I have rebuilt 5.0 with 75mm throttle with C&L ass air flow meter,stock ported heads 1.90/1.60,ported stock intake,lunatti cam. I would like to put larger injectors, but don't know how big i can go without making other upgrades. I am not past making other upgrades, just need some direction. Thanx for any input.

It depends on what your motor is putting out for horse power.
19lb injectors will handle up to 304 hp
24lb injectors will handle up to 384 hp
30lb injectors will handle up to 480 hp

I have a C&L MAF with my GT-40 Ford Racing Crate Motor rated at 345hp.
C&L told me run the 24lb injectors with my set up. Just buy the 24lb sample tube for your MAF and your good to go. They said running the 30's would result in poor low and mid-range drivability and torque, and even decrease horse power.
If I wanted to run 30's, as many people do for future upgrades, I would need a dyno tune and chip. Call C&L , they are very helpful

do you have any times with your stock ported heads and intake? i kind of want to do that and get an e cam, or find some gt-40 or 40p heads and port those.
