How valuable would the original drives and engines be worth off of a magnum? I believe the drives are the volvos and the stock small blocks and transmissions.

If they are Volvo E-drives, they are downright dangerous to be near. Contact me and I'll remove them so nobody gets hurt.

Not quite sure what they are yet. Going to look at this Magnum soon and it is all stock. I would like to go with a single BBC instead of the twin small blocks.

please explain??????

They are a quick way to add 5-10 mph to an older volvo outdrive equipped boat.
Finding them in good working order is like trying to find hen's teeth.
I'd add a picture, but can't yet.

ok so it is similar to a blackhawk.

What makes them different?

With their depth and shape, they are way more efficiant through the water. They also came with a few ratios, as low as 1.3ish. With no other changes, they can add a bunch off mph's. The downside is they are old and hard to find and harder to get parts for.
