Is there any difference between these two cams?

TR220/220 and TSP220/220

I know TSP camshaft has Comp Cams XER lobes, but does TR's cam have them as well? Is one any better than the other and which one do you recommend? And also, should I buy new push rods if my truck will be just cammed, 3000stall, CAI, LT's, and BB Tuned?

Yes you will need new push rods as well as new springs. Look into the PAC springs 1218 springs here http://sdparts.com/details/pac-racing/pac1218

For the cam, I would go with the TR 220/220 but it all depends also on what you want out of it. The TSP will make more power (just a tad) and has more aggressive lobes, but it will also increase valvetrain wear more in comparison. Both are proven cams

There is hardly any difference in the 2. 30 thousands in lift and basically the same lobes. XER lobes for TSP and the TR lobes are a propieratary lobe but they are ground at comp and are very similar to the XER lobes. They are both proven and you cant go wrong with either.
You will need hardened pushrods as well as good springs. (patriot golds are hard to beat for the money 255$ with titanium retainers, and new seals/seats)

By the way I run the TR220/112 in a 5400lb. truck and it gets me from point a to b in a decent amount of time.

lift and lobe type are going to be the only differences i believe, both are good proven cams though

just curious, why dont you go bigger though? 224 or 228? i have a tr224 in my truck and i couldnt imagine having a smaller cam now....only bigger

ecsb z-71 a 220 duration cam is fairly big for a heavy truck like this one. Bigger isnt always better.

00chevyscott has an ecsb with a 228 cam and it runs like a bat out of hell, mine is an ecsb with a tr224 and im extremely happy with it, i just need a bigger stall to get the most out of it.

00chevyscott, has a 4000 stall not a 3000 and he also isn't 4wd, which weighs more

tr220 imo is a great cam. i had a tsp220 114, and it was real torquey. the tr220 can be ran with pac/comp or ls6 springs. Geoff at EPS can cut you a great cam too. I like mine. not as noisey as my other camsand is less harsh on valvetrain.. They have comp grind a special lobe like TR, which is who Geoff used to design cams for.

Hey thanks for the help guys.

454navy- I wouldn't want to put in bigger than a 3k stall because this is my DD & the added stress on my tranny might break it lol.
