I ask this question because i can get 2 new blaster coils, 2 new 6al boxes,and 2 used 6al boxes for spares for $300.00(im getting them through a friend of mine who has a sponsorship with MOPAR)....the used boxes only have been used on the dyno, and dont have any real run time on them....Thought for that price i could cook a few boxes and still come out ahead.....

heres an idea.buy two marine box,s and use the auto stuff as spares if the harness are the same.i have 8years on a marine msd box and two boats later,and three motors it still works fine.but i always carry a spare and a coil.better be safe than sorry.

there is no way I would pass that deal up. Then you would have two spare boxes, no worries!!
