Is this on a stock short block? Or a stroker? What size heads do you have ?
I would probably use 30's and calibrate the mass air accordingly, that way you if you choose to run nitrous or change to a stroker you wont have to buy injectors again.

If you're getting your stuff ported, buy the 30's now. Dont waste your time and $$ buying the same part twice!

Go with the 30's and matching MAFM. You may also want to get a larger throttle body and egr spacer to take advantage of the entire combo.The TFS stage 2 cam probably wouldnt be a bad idea either. Also, if you dont have an adjustable FPR, get one, along with a fp gauge.

Last year i was running 30lb. injectors with a stock 302 and trick flow t.w. heads out of the box. And the car ran fine. Now i had my heads ported and i didn't have to change my injectors. I would deffinatly go with the 30's

i was thinking about upgrading my throttle body and spacer to a 75 mm and get a 80 mm maf cal for 30 lb, and i do have a FPR from Kirban. 30's is a wise decision, just so i don't have to buy new ones

The 24's will do fine for you if you maintain the 302 or 306ci displacement.

I have 30lb injectors on my 302/306 and they are to much and my setup is a bit more aggressive than yours.

Runs rich, and has hot start issues due to to much cranking fuel. I have a richer fuel curve...
