I'm sorry......I am asking $5,500 for the short block. It is currently at Arringtons in West Virginia.

I could include a set of heads at my cost if interested or you could run any other combination.

So what happened to your first 426 that Arrington is warrantying it ?

And would this be your old engine repaired by them ?

The damage was not their fault.......all K1 cranks no matter who sells them have a radius on the crank right where the timing/oil gear sets up against. Arrington sends a warning Bulletin with all their shortblocks that the gear needs to have a 45 chamfer BEFORE installing. Otherwise that gear does not set flush and binds the oil pump. It results in the pump gears grinding. This results in small particles going through the engine. I caught this because of the constant R&D I have done testing the Mondello heads. I told them what I saw and they wanted the engine back. I bought another one because i couldnt have the Jeep down. It is my daily driver.

They stepped up and are building me a new engine. I am reusing my crank, rods and ProGram billet main caps.

In essence the engine is new and will still carry a warranty.

Joe and Comp came up with it

For advertising purposes it is a 222/224 572/560 on a 116LSA

I'm heading over to see Bob@SVS for final tuning next week. This last Thursday at Irwindale (1/8 mile track) with installing the Mondello cam it picked up about a 1/10 and 1.5-2mph with just the cam swap replacing the stout HHP Stage 3 cam.
