63lb Injectors and a Retune
MMR can wet sleeve the block to get you to 5.8 liters with the stock crank. The 2013 Shelby GT500 block is bored out to accommodate the larger bore, but the bore uses a Plasma Transferred Wire Arc (PTWA) cylinder liner coating instead of a metal sleeve. This is the same technology Ford used in the aluminum 11-12 GT500 blocks and no one seems able to duplicate it. Neither option would be a cheap way to pick up 20 cubic inches.
I still don't believe it...lol
I know a guy that got an aluminum block (DSS racing) bored out and sleeved to a 6.0 and it cost him 10K but never heard of anyone taking a cast iron block out to 5.8
GT500 is an aluminum block!

The 2007 to 2010 GT500s had iron blocks. In 2011, they went to aluminum blocks. Check out the MMR351R on MMR's website if you don't believe they do this with iron blocks. Check post 7 on this thread for a pic of the sleeved iron block.

So when did they come out with that?
Bingo! Hence my question on 5.8... I've not seen anyone add more stroke for the 5.8L only 6.0 and above. 5.8 guys usually go bore first then 6.0-6.2 they add more stroke. Which is why I asked as 99% of the people seem to keep the stock 5.4 as it can still make gobs of power
I really can't imagine stroking this motor. The bore is already small compared to the stroke. I would think idle quality would be out the window to. Probably couldn't spin her more than 6k either. Just my thoughts. For the money involved I would swap everything for the 4v running 20+ lbs of boost.
I don't see this happening anytime soon. She's burning 6.1 lbs of fuel per minute at WOT which happens to be the exact same fuel burn as a Roush charger on 10 psi. Mike and I were both very impressed with the burn rates and efficiency. Boost crept up to 14psi a few times and I turned white as a sheet. But he reassured me with the fuel burn rates. It's not taking near as much energy to operate the Whipple as it would the Roush therefore the power is going to the wheels and not wasted turning the blower. The crank is experiencing the same forces and stresses that it would with a Heaton running 10psi. My volumetric efficiency was 168% and cylinder pressure was between 1700-1800psi, all with boost temps 86-90degrees. (Can't help but laugh at the Heatons)
She was rocking to say the least. Looking forward to getting back on the track with fresh plugs and my new TPS sensor installed.
