Default 36 or 42 lb injectors?

OK so I'm at a stalemate of which to get and understand when the car gets tuned they'll adjust the injectors. I've used the calculator thats linked in the Sticky and it says something like 34 lbs for the injectors. But others are telling me to go 42 lbs to fullproof it for future. The block is stock actually brand new zero miles, I got a very good deal on the typhoon intake w/ 85mm throttle body and z06 maf. The cam I'm using is a 219/227 .607/.614 lsa 110. I'm a bit of a noob to all this so if there's any other info please ask away. I'm wanting a driver not a race car I may in the future add a small shot. I picked up a GN gas tank with a walbro in tank 255 pump

Any thoughts on this?

I contacted FIC corvetteinjectors.com and they can suggest what size injector you need. I am sure one of the fuel vendors can also help. They will need specs on your engine.

If you are even in doubt between two similarly sized injectors, it is usually a good choice to go with the larger.

36 or 42? 42.

42 or 50? 50.

50 or 60? 60.

60-100# injectors aren't really considered "big" injectors any more. The newer high-impedance injectors have shorter minimum pulse-widths which make them idle and cruise like stock.
