Tri-Y headers were designed for the 1965-66 Shelby GT350 with a 289 HiPo, 4-speed and manual steering.

-Includes mounting hardware, gaskets, and 2-1/2" collectors.

-Will NOT work with 351W due to taller engine height & width.
-Will not work with GT40-P cylinder heads.
-Only fits 10 or 10.5" clutch, use of 68-up bellhousing means LH side hammering.
-1969-1970 models require additional clearancing for steering box.

-Some 64-65 V8 Engine Mounts sit the engine approximately 1/4” lower than the  66 and up mounts. Although unlikely, it may be required to shim your engine up  especially if mounts are older and have partially collapsed to gain more shock tower clearance. This can be done simply with some washers.
