King Krate anyone?
i had an engine built by muscle motors, it took 5 weeks longer than they said, dyno date was early may could not pick up the engine until the end of june. ran it for five or six race then the rocker broke, popped the valve lock, dumped the valve and destroyed the head and cylinder. they said that was to bad, they would build a new engine for me. had $18,000 in the first one. had a local shop do the machine work and i talked with a few guys that assemble there own engines, read a few books, purchased a few extra tools. i haven't had a complaint. sold that engine in my race car and still runs strong. i rather build my own.
