Anyone seeing any differences in the texas speed 220 and the thunder racing 220 cams?? so close in lift .551 and .581 both on a 112 lsa. Thinking about going with one but what do you guys think about these 2? Or maybe something in the 212/218 range better for me being a big heavy beast. No major towing will occur FYI.

 

Did you search? IIRC, there is a huge thread on this.

 

I've looked around. still no difinitive answer's though. Most everyone is 2wd too. Sorry if im being a pain in the ***.

 

not much of a difference, if i would do either one, it would be the TR220 cause you can use the LS6 springs, which will do for a quieter valvetrain...

I used to have the 212/218 on my z71 ecsb, it worked great!! but mine was on a 114lsa, and the downside of it was no lope, but thats just me cause i like to hear some lope, other than that it was a great cam for big truck, if i would do it again i would custom spec it with a 112lsa..

Interesting how close companies grinds are!

 

diggin up an ol' thread, it's come time to order a cam...i've decided to go with a 220/220 on a 112 however still not sure whats the better call the TR220 or the TSP220 cam? What do you guys think? Ive searched everywhere and cant seem to find out much on difference of opinon's between the two.
Thanks for your input!

 

the tsp will make slightly more power and a smoother idle. The downside is more valvetrain wear.

 

more power and more valvetrain wear due to the XE-R lobes?? what makes it idle smoother?

 

more aggressive lobes - smoother idle

the bottom line is go whichever one you can get cheaper.

 

I see, well there is only like 10$ diff. in the package's including the 918's and 7.4 hardened pushrods! Which one would you go with?
Thanks for the help! Much appreciated
