best educated guess on HP

You guys are crazy. The eagle heads may be good for 20 over the stock 5.7 heads. That cam is not enough to take advantage of the heads......420-430 flywheel at best. Its a poorly matched combo too. That 273 cam isn't good for much of anything except a smooth idle. It bleeds off too much cylinder pressure down low and cars that run it are turds until 3500 rpm. Maybe 340 wheel horsepower on a dynojet assuming the tuning is solid
