My LQ9 Build
#72
Imo don't waste your time with a heavy 11" TT2600. Not worth the swap and you'll want something more later. Start off with a snappy, light, 9.5" SS3200. Your MPG will be fine and these regular cabs get moving easily so MPG won't suffer much more. Last tank I got 12mpg mainly city mashing the truck everywhere, since I don't DD it when I drive it, so I could see 15 easy taking it easy. I get 17-18mpg highway at 80mph.

Actually, for the buck, if you want a tight converter like the Yank TT series I'd recommend a Circle-D upgraded trailblazer converter, which is their offering that is comparable to a Yank TT, and is only about $375 brand new. As the converter gets smaller (10.5", 9.5"), it generally gets looser, which means it will take more accelerator pedal angle to get it moving, and therefore more fuel consumption, even if it's only a "little bit" more fuel consumption. Not that there's anything wrong with Yank, I just prefer Circle-D as that's what I have and am very happy with. As I mentioned above, I've driven Yanks and been very impressed also.
I chose a Circle-D billet multi-disc for strength first and foremost, as I have an LQ9 sitting at my pop's shop just waiting for me to come into enough dough to build it lol. Chris at Circle-D recommended the 258mm which is noticeably looser than the Yank TT that I've driven, both converters being 3k...actually the Yank flashed a tad higher than my Circle-D (maybe 100-200 rpm), but the engine/gear/drivetrain are different on both vehicles also.

I think the trucker is going to a pretty good option. I know I can always go bigger in the future if I want to. The LQ will eventually have better heads on it too. Just trying to hold on to my budget. I have only driven a few cars with a higher stall converter so I'm not sure what I'll like, converter-wise. I'm also going to be sprayin' on this so it'll have more in it.

How many cam swaps have you done? Haha. Are you on like three or four?

218/222. Zero low end issues. My truck 1/8's like a 12.2 truck, but runs 12.6's, it actually needs more cam for after the 1/8th. Pulling a local residential steep hill at 30mph I'm at 2500rpm with a SS3600 (unlocked of course). Get's up and goes with light throttle no problem. Not to mention my trucks still considered fairly mild, stock cats, same headers you have, PASSES SMOG etc etc.
I've done the whole mild thing. I was a blinded believer that you can't DD a semi aggressive street setup. I was wrong. My trucks very street friendly and 14-18mpg is pretty damn good for 450hp.
Reason I bring up mine is because our platform is basically the same.
