It pulls my 6,000 lbs Jayco travel trailer down the highway at 65-70 mph in overdrive at about 2,600-2,800 rpm with no issues. About to swap the intake for an Edelbrock proflow with a 90mm forward facing LS throttle body and put my Etec 170s back on after I had them surfaced(warped them when I overheated it a while back). I put down 290 rwhp @ 5,800 and 330 rwtq @ 4,000 with more than 300 rwtq @ 2,500 on a Mustang dyno that is super stingy. The Lunati Hotam with 4.56s pulls better in OD than the Marine cam did with 3.73s in 3rd. The tiny 196/206 marine cam only put down 230 @ 4,400 rwhp and 304 rwtq@ 3,400. When I hit a hill the thing only downshifts to 3rd vs 2nd before and I run up the same hill turning about 800 rpm less at the same speed. In the 3,500+ range the Hotcam has ALOT more TQ than the Marine cam.
That is certainly promising information!
