Haha, I was reading this and I thought to myself, "why didn't 06Sierra2 get a TR220?" I wonder what a comparison of power numbers the TSP224 vs TR220 vs TSP220 would look like. And I also thought about Otter bro, he keeps saying his hot cam is a compared to yours, this thread got me thinking, maybe i should cam the wifes truck and not let her know

 

ha lol, ill tell her that your thinking about it so that way it wont be faster than mine. jk, i wouldnt do that. it would be an interesting comparison tho, but i think you should go fi for that truck imo

 

i have a TR224/112lsa in my truck with a 3200 stall. it drives damn near like stock. idles fine in traffic, etc... im getting right at 12.5 mpg all city driving

 

damn i remember commenting on this thread like a year and a half ago

good info in here

 

really a TR224? wonder what the biggest difference between this and the TR220 are. maybe higher powerband?

 

so the tr220 would be ok with stock springs

 

I would at LEAST use zo6 springs

 

Z06 springs are kinda stretching it depending on what you're going to use your truck for. If you race a lot and don't want to blow it up just because you skimped out on valvesprings just buy some 918's or duals.

As for the difference in a TR220/TR224, you'll see about 10hp more on the topend but the torque difference down low is why the TR220 shines. I like my TR224, but would do a TR220 if I had to do it over again just for the torque difference on the low end and the fact that I have a 2800 stall. If I had a 3200 stall, it would be a different story.

 

yeah ive been thinking about the torque being my main reason, might go with something i saw from comp that was i think a 218/224. i would probably choose a TR220 112lsa for more low end torque/power with a 3k stall since im running a 6 inch lift on 35's and will have 4.88's and a true trac.

 

I have no torque with my 4.8 lol. Even with 4.11's. just won't spin from a dead stop. I need a cam or something bad
