lol Nope. My motor is complete now. Just waiting on install.

 

[CrankThis!]

Is this the same motor in that runs 11.6's in a Jeep. LOL That's a hell of a deal , let alone those mains run for about 500-750. Now through some Gen. 2 Wet Flows on that sucker and you have a hell of a combination.

wait is this a used motor or a new motor? I am confused why did they have to warrenty your motor?

 

[sgtstanko]

Why??

wait is this a used motor or a new motor? I am confused why did they have to warrenty your motor?

I have removed the heads and oil pan on several occassions to see how the engine is wearing. I discovered a problem that was not addressed at the begining of the installation. The K1 crank has a radius on the end. Arrington includes a Bulletin that tells you to chamfer the cam/oil pump gear. If you do not it will bind the oil pump. The dummies(to remain nameless) that received my engine threw out that bulletin. Consequently the oil pump sent debris into the motor, and I contacted Arrington to inform them of the accelerated wear. They asked for the engine back for forensic examination. I agreed to purchase another one while they examined it.

They recently contacted me that they will warranty the the engine....PHEW, how many engine builders do that??

Anyway the engine is waiting on the final parts (new pistons) and at their factory and will ship in about a week. I dont need two engines, so I am selling it. This engine has the Pro-Gram billet main caps which are an extra $700 feature at no extra charge.

Fitted with the Mondello Stage2 or 3 heads and the Mondello Stage3 cam, this engine will produce well over 630-650hp naturally aspirated at the crank.


Anyway, this Arrington K1 engine had 10,000miles before I pulled. In essence it is a brand new engine with all NEW PARTS and will still carry the Arrington warranty.


Here is what it looks like......notice the radius at the end of the crank where the cam gear sets.
