Pontiac GTO Tri-Power Three Deuces Tee — Black

Black oversized tee. A plan-view drawing sheet of the 389 with the air cleaners off: three Rochester 2GC two-barrels. The centre primary, the only carb with choke and idle circuits, is in red, while the front and rear carbs open progressively at larger throttle. On the 1964 GTO, Tri-Power meant 348 hp and 428 lb-ft.

Part of the American Muscle collection by Boost Cars.

The print

DTF transfer with a dense ink layer: a large back print 26 cm wide and 37 cm tall, plus a small hit centred on the chest, 10 cm wide. Colours stay put — no cracking, no fading in the wash.

Fabric and fit

Heavyweight cotton that takes daily wear, boxy oversized cut with dropped shoulders and a ribbed collar that keeps its shape after washing.

Sizes

Available in S to XXL.

Care

Wash inside out in cold water; never iron directly on the print.
