I certainly did not loose any low end torque with the small 212/218, just pulls better from of idle until 5800.

Agreed, I had the lowlift 212/218 and its a great towing cam. Power off idle to 5800. It was a great fit for my 2500.

I have the 212/218 low lift on a 5.3 and it pulls great, no loss of tq down low.

That cam should be a torque monster on a 6.0 as it should bring the power even lower. Hard to beat for a tow truck IMO

While it's possible that it may only give you 10hp at 2000rpm over stock, I'm sure by the time the engine hits 2800-3000 rpms the gains will be closer to 30hp maybe more so yes, a cam is worth it

when it gets down to the small stuff such has lift, how do you decided between 521 intake lift versus 556 etc?

low lift = less stress on springs, therefore less maintenance and less valvetrain noise. The plus for the high lift is a little more power.

How often would you have to change the valve springs on the "high-lift" version?

I have the 210 218 551 551 114+4 that is in my sig and love it it's the crane vinnci grind pulled great across mount eagle with a 29 model A on my car trailer, most of the time I leave it in over drive.

no different.

Ramp rates and spring height are the biggest killers for springs. Just make sure that what whatever cam you choose, that the springs have enough seat pressure for the cam.

I went over board with my setup. The best cam that I have had is the 212/218 high lift with the stock 317 heads so far. I pull a heavy boat and 4 wheelers also.

Now I have a L92 heads/intake with a TSP Torquer V2 cam, 3K stall, LT headers, 3.73 gears, and 285/75/16" tires (33's) It gets better than stock fuel mileage, and it's still fun to drive, even when I'm pulling the boat. There's a few vids of it on youtube

Still trying to decide. 210/218 versus 212/218. Pretty sure on the 114+4. Also not sure on the 520ish lift vs 550ish.

Else Im ready to rock n roll!
