Replacement MS main board. Takes an MS3 processor. Has hardware for 8 spark outputs, 8 injector outputs, four cam VVT, dual map sensors, six wheel speed inputs, real time clock, knock sensor interface, spots for two SLC DIY wideband drivers, on board CAN I/O expander with 16 analog inputs and 8 digital inputs, and waterproof automotive grade connectors. There's a bunch of other stuff in there as well. It's a long list.

Not available, not for sale, so don't ask.

Plus those white plastic electrical connections aren't going to work anyhow.

What's better than a B8444S?

Two B8444S's.



This second motor is most definitely trashed to some extent. Looks like the previous owner drove it with a bad balance shaft bearing and popped the timing chain. Not sure how badly the top end is damaged, but we'll be tearing it down shortly. Should make for a great mock-up engine and extra parts source. It also came with a few boxes of crap and a complete transmission (woo!).

Got it fully torn down. Block, crank, rods, and pistons look pretty good. Other than that, it's fairly wasted.

The failure mode was fairly obvious once we got the balance shaft out. Rear balance shaft bearing seized up and fell apart, leading to failure of the front balance shaft bearing. Once the shaft was unable to spin, the sprocket sheared off and the timing chain suffered... shall we say "spontaneous catastrophic disassembly". The chain cracked the oil pump housing and broke one of the tensioners. Also found some bent valves.











Haven't looked too closely at anything yet, but first impressions of the design are good. The castings look to be very high quality and the designers have clearly gone to some lengths in order to make a compact and light weight engine.

After seeing the balance shaft failure, are you going to try and eliminate that?

Yes, we're going to eliminate the failure by installing a new bearing. The shaft is staying. I don't see a good reason to remove it.

Scotty, the balance shaft failure was caused by water intrusion into the V of the engine. At the rear, the bearing is a sealed unit, and the water would collect and cause the bearing to rust and fail. There is a bulletin from Volvo on drilling a drain hole for the water so that it can no longer fill up the valley and damage the bearing.

Awesome that you got 2, Buchkas! Gonna be epic when you're done for sure. Hope I'm still alive to witness it...

No, water from washing the engine, etc. It would have to be quite a bit of water, but it just pooled and had nowhere to go.

Thanks, Rob! We're pre-emptively adding wheelchair access to the car so we can finally drive it when we're all old and decrepit.

Dropped the engine in the bay last night. It's within a few millimeters of the intended position. Looks like the cowl area is going to need some modifying to fit the intake manifold. Firewall will also come back a bit to make room for the coolant manifold that bolts to the back of the heads.



The front two cylinders line up with the front axle centerline. Not quite mid engine. :(



This pic shows how the exhaust ports are offset from the ports. The front one is especially bad. "Fixing" it would be a pretty ****ty task that neither of us is interested in doing. Hopefully we can get a head on a flow bench to see how it matches the other ports.

That thing is extremely similar to a Cadillac Northstar.

Not much 240 left. You should just rename the car.

Just to the left of the 'front' exhaust port in the last pic above are two bosses/holes where something attached. Was making room for that accessory the reason they moved that port rearward? (talking about the 2 larger holes, to the 2 smaller over/under ones....) Both heads configured similarly?

Yeah, it's to make room for the water pump and alternator. You can see the water pump here:
