Nice toy!! Body looks great. Looking forward to reading about it! So are you thinking original or hybrid?
My 260z came with the 240z carbs so can't comment on how good/bad the flat tops are, but having replaced them for the Z-therapy remanufactured/reconditioned ones (on recommendation of another member), I can definitely recommend them if you choose to stick with twin SUs and your budget allows. The car is night and day better running.
Is this the ex-nun owned car we saw for sale a few months back?
