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
