As some of the older members already know that I have a heavily modified truck. After differential swap, transmission swap, second transmission installed, and a few other minor mods (sound, lights, ect) I finally got my hands on a LQ4 6.0. Next is parts, parts and more parts. Im looking to get the top end kit from trick flow. Kit number: Trick Flow® 550 HP GenX® Top-End Engine Kits for GM LS2 TFS-K306-550-470. I will also use ARP bolts on all items that are critical and hard to get to. The top end kit claims to produce 556 hp and 475 lb-ft of torque on a stock bottom end. below is the lnk to the dyno.

Here is the link https://www.trickflow.com/parts/tfs-k306-550-470/documentation

Dyno on the top end link https://static.trickflow.com/global/images/chartsguides/t/tfs dyno tfs-k306-550-470 2014c.pdf

Next will be the bottom end. I plan on getting the TSP 402 stroker kit. Which includes TSP Forged 4" Crankshaft, TSP 6.125" H-beam with ARP 2000 bolts, Wiseco 4.005" -3.0cc Flat-Top (10-K464X05), Please Include Coated Clevite Main & Rod Bearing Sets Balance Rotating Assy., 24x reluctor wheel, standard wrist pins.

I'm reusing my a/c compressor. I'm adding electric fans, 200 amp alienator and a set of headers. Power steering I will try to keep.

I up graded the rear diff from a 8.5 with 3.08:1 to a 9.5 14 bolt with 3.73, Detroit locker and G2 diff cover. took out the nv3500 and added a nv4500 mw3 and gearvendors. converted the front from 5 lugs to 6. 2007 Yukon 17 in rims. no its engine work then suspension. lastly paint n body. interior.

Update on the project. I just received my wiring harness and computer. Now have to look for the IAC chip inside. If it is there I can use what I have in the truck far as cruse control and throttle by cable. If it is not then I have to order the proper foot feed for it and do some rewiring on the trucks harness to work the cruse control in the ECU.

I'm also looking at a starter, Alternator, Fans (flex-a-light 280), MAF sensor, building a cold air intake, Fuel pump (50 psi to power the 45LB-hr injectors for 43.8 psi), and using the power steering and A/C from the original.

Just a thought but I know the LS1 in the 4th gen Camaro was cable driven throttle and cruise. Maybe you could adapt some of that stuff somehow, get some PCM programming from it, etc? I don't know a lot about that sort of thing but maybe a few pieces from the same engine family may help?

I would have to go with an earlier ECM and harness. they had 4 different harnesses and two different ECMs

The wiring harness I received from the bone yard was oily. Must...Clean...it. :mad:

Update on the build. After being overseas on and off for the last 3 years and not to mention things keep breaking while am gone, I am starting to tear down the LQ4. I will have it torn down and begin inspection. After I return, I will have the block worked by a machinist and also, If the MOD Gods permit, have the rotating assembly in. I will be taking pictures to share in the fun.

Ok, for now I cant do anything money wise till I return from Jeddah, KSA. But I have decided not to do the stroker crank. I will be having around 475+ Lb-ft with the original crank. What I will do is still do a piston, piston rod, cam and heads upgrade like planned, but for a 6.0L. with this setup I will still make close to 600hp. Not sure yet. I will be first cranking it up on the engine dyno. I rather it self destruct there then in my truck. When I return from my business trip I may still decide to do the stroker. Which if I decide to put the vortec max logos on the truck and the engine covers then they will think there's something up with an engine with head and cam change making 600+ HP. but the stroker kit is $1900. I think if I research more and see how much more for the crank versus just the pistons and rods. Any thoughts?

Which one would look better in a blue truck?
 
#16
I like having a little contrast, and my TB has the white gauge faces, so I'm a bit biased there.
 
#17
I personally do not like white face gauges.

I'm kind of leaning on the black face. Just not sure at the moment.

Teardown has started on the engine. My wife and I have been talking about it and she convinced me to drop in the 4" crank and change the displacement from 364cid/6.0L to 402cid/6.6L. When I talked to trick flow, where I'm getting the GenX 225 heads and cam combo, they advised me if I keep the displacement the factory then my output will be around 550HP and 475ft-lb of torque. They then told me that if I did the stroker crank then it will be well over 600HP and 550ft-lb torque with 11:1 compression. We decided that we should rename the truck. We thought about Max. Then a co-worker asked me about supercharging it. My first thought was to call ProCharger. They advise me to use premium gas and 4lbs of boost would get me little over 700hp if I had a static HP of 600. Kevin advised that I lower the compression about 9.5:1 and add 8-9 boost and will net 840hp at a base HP 600. But I know it will be more than 600hp with the crank I'm dropping in. If I SC it then I can rename it Mad Max. Thoughts?

Another issue may come up. would the frame hold the power? Another gearhead like myself that works at O'Reilly Auto parts suggested to fully box in the frame and add cross members. Thoughts?
 
#24
I would think the frame should, but a little more rigidity couldn't hurt nobody. And it is probably easier to do some of it with stuff apart.

They where just worried about the frame holding that power without twisting. I told him if I don't do the drag slicks then the tires would be the ones giving. one co-worker asked if I was trying to kill the Hell Cat Challenger. I told him I could give it a run for its money with it along with towing and hauling. Would be funny to be hauling a load and I'm in his rear view. That would intimidate me. This guy in a pickup, loaded and I cant leave him. Honk the horn at the challenger and tell him to move out the way.

How about project Big Guns?
I have asked many people and they all agree with the Max engine that Mad Max would suit it well. Except on guy thinks I need to add spikes and random metal pieces to make it look like it came from the movie.

In other news, I have been working on the wiring to make it a stand alone. Wife and kids is leaving in a week to see her mom and our granddaughter, so I will have more time in the shop. I still have to finish the other lawnmower and finish the Tanker on our volunteer fire department. So I have a lot of things going on and not a whole lot of time. So, I'm still debating with myself about the supercharger. If I do it then I would be considering changing the diff gears from 3.73:1 to 3.42:1 knowing I would have 800+ HP. Can you say sleeper?

Ok, update. I have ordered suspension items for the truck. I'm tired of the rearend walking when I get on it to enter the freeway. While I wait on them I will be taking the axles donor springs, which has one more spring then the trucks original springs, and replace the bushings in them and paint them to match the axle housing. On order is Hellwig rear sway bar and tuff country traction bars. :celebrate::satan:

On another subject, I was talked out of the procharger for my build. the distributer told me unless I want to haul a smart car while blowing my horn to signal a dodge challenge hell cat to move out the way that the naturally aspirated vortec max stroker with the already drivetrain setup would be plenty enough power for red light to red light douchbaggary.
