    What size injectors??

    Hey guys. I'm running a 02 LS1 with a custom grind cam (598-599/223/113LSA), LS6 intake, P&P 241s, long tubes, and going to have either 3" or 3.5" exhaust. What size injectors should I run? Thanks.

    I would just search somewhere on the internet for "injector size calculator" and you'll find something.

    Thanks for the input. Will the 35s give me enough room for growth without changing the to larger units?

    36 lb. injectors will support 500 horsepower while not exceeding an 80% duty cycle in an N/A motor.

    Take a look at this calculator (bottom of the page): RC Fuel Injection

    That calculate is great. I guess I could pick up a couple sets so if ore is needed at tuning I could swap em out.
