Quote: Has anyone used the PN P5153816AB 6.1 block? I assume this is the same as the production 6.1 engines are equipped. Is there much finish machining needed to make it usable? The price looks pretty low for a ready to run block. Anyone know if they are even available? Thanks
I have used it. It is a mass produced OE factory stock bare block with caps. If you're building a stock engine, there isn't any finish machining required. If building something else, you'll want to machine to whatever you need. Availability is zero at this time, because the plant has switched over to 6.4L engines/6.1s are not available in production Chrysler vehicles anymore.
There is a chance they MIGHT become available again at some point, but it will require a very expensive tooling changeover at the plant, and it may or may not happen. All a guy can do is keep an eye on it and hope for the best.
