Can you make the vids public

Here's the cam chop after install with just the stock headers, nothing else. Untuned. Loud as hell and sounds like ass lol.

And here is how the Duke sounded the next day with the exhaust back on. Stock headers, primary & secondary cat delete, and a 40 series muffler.

The sound outside the truck is perfect, loud enough that people will deff notice and hear it chop but not so loud that I worry about waking my neighbors or can't cruise comfortably inside the cabin lol.
Great results! Has the idle speed been raised from 550 rpm (stock). If not and with you already making 90% of max torque at 2500 rpm a higher stalled TC isnt necessary, esp if you plan to tow alot

And obviously reusing all of the alpha engine accessories and their respectivd bracketsLots of fun stuff and miscellaneous items in this post.
New in box Rancho 4" suspension lift kit. Was very excited when this showed up.

Being one of the few to be able to snag one of these overlooked kits made me very happy. I consider myself very lucky to have one after actively searching for used kits at the time and to have these just "pop-up" years after they stopped making them.
Trip to the drag strip using the T to tow the race car. The total weight is near the manufacturer limits but she seems to do just fine.

For all you a$$ fans :wink:

Around this time, I also did this mod to the lower side-trim piece on the drivers seat. Mine had started to sag and turn on my seat heater to High. Didn't take a pic of mine, this is one that I found online to address the issue. You put a screw in through the trim panel and into the seat plastic behind it to keep the panel from slipping down.

New tires showed up for the lift install. All loaded up for their temporary new home until the lift goes on.

I went with 35.00x12.50x17 Toyo MT tires. They are a bit heavier than a Trail Grap in the same size fyi, but sturdier construction evidently. Really wanted to go with a 37" tire but since I love to daily drive this thing, I figured to table that idea lmao.

And here are the new wheels! I absolutely love them. Method Racing 312 in matte black and made from solid A356 aluminum.

Left these with my buddies over at K9 Motorworks to mount and balance for me.
Also pulled the trigger on the Lased Designs dual Optima battery tray. Needed to replace the battery anyways so I purchased two and installed the new Optima Yellowtop in the truck. Mine is still wrapped up and in the box, here's a pic of how they look from German of LD. I need to get around to installing it, the battery and tray have been sitting in my garage for quite a while now lol. :no: Still deciding on what color to powdercoat it. Probably white or black. Hmmmm...

And finally... dropping off a couple of blocks to my engine builder, MPR Racing Engines. One is my buddies. Coyote 5.0 and the other is an aluminum 6.2L LS3, for The Duke. Heh-Heh.... I just well can't leave it alone and I scored a nice little deal to build this thing. For those of you don't know, the 6.2L LS3 will drop right in an Alpha. Just need to re-use the Alpha LH8 specific oil pan and the Alpha LH8 headers.

More to come... when I feel like posting :giggle:
This is gonna be bad ass when it's done. Nice choice on the wheels. I hope it all goes smooth. Best of luck to you.
I strongly disagree. A turned down output shaft has not proven itself on the 6l80 with anything other than a stock 5.3. We are going to try this on a 6.2 we are building in the spring but I don't have high hopes long term especially with towing. We have a fully built 4l65e by PATC in an h2 on 37s and we regularly tow 8-10k pounds without any issues.Skip the 4l60 and do a 6l80. I was unfortunate that my trans broke down right after my engine swap and funds were dedicated to the swap itself so I decided to rebuild the 4l60 (big mistake)

They are used LS3 castings that I had MPR port with Manley stainless steel intake and exhaust valves, and had the deck milled just a bit to bring back some of the compression lost from the pistons. With the new valve chamber volume, head gasket, and pistons, the compression ratio on this motor is going to be 11.2:1. In comparison, an LS3 engine has a stock compression ratio of 10.7:1. So the 11.2 CR is going to be perfect for an N/A truck.
Higher compression would need more fueling dropping mileage
Or higher octane adding to fuel costs
Am I guessing Right?

Im sure when you do that full throttle "engine break in" launch you will be impressed. When I got me engine it said to do one after 100 miles, glad I was driving on an empty service road the way the truck jumped and pulled.
How much did that converter set you back? I had a 3200 converter but not billet, but on hindsight I shouldve went 2800 since my trans really heats up offroad and easily goes above 210* even with a 40K trans cooler. If I really pushed my truck wouldve be surprised id hit 250*.
Hoping with my axle swap to 4.56 Ill solve that issue (or reduce it significantly) otherwise im gona have to either add a second trans cooler woth fan or change to a lower converter.
As for your ride, if you set the ride height to rancho specs then you probably were riding on the bump stops. Raising it probably reduced contact and that improved your ride quality.
