i got my new motor from car-quest auto parts, and i know that these are remanufactured motor's basically rebuilt motors, ive heard that the head's and cam are probably different, and thats why my car doesent seem to run as well as it did before, but also ive only gotten to put like 500 miles on the motor and my timing was off a little and my plug wires were'nt clamped on right. If anyone know's anything about these motor's and could tell me anything i would appreciate it Thanks -Don

 

If they're anything like the GM goodwrench and other stock replacment motors you're probably dealing with a whole lot less compression than before.
