I havent ordered the converter yet guy at circle D said I could go up to 3200 with the trailblazer 278 converter. I'll opt for a 3200. I've enjoyed the sleeper effect of a quiet exhaust in a 6.0 sonoma but it's time for a change it's been status quo since I finished it sometime in late 08 early 09 and has been a stone reliable daily driver as it was.
Whats the overall thoughts on the 228 based on the overall parts in the truck should it prove to be a nice all around cam. I'm after a noticeable lope, decent torque down low to get moving and fairly auto tranny friendly. As far as the LSA what will be gained lost etc going with 112 over a 114?

Thats the same converter I have. The lsa is only a idle thing I went 112. My truck is used as my company truck and i drive ALOT. Since the cam swap Ive done nothing but change the oil and drive the **** out of it. Its not uncommom for me to put 3000 miles a week on the truck and have had no drivabilty issues. Runs great and fyi i the motor had 198,000 miles when i did the swap. I have clocked 10,000 since then. I did cam, springs, oil pump, lifters, lifter trays, headers, stall, and e fans. I will be spraying a 200 shot in the near future just to see what happens. I have a lq9 ready to go if I scatter the 5.3 in a million peices. I beat the living hell out of this 5.3 and will continue to unil it blows. I want to see what the limits are of a high milage motor to prove a point.

Lower the LSA IE 112 more lope correct. higher LSA smoother idle.
LT's in a s-10 are just too big of a pita for what I use it. I've got the sanderson shorties and dual magnaflow spun metallic cats with a dual in out magnaflow muffler

The LSA on the ls6 cam I have is 116 so based off of the above and what the guys at TSP are saying going with a 112 LSA looks like it will address my major gripes of the LS6 cam. Mainly it's a dog out of the hole if you nail it off of a light. But it could be crippled to because right now I have a converter out of a 05 4wd truck in it also. Soo with a cam and converter swap she should be a complete different animal. Fingers crossed

With a good converter alone it will be a different animal. My 5.3 blows my tires off. No problem getting going from a dig. Once my turbo goes in, I don't know what I will do

The 228R is a good well proven cam. The big negative I see with sticking it in a "stock" 6.0 LQ4 which is only 9.4:1 compression ratio is the DCR with the 228R will be a low 7.3:1 which takes a hit in the torque department.
