Was able to check this out first hand yesterday and I can say that this little Datsun is shaping up quite nicely. Very inspirational and I can wait until we have an official above freezing day to wrench on my TE72. The Ratsun folks are going to go bananas with your new setup and tweaks! Toyota to the core but a def soft spot for the 510 :)
The 3tc is a beast of an engine. Not a bizarre choice if you are a true old school Toyota fan and probably one of the most sought after, reliable and rock solid poweplants Japan has produced. It's a true baby Hemi :)
