It’s Nelson racing engines the company I’ve been talking to. But yes there is the option to upgrade parts to the truck engine to reach to 1000 hp and the option to swap to a LT4 with some upgrades . I was just trying to make everything a less hassle from what it is as much as I could in already built ready engine & tran system. So am still looking for good options

I disagree. Money is clearly not a barrier, so the sky is literally the limit. You guys are thinking whats the most cost effective; he's thinking 1000 hp.    On that note, Holley's new Sky R

Exactly ^^^   I figured stand alone wasn't what he wanted to do, that is a whole 'nother can of worms

x2 what these guys said above!  Can only imagine what a blown 427 with a trans would cost from a catalog 😳

If you want to know how to make 1000hp the easiest, you should be on the c7 vette forums.

 

Unlikely you have the mechanical knowledge to do this if you were considering LS swapping thinking it was the easiest option. Pretty funny you just want to slap in 1500-2000hp to an oem chassis truck with what looks like no consideration for brakes or suspension. I don’t know if you understand what that much hp is like, especially in 5500lb pickup truck. It’s not a 1500hp viper that can already turn and stop above 1g.

 

For your own sake. I would just let a shop handle it.

 

if street driven, i’d first find out what the transfer case can hold, because 1000hp+ rwd pick up the street is going nowhere fast without a full drag setup.

 

Maximum safe power while retaining awd should be your target unless it’s a dedicated drag car which means you probably shouldn’t start with a k2xx to begin with.

Yeah then screw the LS7 noise. 

 

Do some more research first. 

Budget second.

Realize your goals actually are going to be out of your budget.

Research again.

Set your goals.

Budget.

Build.

Personally I'd go for the 632 with a Holley High Ram intake manifold, hooked up to a twin turbo set up from Armageddon... On E85.

 

So much POWAHH 😍

I actually have this build option with the engine with the transmission to go with 4L75E-R and drive system kit, I also got a custom drive shaft upgraded installed with upgraded rear. I know it has efi carb from what I saw but that manifold needs to change to low pro and have it face forward with the intake my aftermarket hood only gained 2 inch rise from the stock but I ain’t trying do mods to my hood to make the top side fit in the truck. Seems good all NA power but I bit heavy but since I have carbon fiber hood, fenders, and bedside it should do some type of reduction this kit seems good it’s just a project truck also so the whole NA power is a big thumbs up. And yea am new to this type of things but I do have a good idea of what I want from the engine and transmission 1000 seems good I obviously know if I go greater hp I need more and more upgrades but I have a lot of things already bought but if I don’t have to add power adders to get there seem great

I think it uses the carb for air, port injection for fuel? You could have a spacer/adapter made for any LS/LT intake manifold but plenum volume is going to be a big factor. That's why I was thinking holley hi-ram. Short runner design but you can also get aftermarket plenum tops (wilson manifolds etc.); or have one custom made for that matter. Short runner design will make it more drive able at low rpm too. 

 

You're right I think it is heavier by about 130 pounds (compared to the LT1/L86)

Hoonigan did a camaro with the 632, you should check it out; might give some insight and/or more ideas.

Yes I recently tuned my stoclk 5.3 to put out another 40 hp over factory power, and I am finding the stock brakes can barely handle this..

if you want a rocket ride, I would start out with something that doesnt weight in at 6000lbs

I suggest heading on over to performancetrucks.net and posting this there. They would be more suited for your needs, hell I am on there too. 

 

But I think you are overly fixated on the "HP number". It seems like you are diving in without learning how to swim first

I disagree. Money is clearly not a barrier, so the sky is literally the limit. You guys are thinking whats the most cost effective; he's thinking 1000 hp. 

 

On that note, Holley's new Sky Ram intake manifold on a 632 would make for great burn outs :lol:

That quote didn't even involve money. I said set a budget because that is what you need to do but I never said that it was OP's problem.

 

I think OP doesn't have any idea what he thinks he is getting himself into and I think he may just be trying to get 1000HP to tell all his buddies that he wants 1000HP. If he thinks he is going to daily drive something like that then lol

 I will be getting a LS 427 1500 to 2000 hp deciding witch package to go with and it comes with full engine and transmission everything from wires efi kit, wires.

Just screams, "I don't know what I'm doing"

Yeah but anybody that’s ever owned a highly modified fast car before is fixated on a lot more than HP.

My previous employer owns a highly modified 2010 ZL1 capable of 900 whp on race fuel. His brother, who was also an employer of mine.. owned a highly modified C6 Z06 capable of 570 NA whp. Neither know what brand of exhaust they have or the specs of the cam without looking at a spec sheet.

 

When you have money you tell people what you want, AND you get it.

Nope, It screams you're jealous OR your are assuming he's full of it and doesn't have the money to achieve his goals. In either case you responded incorrectly. He's looking for help, not judgement.

Your thoughts on OP are wrong and OP knows what he wants to get into and OP don’t have race buddy’s or need to tell them that when OP can get it and the truck is not a daily driver at all moves around about once a month I’ve been actually upgrading the truck for 2 yrs now and focused on other things for the truck not just HP. I never stated one thing I was trying to do or talked about my build list or what’s else the truck going to have or direction it’s going. Honestly in my shoes it’s just better for me to buy something ready cause I don’t have the time and Iam new to swap not new to performance parts and if I don’t have time why would I get into upgrade after upgrade after upgrade to build up the engine if I don’t have time now I won’t have the time later just to repeat to reach the same thing am trying to do now. Just looking for advice.

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      By bluev8 · Posted

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
