    Tri-Y header design?

    Hi Guys,
    for my car id like a good set of headers that are street oriented and don't cost much ground clearance.
    The frame horns are still in use so 4-1 long tube headers would hang really low.
    Also i notice that most headers are for a 350+ engine and have reasonably large primary tube.
    I'm looking for more street oriented manners.
    Using the various calculators i keep finding that the primaries should be less than 1.5" OD.
    Are there headers that would fit the bill? Peak torque at 3500 and usable for a 283.

    Seems to me that you might want to look at using stock cast iron manifolds or a 3/4 length header for your situation. I don't know if I've ever seen headers with smaller than 1 5/8" tubes. Something like these should work...

    Here's some inexpensive stainless ones. Check the details on any of these before buying.

    Thought about 2.5 outlet rams horn manifolds, Speedway has a good price on them.

    Currently I have the 2 inch rams horn manifolds installed.
    The suggested 3/4 length headers look nice, but the Trickflow cylinder heads are angle plug.
    That does complicate it a bit. ☺️
    Diy would also be a good solution.
