size of injectors

I am looking to buy accell injectors for my 5.7 tpi. How do you know or find out what size I should be using. I had thought that 24# was stock but I am not sure. I would look at the ones in the car, but of course the car is still in storage due to snow.

Please help so I can use my Z this summer!

i ordered a set from www.fiveomotorsport.com they're ford parts but they're 22 lbs at 43.5 psi. Only 200 bucks including shipping and they work great.

The formula to determine injector size is:

lbs/hr x 16 = horse power output


Trickster is correct. If you do any future mods and increase hp you will need this formula to determine what size injectors to upgrade to.
