Why does my horsepower drop off so fast?
This has been bothering me for months, looking at my dyno chart my HP drops off like a rock. Compared to other LT1's, their HP doesn't drop off even close to as fast as mine.

Looks normal to me. Adding a cam with higher duration will shift the HP up and not fall off like the stock cam does.
You also have to keep in mind that most curves that you see with the stock cam only go up to 5700 rpm, and you spin up to 6100. You will see the dropoff on your dyno chart, but you don't see it if you only spin up to the stock redline.
Also, your 1.6RR's make the curve more peaky.
