Re: 393 stroker rwhp
To Dennis' point, the power numbers in many magazine builds are often suspect. There is debate over which dyno provides the most useful information, but both engine and chassis dynos can be manipulated.
Also, the "big-time" engine builders typically have numerous performance "secrets" they have learned over the years to get every ounce of power out of an engine that the typical engine builder doesn't know or doesn't bother with.
That being said, I wouldn't make the assumption that because a similar engine in a magazine article with a smaller cam made "x" power that yours will make more. I'm guilty of making that same mistake!
I've made several trips to the chassis dyno, gone through a process of changes and adjustments, and never quite reached the "easy 450 RWHP" I thought it would make on my first trip to the dyno.
I wish you well and hope that you do make the numbers you want. When is it going to the dyno?
