good info! Yes I see where they have changed the rules for the exhaust. I will call schoenfeld & see I can get that header with a mopar flange. I'm wondering if I should get the kit instead of the finished header & mock it up & see if it will fit my very tight chassis as is or it needs cutting/trimming as things are so tight in a early A body tho I ain't competent in that area (header fabbing). yes a header with a 2&1/4 outlet will be night & day ahead of a log manifold with a 2" outlet. Actually I have a 9" furd rear (not sure what ratio) & not sure what a floater is, that's been sitting & would need to be checked out/gone thru. the 7&1/4 still has 3.73's in it right now which'd be 5:41 in 2nd. I'm thinking I can mod the valve body so it wont shift into 3rd??? (also not my area). Hey stay in touch. RR
