ive been getting my information about the 727 swap ,
i learned from the threads about a 518 w/ overdrive instead.
the sierra grove kit (975$)will allow for the 518 as well as the 727 with a crossmenber snip and a couple of hole enlargements ,I can use my starter and flywheel BUT i have a 6v pos ground automobile ;
there is a 3 pin connector off the older noncomputer 518 .the two outer pins are ground but the center pin requires a hot wire to run 2 solenoids; one for the overdrive and one for the torque converter lock out;
in various places I read that the solenoid actually runs off 8 volts and some places say 12 is actually too much .So my big question is will it function on 6 v ?
Ive been resisting going to 12v for some perverse reason ,have been happy with a power gen alternator,pertronix 6v point replacement and big napa 6v forklift battery ,
