2004 Silverado SS 6.0 AWD LQ9 to LS3 Build
meistro57 replied to Carloss’s Build's topic in Engine Tech And Modification
I know this is an old thread but I'm going to chime in anyway. I have a 2004 SS also. I purchased a BluePrint Pro Series LS3 427 Stroker engine claiming 625hp at the crank. When I got that fired up, my transmission didn't last but a couple hours. I ended up swapping it out for a 4L80. A year later and my abusive driving habits, trans is still going fine. I did break other stuff downstream though When it breaks, I overkill the replacement. It stopped breaking now, pretty much LOL. -
Swapping out perfectly good 6.0 with LS3 7.0 Stroker
meistro57 replied to meistro57's topic in General SS
Looking back I realize that I’m going to need new flex plate. Do I need a spacer too? Or is that only when using older flat flex plate? I was going to buy an AcDelco 4l80e LS 6bolt flex. The 4l80 is going to make it friendly to make them tc bolts. Better than through starter spot. Stupid 4l60. They shouldn’t even exist in a truck at all.- 11 replies

Suspected transfer case problem
meistro57 replied to dyocis's topic in AWD, Differential, & Transmission Tech
I had the same issue. Turns out it was the viscous coupling in the transfer case being damaged. It would spin freely very slowly between the front and rear axles. I bought a rebuild np149 that stated the viscous coupling had been serviced. It can't be so that was BS. The rebuilt one had a bad coupling that was slipping internally. -

I just ordered a 4L80e. I will definitely revisit T56. Here's some info.. https://ls1tech.com/forums/manual-transmission/1941719-how-build-all-wheel-drive-t56-awd-t56.html -

Yeah I ended up ordering a 90mm with the square type plug. Plugged it all up and worked perfect.- 11 replies

Swapping out perfectly good 6.0 with LS3 7.0 Stroker
meistro57 replied to meistro57's topic in General SS
Yep, just like you guys said lol. I got it back finally from tuner on Friday and I broke it Tuesday. Today I ordered 4L80 advertised as 1200hp capable. I got the adapter mentioned here.. performancetrucks Is it worth spending the $$ for the harness adapter? How much different is the tune for the 4l80 compared to 4l60? Am I gonna need to get it back to the tuner? Should I ditch the in the rad trans cooling and get aftermarket since the existing lines might be too short? Do the conversion crossmembers work as expected? Better off modifying my existing one? What else am I in for that I'm not thinking about?- 11 replies

Swapping out perfectly good 6.0 with LS3 7.0 Stroker
meistro57 replied to meistro57's topic in General SS
That's what I ended up doing. The throttle body has a 6 pin flat connector and xlink has 6 pin square. From what I can tell I can just replace the connector on the xlink to the flat connector. They both have the same signals I believe.- 11 replies

Swapping out perfectly good 6.0 with LS3 7.0 Stroker
meistro57 replied to meistro57's topic in General SS
So far so good. Its running with a base, "break-in" tune with stock LQ9 injectors & throttle body using adapter plate. The specs from Blueprint engines for injectors and TB that were used on the dyno for this engine show 87mm LT5 DBW Throttle Body 42# injectors and returnless fuel rail When I bring the truck to the tuner with awd dyno (after 500 mile breakin), I'm going to swap injectors & throttle body to match what they used on factory dyno. The injectors are easy enough to get. The throttle body has me a bit confused. Is there a gen 3 t body in 87mm or larger? I can get a 4 bolt but it has 6 wires and not 8 like I have now.- 11 replies

Don't get a Jet tuner unless you already know what your doing. The support sucks. HP tuners seems to have a very large following with lots of examples and walkthroughs. I have a Jet tuner and it's so 90's. Even though it has usb it isn't user friendly. I will now buy the same as my tuner so I can load tunes emailed to me.

Yes I still have the 4L65E. It's been rebuilt and I know that's my weakest link. I told the guy to make it handle more abuse but I just made the decision few weeks ago to get this engine. If I would have shown him what I'm putting in there, things probably would have went differently. I really really would rather have a T56 AWD. I'll look into that after I break the one I have. I still need to replace the converter though to help maximize the added pleasure. I should just start a build thread about it. I have much work to do. The parts pile I have collected is getting large. I drive it daily when the weather doesn't permit playing with my other toys. I'll probably replace the exhaust this weekend then wait until the weather gets better to allow the unforseen down time swapping the engine.- 11 replies

What Transmission Comes In The Silverado Ss
meistro57 replied to ss454327's topic in AWD, Differential, & Transmission Tech
Find a new transmission guy. I had mine rebuilt last year for the same 04 SS and I beat my truck pretty good. I told my trans guy it needed to handle 700hp. I was planning ahead for when I replace the 6.0 with LS3 427 stroker. -
Hi everyone. I have a 2004 Silverado SS. It's pretty much stock, except for the trans and suspension. I've been preparing it for some torque. Yesterday I placed an order for a BluePrint Engines Pro Series Chevy LS 427 Stroker PSLS4271CT. They recommend a converter with 2200+ stall. I'm not sure what diameter I should go with. Has anyone in here had experience with anything similar like what I'm doing?
