So does this cam make enough vacuum to power the brakes??? Im building a 408 with the same compression ratio and LSA supercharger setup and was trying to figure out what cam to go with that will still be streetable and vacuum friendly……did you ever switch out the ghost cam for something else??

Still running this cam. No regrets. Couldn't ask for a better driver cam especially with a manual. Minimal chugging at low RPMs. Will easily turn 6th gear at 60mph at like 1300rpms.
Zero problems with vacuum and the brake booster in a C5 chassis. It has no overlap.

IIRC I had to go shorter for my combination. Cleanup pass on the heads and decked block.
7.385" I believe. It probably would have been fine with 7.400s but the preload was a little too much.
For ***** and grins I did spec out a more custom cam from Cam Motion last month giving them every detail about the car and combination. It is a very thorough questionnaire they ask for.
The cam they came back with was basically their largest street based blower cam they have I'm sure mostly factoring in the 408 cubes part of the combo. It is a monster. I'm a little hesitant to try it.
238/254 119+4
They also said the Pac Beehives would not be wise and to switch to their dual spring kit.

They didn't say anything and I can't imagine it would be a problem. These cams have little to no overlap. Worst case scenario, turn the idle up a little bit and I'm sure it would clear up.

Great Work, Mr. B! You are still my idol 
I would have guessed closer to 700 but I know you are conservative and will creep up on that number - easy peazy for the guts it has.
Upon the advice of Ron and other people WAY smarter than me I am ditching the SD tune and adding a card style MAF. Finding room is the hard part. 20# of Poo / 5# Bag. Mine has been down all winter but I'm making time to work on it. I also found a different / better? adapter plate for the cathedral - rectangular issue. It has been a S.O.B for Ron - hopefully, he'll have me back.
I also found a tiny vac leak where the AC hose hooks to the blower - that little hole could have caused a big problem. Dunno?
Keep up the always fine work. And using cool words like 'tutelage'. LOVE IT !!

Thanks Jumbo.
Somewhere in this thread I think I showed how I put an LS3 card style MAF in my intake using a 4 inch pre made tube.
I didn't keep it though because the 3 bar operating system wouldn't fully recognize it and work properly. So I ended up removing it and selling it.
Yeah, I could have went back to 1 bar operating system and ran the MAF but in my case the car drives so well that it wasn't worth the time and effort IMO.
P.S. I am thinking about making the switch to a Whipple 2.9 liter C6 rectangle port blower lol.

I don't know how I missed this. Apologize for the delay.
We loved out Gladiator but absolutely hated that POS 3.6 liter pentastar engine.
This one had the Max Tow Package as well. Most I ever towed with it was around 6500lbs and it pulls it great and handles well. With or without weight distribution.
Two biggest negatives, Gas mileage SUCKS even not towing. Gas Mileage MEGA SUCKS when towing especially an RV with all the drag.
The range while towing blows ***** at 7mpg. Also when towing the RV it would just stay at high rpms and when going cross country it is very annoying, I also have no doubts we would have eventually blown it up. That engine is known for blowing up even without towing lol.
So we ultimately decided to trade it off for something a little more comfortable for our towing needs without going back to big diesel 1 tons which we've had several of over the last 20 years.
While we miss the Gladiator, especially the wife, I am absolutely loving the low mileage 2017 Ford F150 Platinum 3.5 Ecoboost that we got (also has the 36 gallon tank).
If you have any other Gladiator questions, by all means fire away.
