Fuel setup for 416 stroker?
Hello! Currently building out my engine to be a bit more powerful, and was wondering what would be the ideal fuel setup for it. I plan on keeping it NA for a while, but there’s a chance I might boost in the future. If there’s any other tweaks I should make to the list, also feel free to let me know. Here’s the mod list:
416 2008 C6 Z51 (automatic)
Eagle forged steel 4” stroke crank
Eagle forged 6.125 I-beam rods
SRP -5cc flat top pistons
TSP Bald Eagle boost cam (229/242 .600"/.600" 115 LSA)
3-bolt cam gear conversion
TSP 7.400 pushrods
TSP .660 springs + titanium retainers
CHE Trunnions
LS7 lifters
Melling High Volume oil pump
King racing rod & main bearings
ARP Rod bolts, head bolts, and cam bolts
2” LT headers
3” catless x pipe
What would be the ideal injector/pump setup for this? The area i live in only has 91 octane and 1 e85 gas station. I don’t have a way of dropping the fuel tank, so a boost-a-pump is tempting to me. Please let me know if any suggestions or questions, this is my first time ever trying to build an engine so im sure I missed some stuff!

You probably have enough now for dino fuels. Your injectors are the same size as LS7's. At some point LS3's got the same fuel pump as the Z06 Vettes too. You ought to ask the good folks over on the Z06/ZR1 page.

If you're planning to run e85 you're going to need bigger injectors most likely.
Here's my latest setup:
408ci forged stroker
twin turbos
dual pump Fore w external reg/ return.
IDX 1300's
DSX flex fule kit
Most likely ditching e85 and running meth come spring.
Too difficult to access up here and not real stable to store 55gal long term when temps drop.

My Old set up (f body) had an NA LS7 441 (13:1) and used a boost a pump (110 at track)
If you're going to be driving yours alot I'd tune off 91 since that's the fuel you have access to for street driving.
Maybe can use octane boost? for more aggressive tune? That idk.
Now I have a stock LS2 with base supercharger kit and has a boost a pump.
I don't see anything wrong with them but plenty will disagree and both the cars I've had one on were not driven a whole lot, maybe 3000 miles a year so fwiw

Fuel (octane rating), is all about the amount of compression the motor is making, so you don't have detonation problems in the cylinders.
Also to point out, NA the idea is to bump the compression up to make more HP, while with super charger, you drop the compression and let the SC boost increase the compression instead.
As for how and where you want to make power, that is all about stroke verse piston diameter to each other. Truck motors to make more torque down low, use narrow diamiter pistons and longer stroke, while motors that are going to be used for high rpm power that will rev up quicker, wider pistons then stroke distance isntead.
And if we are talking strip time, the biggest thing to make the car faster, is the torque converter itself. hence not only inital stall, but how it shifts between gears with the motor is bolted to.
