Triple Black Attack: 1970 440 6-Pack 'Cuda - /BIG MUSCLE
Each and every muscle car enthusiast has that one experience that has
helped define the way in which they view the automobile. For Northern
California's John Cross that experience came by way of riding in the back
of his cousins 1970 440 6-Pack Plymouth 'Cuda when he was a kid. It was a
car that provided him with memories, stories and of course, a goal - that
being, to one day own the very car which got his engine running all those
years ago. It's now 2012, 42 years after that first faithful ride in the
very 'Cuda you're about to see. This time however it resides in John's
garage, not his cousins, which can mean only one thing... Sometimes dreams
do come true.
Dyno pull of my 318 stroker (390) Dyno pull of my 318
with a 4" stroker kit, bringing the displacement to 390 cubic inches. It's
a very simple and mild street engine combo, consisting of 9.3:1
compression, a mild hydraulic cam, and bowl ported but otherwise stock iron
magnum truck heads. It made 367 HP @ 5,300 rpm, and 407 foot pounds of
torque @ 4,100 rpm. This engine is going in my 1989 Jeep Wrangler.
Special thanks to Performance Only in Delray Beach, FL for the excellent
machine work, building of the engine and tuning. Thanks to Eddie "Elvis"
Miller at The Engine Works for working the Dyno and providing tuning
