yeah, the 212/218 does exist in a high-lift version, but if has completely different valve events. From the results others have posted on here, I don't think it's as good of a performer as the 212/218 low-lift version. Its not the higher lift that does it, its the different valve events that kill the low end that the cam is supposed to be known for. If it were my truck, I'd grab the low-lift version and some higher ratio rockers if you want to take advantage of the flow characteristics of your heads at the higher lift values.

Don't go "off the shelf" on a cam, especially since you are looking for something very specific. The extra money spent on a cam that was designed for YOUR truck and YOUR needs is well worth it. When I did my cam I wanted a cam that made the power of a TR220 but had the power band of a Comp 212/218. What I was given was a 216/222 111+4 (XE Lobes). The reason I wanted that criteria is because I was camming a heavier 4x4 truck where the TR220 is used my mostly 2WD guys. Contact Patrick G (LS1 Tech) and let him know your goals. For $25, he will spec you a cam exactly to your needs.

I'd throw darts at a piece of paper with squares drawn on it and duration and lift numbers written randomly in each square before I'd use a PG cam spec...

I do not know what you have against Patrick G or his cam specs but I feel he set me up with a pretty good cam considering my needs. Many people are out there who will do it and I am sure they are all good. FlowTech Inductions and Cam Motion are also very popular with the LSx crowd.

I'm not here to argue about cams or anyones wants/needs. Very rarely do you see a 4x4 truck (with 5.3) go with a TR220. Those who do also do not run a 2600 RPM stall. My goal was to not lose any low end, gain a bunch in the midrange and be able to pull to 6250. I feel that I have a great all-around cam with plenty of power under the curve. I have a higher dynamic compression ratio with my cam and a more usable, daily driver power band. Would the TR220 make more power than me? I am sure it would. Would the TR220 lose low end over my cam? I would be willing to bet it would. Would I like to go with a bigger cam? If I did it all again knowing what I know now, I would but I definately would want my LSA to be low with lots of overlap to bring my power down lower. Idle was not of concern to me, but making power where I could use it was.
