346 N/A Injector Size??

346 LS1
238 242 @ 108lsa
241 CNC ported, 0.60" decked heads
11.27:1 CR
Lunati Dual Valve Springs
Morel "Street" Tie Bar Lifters
Eagle steel rods
Mahle -4cc pistons (wrong choice.. I know.. )
Edelbrock Super Victor Manifold
Edelbrock 4-Barrel Throttle Body

Wanting to spin it to 7200

I need to know what size injectors. But all calculators I come across need a HP figure, well I don't really know that either...

Fuel will be one of two choices

A) Pump 98 octane
B) E95 race fuel

Obviously injector sizing will vary depending on the fuel type. Can you give injector sizing for both fuels?

Thanks!!

if you can make 1.5hp/cid which is not unreasonable figure 520 more like 550 hard to say with out knowing what your heads flow. At 550 apx hp I would go with 42lbs injectors e85 25%-30% larger
