i don't know a lot about gmc v6 motors, so i googled it. wikipedia taught me this:
Quote:
The 477.7-cubic-inch (7.8 L) 478 was one of the largest V6 engines ever built. Gross output was 254 hp (189 kW) at 3700 rpm and 442 lb⋅ft (599 N⋅m) at 1400 rpm. Bore and stroke was 5.125 in × 3.86 in (130.2 mm × 98.0 mm). It was introduced in 1962 for the 6500 series trucks.
great googly moogly 478ci, 254hp w/442ftlb of torque in a v6
that's stump pulling torque plus, my ramjet 350 only has 400ftlb of torque

start looking for the 702 v-twin if you want a unique gmc setup
