Converting an L8T hood to a functional L5P intake (functional hood scoop).

Re: Hoods, Hood Scoops & Marketing...

 

Didn't the 'post MCE' GMT800 HDs (@ least the Chevs) have a higher profile hood than the LDs? Then near the end of the model run, the 1500s got the higher profile.

 

As we worked to retool for the GMT900 during GMT800 production, a future Silverado and Sierra were brought in for display. There were a couple of GM staffers from the States answering questions. I noticed that the GMC had quite a depression in the hood when compared to the current hoods @ the time. I asked 1 of the guys the reason for the 'rain catcher'. 'It's in case they want to add a hood scoop  (copying the Tacoma). I replied w/, "How about making tailgate cables that last?" That did not go over well. This was after the multi million recall which affected my truck @ the time. It suffered a broken cable when I dropped a snowmobile ramp on it. Thankfully I wasn't loading a sled as the tailgate didn't hit the bumper. As it was a black plastic hood scoop (non-functional?) was added to the Sierra HDs

 

Then you have the K2XX truck that differentiated the diesels from gassers w/ a functional hood scoop...

 

And now w/ the T1XX the braintrust says all HDs get the scoop...

 

TBH, if my truck didn't come with the non-functional hood scoop, it wouldn't have bothered me in the least.

A little heat gun massage may have us back in business. 

 

Stay tuned.

PITA Hemholtz resonator is the next hurdle. Accordian plenum is a touch small and out of place. Will need to make a custom tube and get rid of that massive thing.

It's only a 1.5 foot run. As ghetto as it sounds I might try a Fernco and 4" PVC run and if it works wrap it in carbon fiber tape or at least it will be a mock up for a spendy silicon pipe. I don't mind losing the big ugly Hemholtz. Will allow more intake noise. Just need to adapt (or delete) the PCV feed from the valve cover in that case.
