dyno, but that was early on the development curve. Based on the car's e.t. and trap speed, Rob now estimates that he has over 1,100 hp available.
Transmission: Rob axed the Tempest's original drivetrain configuration, an odd setup that employed a rear-drive transaxle and enclosed driveshaft. He opted instead for a GM Turbo 400 with a transbrake and electronically actuated valvebody.
Rearend: Rob says he learned about the virtues of the '57-'64 Olds-Pontiac rear axle reading HOT ROD. His uses a Strange 35-spline spool and axles with a 3.08 ring-and-pinion.
CHASSIS
Frame: Except for a pair of fabricated subframe connectors, the Tempest's unitbody structure is stock and original.
Suspension: While the front suspension is stock, the rear now employs
coilover spring/shock assemblies and a pair of Chassis Engineering ladder bars.
Brakes: The rotors and calipers are Wilwood Super Lights, while the master cylinder and power booster are from an '86 Buick Grand National-no engine vacuum required.
Wheels: The steel rear wheels- 9x15s using the GM big-car 5x5 bolt pattern-were custom-built by Stockton Wheel Service in Stockton, California. The front steelies are 14-inch GM stockers, and Pontiac dog-dish hubcaps are installed on all four corners.
Tires: Hoosier 28.5x10.5 Quick Times are on the rear, with Goodyear radials on the front.
STYLE
Body: The GM Y-body platform, used by the Buick, Olds, and Pontiac compacts from 1961 to 1963, was a bit of a strange ranger, sharing some architecture with the Corvair. But the lines were pretty clean, especially on Pontiac's Sport Coupe version for '63. Rob didn't change a thing on his.
Paint: Rob believes his LeMans was repainted sometime in the mid-'80s in its original factory metallic red. That's the same paint it wears today.
Interior: Except for a set of Auto Meter gauges artfully spliced into the dash, the cabin is pretty much all stock, with factory bucket seats resplendent in early-'60s GM red vinyl.
