I won’t leave you guys hanging. Here are some details about the motor:

Originaly a 1987 jag [motor], but most of the motor has been modified. Parts are scarce so I had to make most of them, which included coming up with my own cam profiles. With the assistance of crane cams I am the first person to use a dual pattern cam with the Jag H.E. v12, because of camshaft changes it caused me to have to build my own timing chain setup,idler pulleys, which I made externally adjustable.
Jag rods are a heavy 975 grams each, so I had the crank ground to use H-Beam 351W ford rods, total saving was 11 pounds off the rotating assembly. Actually I could of used a lighter rod, H beam rods are good for 750hp, but thats for a V8 (94hp per rod) in a V12 the same rods means I could run 1128hp which this motor will never see. From here I used 1.5mm Honda rings, with custom BRC pistons for nitrous. Compression came out to 13.5:1. Heads were completely reworked and ported. Aluminum flywheel and custom bell housing let me mount a 2003 ford mustang 5 speed transmission and clutch. So far I have over 1 year in the making of the motor alone and probably spent more money then the car will ever be worth but I guess thats what a hobby is for.

Dude gets my respect for sure.
