I will speak for my 68 L79. Which has had port work done to both the heads and intake, built with 11:1 pistons 30 over and a fully balanced rotating assembly. It sure does have a different powerband than I have ever driven. I will be puting the aftermarket tach in the dash this winter so I can see what Rpm this actually does this; I am going to say around 4-5K once the car gets rolling the power just keeps coming on. Very hard to explain! Looking forward to some more test and tunning in the spring. Maybe even get it to the track. I could see why these are known sleepers back in the day!
