This is mainly a test to prepare us to graduate to LS7s for both V4s and the 12s

Pardon me if this has been asked already, but roughly how much does this engine weigh when fully dressed out? My Jag V12 weighs 750 and it only has a displacement of 5.3 liters (326 cu)

No joke! 
We've built several LS12s so far. One went into a suburban, and another went into 3/4 scale P-51.
We have a bunch of LS parts still laying around from those previous jobs so we're putting together some 12s for ourselves! The process gets refined each time we do it making it a little easier each time hah
We figured out how to section two stock cranks/cams and create our own firing order, and we cut out about 12 grand in crank/cam creation costs.

Got any pics of the P-51 build ??

Makes sense that it isn't much more weight...If a block weighs around 75lbs the v12 block probably weighs 100-105 since you are only adding more center area. Same with crank...only adding more 'center area'...

I can say this deal is 100% real, I went to Norway to tune the one for the P-51 Mustang. It had a Motec M800 sequential fire COP with stock Cam Sync and a external crank trigger to make it easy.
You can see more pics of the dyno and this engine on my facebook: Brian Macy
I am working on a cheaper solution for EFI with this combo, have come up with something already that will work.

There is probably only one such plane in Norway with an engine built by a guy from Seatle area. Norway is rather small with a pop of 5 million people, so unlikely to be another with exactly that spec and unknown to the people tinkering with suchlike. I am sorry to say it leaks everywhere and is considered scrap. To be replaced with another engine.
That seems like a very small issue on the first of 2 engines built. Should be easy to fix. GMS works great for sealing an oil pan or timing covers. Although the stock front/rear cover seals can be used. The head gasket would be the hardest but still not too hard. Just custom.

If it's scrap tell him to send it back, i'll gladly take it.
It's a fine piece of work.
