MRL Performance 340, WOW!

Nowhere near the power of today's engines, but in the early 70's, this 340 below went 12.70's shifting at 7k on the street with 5.13 gears, and I can tell you it's one of the most fun rides I was ever in.............
Now that is nice , and fast . 5.13 gears what were you revving when you crossed the line ? 12.7 is pretty fast , 7 k must have been a well built 340 .
