You know who you are! So just wondering how much boost on a stock cam? If I invest in a fuel system and run E85. I'm talking maybe duel fuel on my Whip. 16 injectors How much boost is feasible with a stock cam. I realize that you don't bleed off boost like in a higher duration cam. A cam swap is so expensive since I won't do the labor may as well swap a 6.2. Am I wrong? Thanks gentlemen! Almost out of debt so...close to mod time in a few mo!

 

Do you have headers or stock manifolds?

 

Stock but I will likely do 1 7/8" SE headers and either their 3" duals with quieter mufflers or a 4" single with ory and dual 3" to single 4" merge before fueling.

 

does the whipple intake have a place to put injectors - you would need some way to drive and control them? part of swapping the cam is the larger fuel lobe to up the high pressure fuel pump.
i think a few companies are starting to come out with +30% and +60% DI injectors - i dont know how much they are compared to the LT4 stuff though.

 

The intake has bosses and the fueling company has the whole setup and will mod the manifold for the 8 additional injectors. Supposedly supports maybe 1400 at the crank without a need to upgrade the DI setup if I read it correctly. All the hardware and software with instructions and support. I wish on the cam, but I just don't want to go there because the price of a 6.2 isn't that much more it seems. I would cam a 6.2 of course before installing one.

 

Dam, the newer trucks are so complicated to make big power it seems...

 

Totally agree on that one! I'd give anything if I had bought a pre 14. Box stock they run their *** off but modding is a big pain! So expensive.

 

But isn't the fuel system your talking about more than a cam swap?

I just think your trying to spend all this time going around a cam swap. When all roads lead back to you doing a cam swap. If you didn't removed the heads. It really wouldn't be that bad to do a cam swap on these newer engines. For the numbers your going to shoot for. I would think you'll be back right back to doing a cam swap.

 

Pmoore4321 has some video's on the auxiliary fuel system for his L83. The only difference is he already swapped a LT1 cam into it before he decided to supercharge it. But that cam doesn't come with a bigger fuel lobe.
