does your engine look like this? is this a quad 4
can anyone make out the casting numbers
Holy shit, dry sump and all.
What a wickedly rare motor. The valve cover doesn't look like quad 4.
No, that's a Super Duty, just like it says on the valve cover. The Super Duty engine is used a lot in circle track racing, and also powered the 1984 Indy Fiero Pace Car. Much older design then a Quad4, but a kick ass engine. They cost some cash.
Edit- The 2.5 that the next poster's quote references is none other then the Iron Duke, which has been underpowering all sorts of 80's GM cars up to this day. Polishing a turd can be done after all.
Little tidbits I found about this mill:
"In order to enhance our four cylinder image and to fill a void for four cylinder race engines in the NASCAR, SCCA, IMSA and NHRA racing series, Pontiac has developed a new line of high performance "off hi-hway" parts for the Pontiac built 2.5 liter (151 C.I.D.) L-4 engine".
"We are pleased to provide the attached listing of part numbers and specifications for these Pontiac performance parts which are available through GMPD for immediate shipment. Please pass this information on to your Service and Parts Managers".
PONTIAC 2.5 SUPER DUTY DEBUTS AT DAYTONAThe Pontiac 2.5 liter Super Duty engine premiered February 18 at the Daytona International Speedway, powering three GM J-cars in the NASCAR Darlington Dash Sedan Series. a l80-lap 450-mile race.The fastest qualifying time and the pole position was won by Mike Waltrip, driving a J-body (a Pontiac 2000 for the Atlanta race). Waltrip is the brother of Darrell Waltrip, the 1981-1982 NASCAR Grand National Champion
Waltrip's car was powered by a stroked 2.7 liter Super Duty Pontiac engine with a 7,200 r.p.m. redline and a compression ratio of 12.5 to 1 (carbureted version), and horsepower was estimated in excess of 250.
