Y'all need to watch some Richard Holdener videos on YT. He has many intake manifold shootout vids and you'd be surprised just how good the stock manifolds are. Dyno is one thing. Real life is another.

Very nice what are your thoughts?

 

I got one on the work bench at home that I ported the snout myself to work with a Zl1 throttle.  I just haven't had time to install it yet.

contrary to what all the know it alls with stock trucks above say it performs about the same as the l86 manifold from what i can tell on the butt dyno the only noticeable difference is the vacuum it pulls on the boost gauge. Truck still fries tires through 3rd gear

l86 87mm. wanted to go with the lt5 but gwatney said porting it wasnt a good idea with boost because the remaining material was so thin

10-4 that was going to be my next question.  When I was porting mine I had to get rid of the stock O-ring.  I'm just going to silicone to ICT adapter to the snout of the intake.

thatll work my man thats what gwatney reccomends you do if you go to a larger tb i know of a guy with the lt2 manifold with a 103 mm tb and a 200 shot of nitrous so they must be able to withstand some torture

Yeah except nitrous doesnt pressurize the manifold or the throttle body, unless there’s a backfire.

ah i see im not really familiar with nitrous but i know plenty of people dont like using plastic manifolds with it while others have no issue at all using them

What bolts did you use to bolt you LT2 manifold.  I never installed mine,  then I spun some rod bearings.  So I pulled the motor myself and sent it off to the machine shop.  Now it's got forged daimond pistons 👍.  Since I got it torn apart I'm going to go ahead and install my LT2 manifold.  

 

BUT

 

I though our L86 bolts are to short so I went to buy LT1 intake manifold bolts and they want 23$ a piece at the stealership.  At 10 bolts that's more than I paid for the intake.🤬

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      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.
