Cam upgrade for my truck, '72 D200 with a 360

I guess I missed the towing/hauling part ......
on a sidenote;
I've never had a vehicle in over 50 years that was prone to "pinging". Almost every carburated car I have ever had was a Mopar tho; including my 1975 D100/318 ........... and almost every one of those was an SBM. I say almost every one, because there was this one exception, lol, a 1984Hyundai-Pony; but it burned anything, I mean absolutely anything, including several years old stale gas with a high percentage of diesel in it.
But you are right; I know nothing about towing/hauling, and had no idea that 33s were used for that with 3.55s.
Sorry I cluttered up your thread.

I'm sorry my tone was arrogant I shouldn't have worded my response that way, just the recommendation to run a higher-stall TC was a 'red flag' in my head, that's a big no-no with trucks so I ASSumed your knowledge was less than it is; also my fault for not mentioning the towing/hauling part initially. Like I said I agree regarding gearing, 3.54s (not 3.55, I just remembered since it's a Dana 60) and 33" tires isn't the setup for towing. You didn't clutter up my thread, you raised some valid points I just think the concerns about losing cylinder pressure and having my truck turn into a turd with anything but a stock cam are a bit over-exaggerated. I will look more seriously into re-gearing and perhaps swapping transmissions depending on how it performs.

@Bighead440 @70aarcuda what kind of weight were you towing? I intend to tow an open car-hauler trailer with my Duster on it so maybe 5000-6000 lbs. Really not that much for a 3/4-ton.
