    Default Bassett water line AN size

    Does any one know what the Female and Male AN size is on Bassett headers going into the header? Small 4 lines.

    Are you looking for the size of the threads in the headers themselves or the lines going to the headers.

    Yes, pretty sure the bungs are 1/8 npt. The adapter for the hard lines are -8. What I'm confused about is what is the op asking. Are you trying to make your own lines or what? Do you have the lines and need the adapters at the tubes or what are you trying to accomplish?

    I have made a 455 to 454 conversion. I bought a set of used headers with no lines. Im wanting to use my OLDS water lines in lieu of buying a new pair!!! Just trying to save a little money. Ive been told that the OLDS lines will work and WONT. I was going ot get some hight temp line and jsut add on to the olds and give my self plenty of room to work with. Any suggestions are greatly appreciated.

    I don't think the small lines going into the header tubes are 1/8" NPT, seems there is a flare on them?

    The small lines are not, the bungs are. There is a brass npt to flared adapter screwed into the header. They only list header fittings, none are brand specific so other than the hard lines lining up or reaching, I wouldn't see why they would not work...

    Bungs in headers are fm 1/8NPT. Fittings are 1/8NPT (male) to -4AN (male). I have them in brass just like stock ones that from bassett. Spacing will be different Chevy vs Olds. Ford/Chevy pretty close. Olds/Chevy not so much. Olds seimese exhaust ports in center.

    Got it. Thanks.

    It has been a while since I have pulled the little fitting out of the tubes.
