My 5.9 Magnum is eating 2 quarts of oil per tank. Time for a new mill.
You are correct. In hindsight, I doubt it was even 360 hp. Wishful thinking on my part.
Years later, I built a 408 stroker based on a Magnum with Hughes Super preped heads with a bit of extra port work from them. I ended up running a Hughes custom ground .555" & 246* dur In .540 & 252* dur Ex on a 108* LSA.
On a chassis dyno, it spun out 382 hp & just over 500 ft lbs of torque at the wheels. It has an automatic in it, so I figure it has at least a 15 % loss through that. Doing the math nets just under 450 hp & 594 ft lbs of torque at the crank. Not bad for a street car. Especially since it has a 2.76 to 1 1st gear ratio, a 3800 rpm stall lock up converter and 3.91's with Nitto Drag Radials.
