Dana, mine is sitting on my Cobra broken, it runs, but the frame is broken
and the fan spins very slowly. Gotta fix real soon.
I got a great deal from Tousley Ford, saved me a bundle. Ken

I put maybe 1600 miles on mine this year and I never race it so hard for me to say
I did shoot a plug out of my passenger side head, so I'm down till the spring......
That happened to me too. The #7 cylinder. Scared the SHIT out of me! Blew the scoop/snorkel off the hood and everything.
A helicoil will cure the issue.
