Horsepower Estimate?

Thanks for the responses. A lot of the information I collected was 2nd hand. I have written a letter to the guy that built it. Hoping he responds with better info. I was mainly hoping it would be at least somewhere near 70-71 stock numbers. It does run pretty strong for my needs.
If you're happy with, don't worry about the numbers. That'll drive you insane. Just drive it and have fun.
