1st time ever owning a motor with nos. it is a 468 bbc 10.5 to 1 motor,steel oval port heads, tr w 2-660 c/s with 125 nos on each.
if more info is needed for answer let me know!
i have no knowledge in this matter and have heard that u have to run a smaller plug gap, because the nos will blow out the spark.
i'm no motor head so keep it simple. i just want to do this right to lessen the chances for a big boom !
