Here is how it all works.
You will send us your bottom end and camshaft as a core. I ask that you remove the entire top end, pistons, cylinders, head studs, etc.. Keep your engine side covers, cam chain tensioner and tension arm, charging system, chain sprocket and nut. We prefer you ship the bottom end to us on an engine stand (TC Bros makes a nice one) and in a well-protected crate/box. I can help you will the getting shipping setup. The only thing we ask is that your bottom end is not seized or damaged.

We will then ship you our Bottom End as soon as we verify your core as rebuildable. All you have to do is reinstall your top end and go. This can easily be completed in a weekend for most of you people.
If you prefer to have our bottom end in hand before shipping us your bottom end, we charge a $300 core charge which is refundable after we receive your core. We are happy to work with you as best we can.
