@ShortyMatt, Is 100% correct. As my truck was sitting in my driveway with bent pushrods & collapsed lifters I started joining Truck forums and reading about known issues on trucks variants. So I started buying more and more upgrades. They dropped into a few buckets. Induction, Cooling, Fuel, drivetrain, driveline etc. OnallCylinders was very helpful for topics when and where things get weak or run out.  For example Fuel tends to run out around 600-650. You'll need injectors, low side and high side pumps.  I knew I would eventually need them so I got them lol.

 

Missing the Gasket was just me not realizing and being excited that I now have a 7.0 vs 6.2 block. Honestly TSP should have recommended or shipped them with the block. 

 

@truckguy82 Yeah LT1's L86's are mostly identical however, any variant needs to have upgraded internals when going under extreme boost. Anybody boosting their block needs to think about upgrading rods, pistons and possibly crank. It will be the monster under your bead every day that one day it'll climb out and bite you. Also, the trucks weigh a lot more :), the truck is always going to have to work harder. Which makes a huge difference. 

 

Take my engine for example. On a dyno it will make 1200 HP easy. Put that engine into my truck and it will only put down 900 Wheel. Now put my engine into a corvette. It will put down 1100+ Wheel power NO PROBLEM. 

 

Okay same thought. Take a stock internal 6.2L Boosted block 700-800 Wheel engine from a corvette and put it into my truck. Tune it to 800 Wheel and you're going to start breaking things. As a reigning Forum champion you should already know this....

 

@ROB_IS_KING I would recommend James any day. He's is a trusted professional with ample experience.

I did forget completely forget about drivetrain loss, great point!

 

rough calculations through various dynos.

vette’s are losing about 13% to drivetrain

our trucks about 22%, and thats in rwd, no idea in awd.

 

700whp = 900-925hp crank in our trucks

800-825hp crank in the vette

 

Although it should still be able to take that no problem, it is definitely more possible it was not their fault.

Man, forgot to update. Truck is running great. Almost through the new engine break-in period. Even with low boost right now this thing pulls like a rocket ship.

Have you done awd or 4wd launch yet?

Still breaking in the new 427. Have to keep it mild for now. Once the piston rings are broken in it’ll be time to raise hell. I’ll put up a few videos tomorrow. I’m going to try and put  another couple hundred Miles on it. 
 

I will say even under 4K rpm on AWD it sticks like glue and will put a smile on your face. 2wd has been sketchy at best. The tires act like they’re on ice.

Very nice build bud. Sounds badass. Cam sounds huge for a turbo build

It's actually a pretty mild cam. Texas Speed and Performance SV cam. Specs are 223/227 @ .635 & 116 LSA. W/ 30% fuel lobe. It does shake the truck a little  at idle :).

Need to get yourself in one of those groups that goes out on the highway at night time and does roll racing with supercars. I’d do it just once and make a good video. Would be hilarious pulling on lambo’s

I love being a sleeper. Had a blue FRS try to pull off on me and I got a little into boot around 3500 rpms. Left him picking up his doors. You'd never know it until you hear the fighter jet taking off under the hood. 

 

I do need to figure out how to kill the drone the exhaust causes. Either I need to get a new one or It's the lack of tune.

Love your build dude.  It really came together.  Yeah the traction in 2wd forget it this time of year.  No f-ing way.  The wide summer tires I had on for all of 2 weeks before it started snowing helped tremendously but I'm back on the stock a/ts.  What are you doing for axle wrap?  The bottom plate is gonna be pointed at your oil pan with all that hp... hahah.  But seriously it's been a noticeable issue even with my current power level so I hope the caltrac bars I just got but haven't installed yet fix it.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
