Pontiac Pavement Pounders Shootout in Virginia, Part II
Owner Bio: Shelly Brown
"I've always loved the look of the Firebird," Shelly says. After longing for a red Firebird with a white top, based upon a poster that hung on his wall, in 1985 Shelly found a red Firebird with a white "convertible" top and has owned it ever since. A racer for the last five years, one of the 45-year-old's favorite moments behind the wheel was when he took his engine builder, Paul Spotts, out for a ride after installing the Spotts Performance-built 462 engine. Shelly related that his son also shares his interest in Pontiacs and that he has made many friends in this hobby. His latest projects include a '71 LeMans and a '72 Formula 455 H.O. Shelly is pictured here on the right with his friend Bob Humbrecht, who did a lot of resto work on the car. | Strip Specs | | Year/Model: | '69 Firebird convertible | | Race Weight: | 4,220 lbs | | Curb Weight: | 3,930 lbs | | Fuel Level: | 5/8 tank | | Type of Fuel: | Sunoco 94-octane plus a couple of gallons of 104-octane race fuel | | Engine: | '72 YC-code 455 | | Cubic Inches Before/After: | 455/462 | | Built By: | Spotts Performance | | Carburetor: | BG 1025 Gold Claw, jets No. 86 square | | Spacer Plate: | 1/2-inch aluminum, open | | Intake Manifold: | Torker II | | Fuel System: | Mallory 140 pump, 1/2-in line and in tank pickup, Mallory reg. set to 7.5 psi BG filter, 5/16-in return line | | Heads: | No. 64 D-port, ported by Spotts Performance, 2.11/1.77 Ferrea stainless valves | | Flow Numbers: | 250 cfm at 0.600 lift intake at 28 in pressure | | Pistons/Rings: | Ross forged flat-top +0.030 / Hastings | | Rods: | Eagle forged steel, stock 6.625-in length | | Compression Ratio: | 10:1 | | Crankshaft: | Stock nodular iron | | Rotating Assembly Balanced: | Yes | | Camshaft: | Lunati roller, 248/248-deg at 0.050, 0.555/0.555 lift with 1.50:1 rockers, 112-deg LSA | | Installed Position: | Straight up | | Rocker Arms: | Harland Sharp roller 1.50:1 | | Ignition: | HEI, Crane Hi-6 box, PS91 coil, ACCEL 8.8mm wires, AC R45S plugs | | Total Timing: | 35 deg at 2,800 rpm | | Exhaust: | Mad Dog headers 1.75-in pri. step to 1.875 with 3.5-in collectors.
