I had that exact same crate motor in my old stang and it would put down 285 on the dyno all day long. It may not the best value for the horsepower but I tell you it is reliable as you can get. I would take it to the strip every week and out on saturday nights for 2 years straight, put over 40,000 miles on it this way and never broke a thing on the motor. I then put a supercharger on it and ran it another 1.5 years and put another 20,000 on it. Then sold it to my friend 4 years ago who still has it and has put 80,000 miles on it and has never been in the shop for motor repairs and still puts down almost 400 to the wheels with the supercharger. Can't get any better than that for the money!Hickfied said:Real world dynos from friends... Just look it up on the internet... 345 - driveline lose + over rating = no where near advertised hp.
