so no higher then a 2600. thanks everybody

 

the stock HD converter should brake and flash stall to about 2500rpm, no need for a converter with a small cam.

 

weve put a comp 212 218 low lift version in an HD, the guy says he tows alot with it and said he needed a torque cam, so we put that cam in and the guy says he loves it, said its great on towing

 

ok cool. great info guys. Larry

 

FYI-I run a 216 Cam on my 5.3L with stock converter.No problems at all.Still idles at 600rpm with no surging or stalling.I'm thinking an aggressive 220 Cam would work too.

 

When talking about towing, it is very different from N/A and no towing. While towing, depending on the size of the trailer, you do not want slippage from the trans, as this causes extreme heat. Stick to a stock stall, but opt for a multi-disc unit. This will help pull the trailer at low speeds (like from a stop light) and will not cause excessive slippage during shifts on the clutches/bands. With the multi-disc it will provide better holding capacity once the TCC is locked up, so unlocking the TCC will not be much of a requirement. You will only need to downshift, but can maintain the TCC locked.

As for cam choice, I would go no bigger then a 218-220. Try to get as much lift as possible though. Remember, while towing, you are not going to want to be at 4000-6000 rpms all the time. You will want to be around idle-3000 rpms for best towing. Good luck!

By the way, I have the low lift 212/218 cam, with Pacesetter LTs and I tow a 11,500 lbs (total, fully loaded) enclosed trailer. This almost the biggest I would go (cam duration wise).
