I'll measure the caliper pistons for you as soon as the black paint dries..lol. These rotors are 14.17 tho.

Ok, Looks like they are about 2 1/4 with a measuring tape.
Well, i was going to do the brake kit sunday but something else came up, so i will do it next weekend. ... I sold my supercharger which is a tvs1900 and purchased a tvs2300. It gets shipped to texas this week for a regcab 4.8. I boxed it up like it came, stock injectors, stock intake tube, stock 6 rib pulleys. What made that happen and i never thought it would be so soon, out of the blue a buddy called and said he was selling his complete 2300 for a good price, i figured this was the time to upgrade cheap. To upgrade for less than 1k was the one statement that had me sell mine. The 2300 is the same except the top part of the blower has 1 more set of ribs, so its a direct swap with mine. With this i can step up from 2.6 to 3.2, with a 3.2 i'll have the same amount of boost. Eventually in a year or two when i do a motor tho i can put the 2.6 on and have 20 psi. A few things will contribute to that tho, i will upgrade to a 102 throttle body and go to a 5 inch intake and speed density tune.
This is awesome
Hahaha, it Will be Sunday. Picked up a new belt and the new blower pulley came in. Zpe stage 3 3.2 blower pulley. Might have billet idlers and tensioner pullies to if another deal goes thru
Swap went really nice, used my 60lb injectors and fuel rails. It's a little bigger in height and length, started and runs with the same time. 12psi was max and that's perfect for my stock bottom end. It pulls much harder and is way faster now. Pretty impressive, can't wait to pulley down one day and do 18-20 psi.
Also adjusted the coilovers to make it sit more level.

Looks awesome, every time I see this thread it makes me want to order parts to put the lsa blower on my blazer.
Thanks, I enjoyed the boost so much I ran my last supercharger to its limit and bought a bigger one...lol.(only since I sold mine an added 1k, way too much to buy new) It's addicting, this thing with the 2300 is a fricking animal. It flies, rather impressive. I only went for a few blasts and it rips...gotta have twice the steam as b4.
Everyone should have a boosted LS 
With less pre load the coil overs seem to ride better and smoother. I did a few data logs last night with my hp tuners, i used the same tune i had with my 1900. Being 2-3 psi less boost the tune worked pretty well. What i did see is the 2300 moved more air with less boost, with 30 degree less heat. Comparing the size the 2300 looks taller and the upper tub is 1.5 inches longer, so obviously it will move more air..lol. With a few wide open blasts the iat temps didn't break 90 degrees. It gets up to 100mph a whole lot faster...lol. I think with the 1900 and the small pulley built so much heat so fast it looked like more boost with the pressure. Now with the timing turned up and fueling adusted it seems like a whole different animal, Its faster for sure and seems to have more off the line. Still tuning, it still needs more work but its close. The 100 mm lingenfelter maf seems to still be working well, the frequency still hasn't come close to its end so no need for speed density at the moment.
On my way home from work on wednesday the motor started making noise in the right side bottom end, i was in a part of the road without a shoulder, on a busy 4 lane highway. I got it off the road but its real loud now. Something finally let go, not sure what yet. With how loud it is i'm surprised there's no hole in the side. Its a giant bummer, it ran so good for so long but it is a powdered rod motor and it was expected to happen but not so soon. So i have a few decisions to make, will it get a new motor or will it get a used newer strong rod 6.0.A low mileage 6.0 from a newer silverado came up but its a toss up. I've been looking and am on the edge of a new 370 or 408 short block. Talking with the guys at texas speed a 370 0r 408, the long block comes with shitty heads. So if i do a short block with wiseco pistons, h beam rods, k1 forged crank, arp bolts, tool steel wrist pins it won't be real cheap but then its done. With a forged short block i can put good heads on it with better lifters than ls7's. I have a connection on a set of brian tooley 255s that are ported,polished and the ports softened. If i do it this way i'll use my cam, lifters, timing set and all my covers. With my blower and 15psi..lol. It could be 7-800hp.
The decision 370 or 408 isn't easy, the 408 will give me more torque but they don't last as long. They wear faster in the cylinders with the shorter stroke at the bottom of the skirt. The 370 will last longer and could be there a long time, probably will go this way but its a huge debate.

Ah man that sucks! This is your daily driver right? From what I hear I'd avoid the 408 for longevity concerns. It'd be better in something that only saw a few thousand miles a year. So for you i figure the 370 would be best. I know in my head it'd suck to spend all that money on a short block and not gain anymore cubes.
Are you still running stock heads?

Well, my truck only sees 3k or less a year. I do a few 100 mile plus trips tho. I thought a 408 because of the torque and more low end power but the longetivity concerns bother me. A 370 would work but need to be cranked up more but would be better in the long run. Yea stock heads, not worried about that part tho. I'm not reusing any of it except the cam, rockers and valve springs.
What can you pick up a gen4 6.0 for? They seem to hold up really well up to about 20psi. I picked up a ly6 last week for 700 with bad cam bearings I plan on using for my turbo s10 project, itll be on 12psi daily and 17-18 for high boost.
A buddy has a low mileage motor from an 05, pretty nice shape. I could put pick it up and go thru it for prob 1500 total. If need to pull the heads and regap the rings, swap in new lifters and my cam. I could go that route but it's a real toss up. It only needs to do 12psi on occasion so I dunno what to do.
Oh I thought this truck was driven a lot more than that. For only 3k miles a year I'd definitely go with the 408. But if you can upgrade a cheap 6.0 then that seems like a much cheaper route.
Although the LY6 and L96 both come with square port heads so would the blower be able to fit those?

Been looking and it would be an 04 -06 6.0 If I went that route. Those have stronger rods by far and I can get one of those under 2k.
Its a giant debate, do i pop a used motor in and just let it alone.... or just do a motor and be done with it. Its a big difference in cash but to go thru changing it and finding a decent used one that i know nothing about...hmmm. A good low milage used one is between 2 and 2500, thats 60-80k. To put a new short block 370 or 408 in it with the trick flow heads i said about and use my cam i'm right at 7k. The question will be tho how long will it take to get it. I'm going nuts not knowing what to do. Either way will work with my 2300 and will do the current boost i want. 12 psi will work on a strong rod 6.0 from 04-06.
Could also do a forged short block and use my stock heads to save some cash, would take my 7k to 5 k and i could do heads later....this sucks..lol

just me but with boost does head flow make that much difference in performance at YOUR current level ?
Sounds like a used 6.0 is the way to go. You'll have to tear it open to open up the ring gaps anyway so you can always add ARP studs and rod bolts. Then if you're feeling saucy enough you can put the Trickflow heads on that.
