But I'll add a few bits,hope it helps someone. Even at 3100lbs with 3.91 gears and 3000 stall converter the 268he gave near identical times to the 284mp cam low 12's 110-112 mph. The 268he cam was shifted at 5200rpm,the mp284 6000rpm. The MP really liked more converter and gear to wake up. I'd bet the peak torque with the 268he would be 3500-3800 rpm and peak hp 5000rpm for a close ballpark.I found the 268he also favored small carbs over carbs that work with hotter combo's.
