Jenko's crackerbox

After going to a circuit racing event at the local boat club I thought that I needed to build a faster lighter boat so I have ordered a set of crackerbox plans :D

Was thinking of 383 holden v8 (stroked 304 ci)
But the one that is getting me thinking is the toyota 1GZFE v12 it has a good bore stroke ratio B 3.2'' S 3.18'' ,4 valves per cyl, variable valve timing performance parts readily available 390ftlbs torque @4000rpm :P

Pete, I had no idea Toyota made a V12... are the engines available outside of Japan?

I work in a large toyota dealership in CA. I spoke to our parts manager this morning, and he told me that he can't get parts for items only sold in Japan.
Getting parts for that engine might be a problem if you go that route.
