I figured it would be in that area.

I don't have any personal experience with the Avenger folks.

Have you had a dyno on your current combination? What is the combo exactly? Cam, carb, tranny, gear etc.

Any time slips?

Personally, I like to look at bang for the buck and what it is I want to achieve.

I wouldn't out of hand dispute their claim on the hp increase......but much would depend on your current output.
