1969 Plymouth Barracuda

The dyno sheet says "440 six pak" in the upper left hand corner, maybe wrong dyno sheet.

No, correct dyno sheet. Just the engine test description was not changed on the computer, but that is the dyno sheet of my engine. That is a picture of the hard copy we printed out after the final test run. I also have videos from 3 pulls at the dyno test day.
That would be a very weak 440 six pak :)
