Bump Sent from my HTC6500LVW using Tapatalk

I might have one laying around, but it doesn't have the filter Sent from my HTC6500LVW using Tapatalk

This also depends on the wiring harness that the owner goes with. Sent from my HTC6500LVW using Tapatalk

I have a pair of ls6 243 CNC'D by cbm heads. They have patriot dual valve springs, Manley valves and have been inspected and cleaned as well as decked .004 to make sure the decks are square. I prefer local pick up due to the weight, but if the buyer is willing to pay shipping I can do that also. They sell for 1700 plus a core charge, get them here for $1500. With no core charge. Here is the info on them... http://store.custombuiltmotors.com/engine-internal/cbm-motorsports-ls6-cnc-ported-complete-cylinder-heads.html Sent from my HTC6500LVW using Tapatalk

I have the stock amp, and I can even include the Pac Bose add an amp with it Sent from my HTC6500LVW using Tapatalk

This too is exactly what I saw. Sent from my HTC6500LVW using Tapatalk

Doesn't the hummer h2 have a center mounted shifter? Sent from my HTC6500LVW using Tapatalk

It depends on how mechanically inclined you are. It requires removing the rear cover, wheel, caliper, rotor and axle clips, then axles. Then the axle seal, and then bearings. Sent from my HTC6500LVW using Tapatalk

Sounds like axle bearings are going out. Sent from my HTC6500LVW using Tapatalk

Replace the stock valve body plate with the thicker transgo, and use the smart sunshell instead of the beast. That will be a food start Sent from my HTC6500LVW using Tapatalk

The cliff notes to MAF vs SD tune is that a MAF tune tunes in real time based on actual air coming into the motor. The O2 sensors simply verify that the maf is operating properly and make needed adjustments if necessary. An SD tune goes off of predicted values using multiple different sensors and tables.

I think you will be fine as long as you shift the truck earlier. Try using your tow/haul button (as long as the t/h settings haven't been changed). By default it shifts sooner than normal. Try it, if it improves your time, you're holding gears to long. Sent from my HTC6500LVW using Tapatalk

Not doubting your tuner, but you might want to recheck the tune. And second just because a cam is advertised to "xxxx" rpm, doesn't mean you should shift it there. If the truck is no longer pulling in one gear, shift it. That intake manifold and cam are not well suited to each other. One is a high rpm flow, while the other is more of a low end torque towing application. (cam) Sent from my HTC6500LVW using Tapatalk

That's a 4l80e not the 65 with an nvg149, o.p. we only have the one speed sensor that is mounted on the output shaft of the transfer case. Sent from my HTC6500LVW using Tapatalk

don't forget the much taller 1st gear. Did wheatly know the truck had the 80, the 60e and 80e require different calibration files Sent from my HTC6500LVW using Tapatalk

IIRC the 4l80 and the 6l80 have the same size output shaft, so theoretically you could use the same input gear to mate the nvg149 to a 6 speed trans Sent from my HTC6500LVW using Tapatalk

Yes it's possible, but you need the complete interior harness from a 4x4 truck to do so, or just cut and splice wires and use a relay to trigger the 4x4 actuator Sent from my HTC6500LVW using Tapatalk

Slight correction, the square/rectangle ports will always have more volume therefore low end torque, the cathedral ports will always have more velocity, hense why the cam options are so different and why intakes such as the holley and vic jr and all aftermarket intakes favor the cathedral ports. And this is why there is no good aftermarket support for the newer intakes, it very hard to beat what the stock intakes are providing. The best bet is to pick a goal, and get parts that will achieve that goal. No need to just buy aftermarket components and expect them to work.

The higher the number the colder the plug. Stock is a 5, an 8 would be 3 steps colder than stock. I would do A 7 or 8 at 20# depending on the fuel. The crappier the fuel, the lower the plug Sent from my HTC6500LVW using Tapatalk

Truetrac is sold Sent from my HTC6500LVW using Tapatalk

It has less than 3k miles. It was on a truck that later on got upgraded to a 9.5" rear. I did work for him and took his old rear end as payment Sent from my HTC6500LVW using Tapatalk

Why not go to eficonnection.com. (i think that's what the site is, I'll verify in a few) get the sbc conversion kit to run an ls1 pcm with coils... Then do a standalone ls1 on it. Should work tons better than the other aftermarket stuff unless you are going electromotive or something high end. Sent from my HTC6500LVW using Tapatalk Should cost about 800 less if you have most of the parts like coil packs and a pcm Sent from my HTC6500LVW using Tapatalk

These wheel look like they where chromed by someone. This could also explain the weight. However I used a regular bathroom scale to weigh them, not the most accurate. Ttt, and no one here is interested in the truetrac Sent from my HTC6500LVW using Tapatalk

If it was an original clutch fan truck you won't have any issues Sent from my HTC6500LVW using Tapatalk

29lbs vs the stock sss wheels at 42lbs Sent from my HTC6500LVW using Tapatalk
