The Pure Stock Muscle Car Drag Race (PSMCDR) organization is announcing the inclusion of select 1975 to 1979 Pontiacs allowed to participate in the best “Pure Stock Drag Race” in America. Due to many folks asking if they could participate and race their ’75 – ’79 performance Pontiacs over the years, we have decided to allow performance focused Pontiacs to the event (this year is September 15, 16, & 17).
The following list of cars may participate:
Year Model Engine Rated Horsepower
1975-1976 LeMans/GP 400/455 185/200
1977 LeMans/GP 400 185
1977 Can Am 400 200
1975-1979 Formula 400/455 185-220 403 when equipped (78-79)
1975-1979 Trans Am 400/455 185-220 403 when equipped (78-79)
Please refer to the PSMCDR web site for the rules, but in a nut shell, you can run a 2-1/2” mandrel bent exhaust system with the muffler(s) in their factory position without catalytic convertors; any gear ratio; stock or close to stock cam (16” vacuum at 1000 rpm); radial tires in 60 series max; stock torque converters (12” TH350/13” TH400); factory transmissions, interiors, bodies, paint color(s), wheels, etc.. Engines can run 1.5 points higher compression (7.6=9.1 max/8.0=9.5 max/8.2=9.7 max); stock or very close to stock cam specs (16” vacuum at 1000 rpm); factory carb (and type for year); heads/intake/exhaust unmodified; max .070” overbore/ .015” stroke increase (from previous machine work) allowed; all belts to operate power steering and alternator (A/C belt can be removed).
We will P&G (displacement), Whistle (compression), and check vacuum on cars that run 13.50 or quicker to inure compliance to the rules.
