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

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.

I had 31" tires and 3.55" gears with a 727, so it was spinning a few RPM at 65mph. I have towed a 16ft steel trailer with my 5000lb (NHRA scales) '76 GranFury wagon on it, but normally no more than a 4000lb car and trailer. I towed a 4000lb (car and parts) 1961 Plymouth Belvedere 2dr htp from past Windsor, Ontario Canada to central Georgia on I-75 back in 2004 with it, but it was mid December and very cold. Towing around Georgia in 100* heat wasn't ever really a problem though.
