The Jaguar engine in my ECTA car has what was the latest thinking in water jacket design back about 2000. Since it has overhead cams, there is no necessity for a cam tunnel. The water pump fits into the front of the block and the water jackets only extend down about two inches around the tops of the cylinders. The block is aluminum with ferrous sleeves cast in place.
I'm doing a re-design of some features of the FE block---specifically in order to optimize for the SOHC lay-out---both for cooling and strengthening.
Your comments are solicited in regard to copying the most obvious cooling features of the AJ (Jag) block.

So, you are thinking about moving the water pump? Or are you just concerned about the relatively small water jackets? My SOHC has the block filled up to the water pump holes. Water stays nice and cool, but the oil gets rather hot...

but the oil gets rather hot...
Do you run a cooler for that?

I didn't last year, but I'm thinking about adding one this year. Need to do some more in-traffic driving to find out...

Did you go to dry-sump on that cammer, Jay? The way I'm planning now, I'll be using a DS with all the necessities to cool the oil. And probably using a remote electric water pump.
What I envision is very akin to a partial block fill but as part of the casting and not as a foreign substance put in afterward.

Yes, it has a 6 stage Peterson dry sump system, uses about 11 quarts of oil. The oil still gets pretty hot, although I've run without a cooler so far. Not unusual to see 225-230 going down the road, while the water temp is at 170. I was a little surprised by that, figured that with the oil volume and the separate tank the oil would stay pretty cool, but it doesn't.

Will that be iron or aluminum? If iron, that thing would be HEAVY with the jackets full of casting.

No, we'll be going Aluminum.
