I stay out of OD in mine when towing.I was wondering about the most efficient rpm range for towing with the 454 Vortec. I’ve been keeping mine at ~2500 in third gear. Maybe that’s too low.
IMO, the 454 is not a efficeint engine in MPG, but it is quite efficient for a towing engine, as far as power is concerned. There is no good mpg option.
I disagree, I think it has more to do with the weight of the trailer, as it pertains to towing.Depends on the cam and cam timing.
I think that is the best setup for al around rig. Mine has 373, and when towing our old camper, 6000# dry, I would cruise at 60-65 in third gear. In the hill see sometimes downshifted to 2nd. Only time we ever needed first was going up black mountain, in a traffic jam on the mountain = not fun.Thanks. It’s a bone stock ’96 with 4.10 gearing and a 4L80e.
If H ad one thing to change about mine, I would go with 410's or 456" or maybe 488's
