Just what I was planning to put in my 6.0 in a few weeks a 224 but should I go with Thunder Racing or Texas Speed? I think the TS has a little more lift. Thinking about staying with the stock stall though since I have a 4l80e. Btw its in a rcsb 2000 silverado.

 

good thread , i was just googling about the tr220 on 5.3s
how much do you guys think ill do on dyno with mods on sig + the tr220 cam
i also thought that more LSA means lower end...off idle cam
i was thinkin of a 220-220 with 560 of lift and 116 lsa for lower end torque...i really lack that with my heavy truck and when going to 33s agine i want more low end for dune bashing

 

Good numbers! I just did a tr220 swap with a buddy of mine on his 5.3. He put down 323 hp and 389 tq! Good cam choice

 

Tr220 ftw!

 

Sounds like the tr220 is a well proven cam! Geoff knows his stuff for sure. I will be getting a custom spec cam from him once taxes come back!! This is making it even harder to wait....

 

TR220 is still a top performer in the 5.3's...Good number's and very driver friendly.

 

update for thread readers i installed a custom spec 219 222 .607 .602 111 and got 365whp 369wtq

 

Wow, nice numbers. What's the curve like? Got a graph of that thing?

 

nice numbers . . . is that with a cut out, or with a muffler?

 

Who specd the cam?
