That was a typo on my part, sorry. I had a few drinks when I made that post. I meant 900+rwhp, which is close to the 1100 or so claimed fly wheel horsepower that ford claimed. I don't know where you guys are getting your info on the ford sportsman block, but I'm fairly certain you guys are putting more belief into what it can hold that it actually can... do some searches and see for yourself. Ford list it at 600fwhp, which is a LOT less than 700RWHP. Suffice it to say though that the A4 block will prove to be a sound foundation for whatever Charlie decides to throws at it and it will be the last thing he has to worry about breaking when he gets it all together. I can't wait to see what he assembles for his kick ass car.
