We got an 540ci Chevy motor from them took about 2 months but we where not in a hurry.This was are first time dealing with them.We had no problems with phone calls or anything like that.When the motor was ready we made the drive to there place.Very nice and clean.The guys we talk to there where all nice.Did not have a problem with any of them.They had the motor on the Dyno ready to go.Made about 4 pulls on the Dyno and it made 898hp at 7000rpm..I am glad to say we have put over 125 runs on the motor and the only thing we have done is change the oil and Check Valve lash and switch it over to Alcohol..The motor has ran a best of a 5.28 at 130 mph in the 1/8 in a 2465 lbs car & driver.We are please with what we got and has been trouble free..
