GMC “Twin Six” V12 hot rod

What a sweet idea! Definitively dont see many (any?) hot rod builds that use a Twin Six.

GMC produced a large gasoline V12 from 1960 to 1965 for trucks It was basically GMC's large-capacity truck 351 V6, doubled, with four rocker covers and four exhaust manifolds. Fifty-six major parts are interchangeable between the Twin-Six and all other GMC V6 engines to provide greater parts availability and standardization. It has 702 cu in (11.50 L), and while power was not too impressive at 250 hp (190 kW) for such a big engine, torque was 585 lb·ft (793 N·m). For firetrucks the revs waere increased to produce 299 hp (223 kW) at 3000 rpm and torque was increased to 630 lb·ft (850 N·m) at 1600-1900 rpm
