Well i just know from all the years i had that style motor that plug gap is definitely too big, spark blow out is more "breaking up" than just cutting off, sounds like a different issue maybe the stock alt taking a shit? Who knows. I have a nice 200amp unit for you tho lolSo you think it's spark blow out? I was expecting you to say it's the stock alternator not providing enough power to the fuel pump at higher rpm.
