Testing the 273 on the dyno....

The Detroit guys said the 340 was more like 375HP, That was from a Hagerty special on a legendary black 340 that roamed the streets of Detroit, street raced by an off duty cop. Perhaps wishful thinking.....
Yeah I recall it revs a little higher than the 318 i wonder what the 318 would do at 6000 rpm although I believe the 318 drops off power wise by that point.
