Default GMC straight six



The Jimmy's were a match for the flatheads in their day. This is Saugus drag strip, the first drag strip I ever attended. My dad took me there in 1952 or '53. The track opened in 1951 and closed up in '57. This old digger ran 10.4 at 136 mph. It had the original three-port head at the time.


Another view, this time at Santa Ana, and with a body added. And still with the three-port stock head.



Looks safe enough, doesn't it?


Updated with the Wayne 12-port head, and Hilborn injectors.


Here's a photo for the ages. A single axle oepn trailer. The "tow rig" is a 1938 Chevy.

George, can you find Joe Lemleys old H/G 4-dr 63 Nova that ran those engines. If I am right you can bore them .060 and it makes the engine 311 cubic inches. Dick Humbert that drove Stepps first P/S car built one. It ran 11.50's back in 74 and was a street car.

The roll bar went up to the driver's shoulders, what more do you want?

Them GMC 6's are still pretty bad, just watch Self Racing's car go down the track a time or two! Or that turbo Nova Wagon with the Trailblazer engine.

Well, it was a concern but just one of many concerns. Look at the "slicks". In those days, the slicks were all re-caps. Actual drag race tires did not exist back then. With the exception of the Hilborn injection, there are no "aftermarket" or actual "race car" parts on the car.

When you look at those old pics, the inspection bills don't seem so bad nowadays.

A broken shoulder can be very painfull therefore they were quite concerned about having the roll bar up high enough to protect the shoulders from damage!
