'The Rod Shop' 1971 Dodge Colt Station Wagon
I would like to see more detail on the G-W heads.
Don't see anything with detail.
There's a article in '69 Motor Trend showing Pete Hutchison building the USAC 318 stock block indy motor at Keith Blacks shop. They were testing flat 180 deg cranks.
The G-W heads are just the next iteration of that Mopar stock block indy motor project. They added about 40 HP over the traditional designed irons.
I thought the G-W Mopar head is just designed around the G-W Ford. Just adapted to the Mopar block
These two pictures are from the Motor Trend article I believe.
The G-W headed small block tried to make the 69 indy race with Art Pollard driving, but they blew all the motors. That was in a Gehardt chassis. The the first set of heads were reportedly delivered directly to track at Indy just two days after the STP race cars arrived! They moved Pollard to a car with an Offy motor for better relibility.
There are press pictures of a #20 STP "Super Wedge" car with Plymouth lettering and motor. That car has a large wide wedged front nose. The motor with the G-W heads did not fit that chassis. The whole chassis was shelved, never to be seen again. Although there were lot of press photo released from Plymouth on the car.
Later in the year, the G-W headed motor was in a Gerhardt chassis and #57 and won at Dover Downs oval USAC race. That car looks like a long wedged stick. I believe that car is the car in the Speedway Motors parts company museum in Omaha Nebraska. Car ran Riverside.
One of those chassis' were tested with a modified 727 automatic transmission in it. There's an article in a 1969 Hot Rod on that. IIRC, one other issue/mag also.
