It tickles me how everyone is obsessed with HP numbers. He also can't tell you cause he doesn't know. Your brand new rebuilt engine is going to make different horsepower than one that has 100,000, and they'll both be different from one with 200,000 not to mention elevation, quality of fuel, and everything in between. I always loved it when someone came in the speed shop and wanted to know how much horsepower we could build into their engine...I always said "A top fueler can make a couple thousand, would you like those options?" Would have been no problem to build them one, my boss had built MANY over the years, so if they'd have had the cash, we could have built it!
