BIG question.........are you installing an Alterkation "K" member??
Per Summits listing, the D454's are for early 'A' with Alterkation "K" member; the D450's headers are the D-Dart headers.....BIG difference between the 2!
Don't know a thing about the D454's; have a set of the D-Dart 450's, I like them.
I better get my $hit together before I order headers for this car. Need to find the pn for a 1965 273/904 Valiant. You guys have saved me a ton of grief! I'm totally new to the A bodys and my ignorance is showing! Thanks again!
