They're excellent motors. My mom has one bro. They have low compression and iron sleeves I believe, as well as excellent flowing heads. Good for N/A but a great F/I motor.I'm actually pretty impressed by those f22a4 motors. I'm sure someone's pointed it out before but I believe someone pushed like 400+ outta this motor n/a. shockingly enough.
