on a 99? i have no clue... imma pushrod kinda guy

 

Chad I went with colder plugs and retarded timing on a 75. I got really bad break up past 4,xxx with stock plugs. Might as well do it because once you spray, you be going up in the shots very quick Put the kit on and take it to RaceRelated. Make 2 or 3 pulls there for the air fuel. Have James adjust the timing. It will be cheap too
