I guess all those high speed runs did your motor in?
Yes they worn the motor out... NO they didnt cause the scratch
Here you can see the scratch at 3 gallons when I found it during the rebuild
Now here is the same scratch with 6 gallons thru it, notice the wear and the scratch is more noticable
Its really really hard to tell if it truly hampered my performance, why because I was still able to reach 59 mph. Im sure there was some power loss but it had to have been minimal at best. The only way to truly know is to have a fresh motor built and try again. Even of the motor was repinched it would seriously yield me another mph or two, but the scratch would still be there.
