I payed an extra $1300.00 for nothing more than chrome valve covers and a chrome oil pan. You might ask how could they get away with that?....how many buyers are going to tear apart a new engine to see what's inside or have the knowledge of dynamometers for testing output? Tested output on my engine was off by over 100HP from the horsepower they said it would produce. http://www.yellowbot.com/five-star-engine-cylinder-head-exchange-inc-glendale-az.html Sold me a bad engine! They are a Rip Off so beware. Do some research on them; see rip off report.com and craigslist ads - I am not the only one they ripped off. BEWARE! http://www.yellowbot.com/five-star-engine-cylinder-head-exchange-inc-glendale-az.html Please consider avoiding fivestarengines. I paid in full, yet they never sent my engine, having to jump through major hoops just to make things right. Another guy paid $7000 for a 427 that blew in 700 miles. Save your money and buy elsehwhere. You wont be sorry Please notice that the person above recomending fivestar, and posting 5 stars, is the owner of fivestar engines, Chris smith. He is not to be trusted.
