Well I am currently in the process of building a motor for my LBZ. I have a long block currently in the making, while the motor currently in my truck is going through its paces. Anyhow, so far I am planning on carrilo rods, fingers oval bowl pistons, i have social 3388 cam, going with my stock crank (going to key it), ARP main and head studs, ATI super damper, 60% injectors, and push rods.

My questions are I cannot decide on what air setup would be best for my application. I would mostly daily drive this truck, and tow more so in the winter months. I do enjoy sled pulling maybe 2-3 times a year and attend 1/4 mile drags about 2-3 a year as well. I want a truck that is capable over over 750HP. Can be driven mostly day-to-day, and still be in the 11 second range for 1/4 mile, all while be a fairly reliable truck.

I am torn between running a HSP twin turbo kit s480 over danville 3794, or running a single s366 billet wheel or something possibly bigger as well. :/ I love the that twins when towing are very nice, but I also like the fact of a bigger single to go nuts with lol. I am looking for input from people who have either set up, or who have experience with both!

Thanks in advance!

My personal opinion is to stay away from the 366. The s468 is a lot stronger turbo and is rougly the same cost. A single s475 would get you what you are looking to do for power. Maybe members that have that will chime in on how it will tow.

a stock/475 is almost in that hp range and you are looking at a lot less cost with minimal loss of spool up which means great towing and daily driving manners. Get's my vote everytime!! :thumb:

Lag is the devil, just saying ;)

I read some where that the s475 and stocker set up was pegged out at around 700HP. Being the stock charger being the restrictive point. I figured with danville's new drop in 3794 is would be a helluva upgrade for a twin set up. :eek:

That sounds pretty accurate. My point was to stay on the fast spool side of the setup, you will appreciate it when you are done :thumb:

Also depends how serious into sled pulling and drag racing you are. Twins will often put you in a separate class and a smaller twin setup will get beat up every time. But if you're just going out to have fun then it doesn't matter. I'd definitely go with a single s400 vs S300 if you're going to go the single route.

I would definitely call around and see if you can't get some of the more experienced shops to talk with ya a while, Mark Larry or Chris over @ Danville, JJ @ DHD, Lorenzo @ Socal (or Guy if he's available) and Scott over @ SDP are all good dudes to talk to. Then there's the Hucksdorf Diesel crew, Fleece and a bunch of other credible shops to get some good info from as well...

Don't forget there's always tuners that are willing to share their knowledge too, I've always liked talking to Bob over @ DuramaxTuner and Mark @ Danville.

As for turbos, I've only had experience with a couple singles on a stock engine, and one was the VGT72. I really liked that turbo but it didn't have an efficient turbo brake and I wouldn't consider it a "towing turbo" but it seemed to do everything else well. I always get hung up on wether to run a Danville VGT or a Fleece VGT, due to the customer service I receive and the forum backing here I always end up with a Danville unit, but I recently saw a guy put down 850+ whp with a Fleece 68...

Like Andy said, depending on what you wanna do sled pulling, you'll be fairly restricted as to what turbo(s) you're gonna be able to run/compete with depending on what class you wanna be in, so the rules with whatever class you'll be competing in will guide you to your decision, considering most your time with the truck will probably be street and towing time you'll have take into account pulling a sled and pulling a trailer don't really have the same build dynamics...

For the most part, I like VGT chargers. they have their drawbacks when you start talking about MAXIMUM performance and potential failure points/more to go wrong, but really they offer so much all around capability I really feel like they're hard to pass up. Especially when you take into consideration what it "can" cost to swap to a fixed charger, add in an exhaust brake kit to match what a VGT offers and you really start pushing the ol budget...

I think you're on the right train of thought considering the Danville stg2 3794va, it would be a helluva charger to twin and I believe it will spool almost as instantly as a stock VGT yet have allot more potential, both as a single or in a twin setup. I bought it earlier this week and hopefully will be receiving it tomorrow and will be installing it and my re-man engine tomorrow night. You can be sure I'll give a full report of what I think of it soon, but I've got to get some updated tuning and break my engine in first

I'd probably add an AF cam instead of the standard cam, throw in a set of billet mains, billet flex-plate, billet input shaft, SoCal beehive valve springs, a trans brace and transfer case pump rub kit and I'd definitely add a better rear diff like an Eaton Detroit truetrac into the mix too:thumb:
Good luck man!

I'd also run the AF cam, and go with the 3794/S480. Best of both worlds if you want to tow. Might affect what class you will compete in but if you just do it for fun it probably isn't too big a deal.

I ran 11.6@119mph with a stocker/billet 475 twin setup with 40% inj on a stock motor and normal weight on street tires with tame tuning. It had a junk trans at the time and wasn't out of air yet. I never went back to 1/4mile but picked up 4 mph in the 1/8 with a good trans. The setup spooled awesome too. The 3794/480 should be good for over 900 though. I currently have the Danville 3794/483 and it does really well too.

I decided my trucks fate. Run a s475 over 3794 set up and make it a tow pig, nothing crazy with the motor. Then find a blown up regular cab truck and put the lucky motor In that and make it the drag racing/sled puller I would want it to be.

Anyhow, if anyone has a lead on a blown regular cab let me know!

You might be better off just twinning the stock turbo. Probably spool a little bit faster and since you won't be pushing the motor it should push more than enough power..

Thats what I have been thinking.... Now would a safe, reliable, daily drivable, set up for this truck I was thinking, HSP 475 over stock, ARP head and main studs, keyed crank, 3388 cam, 30% over injectors, lml manifold, and lb7 up pipe. Now the main question is should i keep the lbz rods and put de-lipped lb7 pistons in? or go with carrilo rods instead?

Im assuming hamilton makes the valve springs? and i would probably put pushrods in it too. I have a MA water pump already in the truck when my factory failed.

Hamilton or SoCal. The S475/stock is a good combo for what you're planning now (towrig).

Depends how hard you're going to run it. I think I would just for piece of mind.

Wouldn't run it as hard as i do now (sled pulling, drag racing, 2-tracking) lol and thats what I'm torn on doing, chance on running it with the semi-stock internals or have the pice of mind if i ever turned more power out of it for what ever reason.

are the titanium retainers worth it over the steel ones?
