now you got me thinking since the Neon DOHC motor is a cousin of the T3 motor in Spirit or Daytona R/T, man! i miss my Spirit R/T hey i do have access to Neon motors don't know what type but will find out soon as far as the distributor just run it of the cam like modified T3's so you can still use the stock or modified T2 computer.
p.s. are you sure about the pass. mount?
