As some of you may know I put my cobra back to stock and sold it. Most of the parts are already gone I basically just have the long block left to part out. Started taking it apart and will continue to add to this thread. So far what I have off the motor and ready to be sold are:

Shortblock w/ roughly 400 miles on it...was still breaking it in when an intake cam gear broke while idling in my driveway and caused some piston to valve contact which you can see in the pics. It's not too bad but most likely 2 pistons will need to be replaced. It's a Boss block, Kellog double keyed stroker crank, Manley H beams and Manley 8.5:1 ceramic coated pistons. Arp main studs, rod bolts and side bolts. It also has an MMR billet rear main cover. Shortblock was $7000 new. Looking for $3500 shipped. Even if you decide to replace the Pistons for a few hundred $ you have basically a new motor for half the price.

Hey Chris, what oil pump did you have in the motor? Any chance its low mileage and for sale? Interested in a Melling or a stock pump/GT500 pump with billet gears. Thanks!

It's a tss billet gear oil pump, supposedly the best with no reported failures. It's extremely low mileage less than 400 miles on it.

So what's up with the short block? Or are you parting that out also?

Most likely parting that out also because 2 Pistons have some light damage due to some PTV contact, unless someone wants to buy it the way it is.
