We are restoring two 1968 Datsun 510 2 door cars and a 1970 521 pickup.

The pickup is just about ready for the road, the two cars are in various states of dissasembly.

I want to really modify both cars one with more stealth, one with obvious mods.
I have lots of parts to make the cars original, it tis the mechanical approach that is the interesting part.

I want to stick to old school engines, but max out the displacement, with the stroke adjusted differently for the two cars, torque vs. horspower.
