That is not my junk. I posted this to illustrate how a relatively small N/A c.i.d. can produce near 400 to the tires. The limited cam lift (.499") is due to the nature of the class the car competed in at the time. The duration is pretty healthy for the amount of cubes, however, the amount of rpm generated with P/S cars now requires just a little more duration on the intake/exhaust lobe
