yes 4.085 bore on a ls3. Yeah I kinda wanted to try it out and see what it would do but didn’t work out ... I just order a cam from TS 251/263 kinda of a big cam but they told me should work good.. I also not sure what intake to get I been doing research and I’m leaning towards the Holley high ram intake (would work for me in the future since I’m planing on going boost). Honestly I think this stall is to big for my set up . Like I mention before a couple of people told me to get a smaller stall to catch all that torque that my stroker makes but I’m not so sure about it ...
Whats wrong with 4.085 bore?
I've ran mine upto 7500rpm with no problems, it now uses zero oil which is also new!
00pooterSS
Man feel way better dude I was beating mustangs/trucks 5.0 camaros other trucks etc lol the mustang owners got booty hurt lol some of them did tho. Getting beat by all motor truck 😂😂 I would tell them is a 6.0 heads and cam 😂😂
The truck been down maybe 8 months already I went to the track last December ran a best of 11.411@118mph full weight half tank. One week later my tranny took a ****.
Now the truck ready to come out with some new goodies! In the mean while I was researching trying to decide which set of heads I was going to use I was searching on this 4 set of heads.
PRCS 260cc
Frankenstein m311 heads 273cc
Greg good ls3 ported ones
Frankenstein ls3 stage 2 porting service
Well I end up doing the math and if I would of went with Greg good or Frankenstein stage 2 would be like around 2200 including the services and buying a set of 821 heads. Then a friend of mine With similar set up made 569 with some prcs 260 so I end up focusing on the m311 there’s not a lot of set ups NA or nitrous so yeah. but for my understanding a lot of boost guys have this heads since they come standard with 72cc and they work bad ***. so I decided to give them a try. Man they are beautiful quality. Anyways the new parts for my truck would be m311 heads (Milled them to .042) to get 65cc this guy Timothy Peterson from hyperfomance Xperts hook me up with the heads. Also recommend Me which set of lifter to use which I end up using the 2116 Johnson lifters I also bought nitrous express Holley high ram plate and I’m getting my Holley runners port match my heads Greg good is doing the millling and porting. I’m also going to get a 5” air intake hopefully she will breath more the plan is to get the 112mm nick williams TB in the future.
Also waiting on circle D to finish my stall I went with the same stall speed which is 3200 a lot of people keep telling me to go up on the speed but I mean I’m cutting a 1.611 60” almost 1.5 so I end up just refreshing the stall I’m also pulling the motor out and putting all new gaskets and see how she would do on a 200 shot of nitrous hoping for close to 600rwhp all motor and hope to get close to 850rwhp on nitrous will have result in 3 weeks or so my goal is enter the 9s full weight. Will be making a video on YouTube after some dyno result etc hope to get new track times as well. Stay safe my friend 🙏
Sounds good man, should roll out with the new parts.
As far as the stall I'd like to see a 4k stall in it, maybe higher like a 4400. 1.5/1.6 isn't horrible but my bolt on only 2000 SS did 1.6 60 ft times too.
I'd like to see a 1.4 or so out of a truck with that much motor in it. You're also using a short runner intake that favors upper rpm power.
MAKE SURE that the converter will hold the nitrous. Make sure you talk to Circle D about the power and power adders you plan to put through that converter and be honest, if you think you'll up the spray on it tell them

As far as the stall I'd like to see a 4k stall in it, but 1.5/1.6 is pretty good. Like to see a 1.4 or so out of a truck with that much motor in it. But a 3200 can still get it done, 4k stall should be a decent amount faster on the 60

well they spec me this stall for nitrous last year so I’m sure it will be doing the job I also want to go up to a 3600 but for now I’m going to stay with stall I got faith lol will see
I’m back!! 😂 well I been doing some research about 112mm throttle body but nothing! I seen most of the guys that gets one are boosted matched with the kong 2650 Well I pull the trigger and bought one for my n/a—— nitrous Silverado set up that thing is huge!!! My NW 102mm fits all the way inside the 112mm 😦 I had to port match my Holley high ram intake to match the 112mm adapter and it matches bad *** I just need to finish a little bit on top but everything else seems good! Here are some pics! I been waiting for my mechanic to finally finish assembling the motor but he be BS! Anyways hope to have result soon! I bee using a 5” air intake to let that sucker breath! Some people told me I don’t need the 112m is to big! is overkill blah blah blah! Will see tho hopefully I’m not making a big mistake! Lol for the fuel Im going to be using ONE ethanol R on my nitrous stand alone and mix of pump E and One R on my tank.. my goal is to push 600+ all motor and will be spraying 250 shot!!! Got a nitrous express plate/fogger system for Holley high ram hope to hit 850+ But my main goal is to run 10s all motor full size just a drag pack!!!! Previous personal was 11.4@118 now with new aftermarket heads port match high ram 112mm 5” air intake will see! Anyways will see winter season is coming as well 🚀🙏💪
I think I’m going to be the first Silverado with this heads/ 112mm TB NA/ Nitrous build will see how it goes 🙏🚀 like I said most of them use the heads and TB for boosted application!.
Finally got the motor back together Looks good with the solid motor mounts Atomic fabrication Looks good with the 112mm TB underdrive pulley. Trying out my new drag pack d6 forgestars beadlock in the back Waiting on my front tires to get here .
I’m also waiting on my oil catch can/reservoir set up going with a 12an lines set up I’m also waiting on my 5” pipe to get here I only got my MAF so far 👍I should get more pics next weekend like I said my main goal is to run a 10s pass will see 🤟🏻🚀👍🙏🙏
