Just curious,

I Have a 1974 260z, would this year model have a baffled fuel tank?

Not unless you your 260 came with FI....

Thats bizarre,

My brother has a 1971 Datsun 1600 (510) and hes got a baffled factory tank,

He had a sweet way to mount an internal EFI/Turbo pump by securing it to the baffles, would have been sweet to go with the same setup as it would be inside the tank

Only if you ask it a question it can't answer. (sorry, couldn't resist--j/k)
