Guest Posted May 14, 2003 Share Posted May 14, 2003 I have a 60 Impala 2 dr ht. 348 tri power, I am haveing some jetting problems. I need to know what size jets where in the 2 brl rochesters from factory? the 348 is bored .30 over with the high compression pistons and special cam. Once I find out what size the factory suggests should I increase the size because of the bore or leave it? Link to comment Share on other sites More sharing options...
