I have Ford 30 pounders in mine. Its a 383 stroker with 220 heads, Superam base and top. Mild custom ground cam, 1.5 rolling rockers, and full headers. I just installed a Dewitts radiator because car would overheat on hot days with the 383. Oh i forgot. I got a custom burned chip from Fastchip.
I have found the same thing. At what point does everyone agree that 30# injectors are the way to go?
No one agrees, unfortunately. Heated battles over it sometimes. In my case, motor never goes above 6k rpm. 24's work well for me. If I was turning 7k, I don't know they would. Regardless, I have run the ford 24's since 1993 with no troubles. Quality injector at a fine price.
If your tuner said #24's go with them. I had #28's but my tuner said they would be maxed out and I should go with #30's. So that's what I went with, Ford #30's. The Lightning has #60's because the tuner for that said they would be better than the stock #40's. Both seem to run pretty well.

You said it was a 383 with a superram, but what else has changed, ie cam, ported heads, etc. If Alvin told you the 24's are fine, and he is going to tune it, then that is what I would use. If it turns out it needs bigger injectors, changing them and readjusting the tune is not that big of a deal.

according to this link I'd need a minimum of 35lb injectors if I had hoped to make 450HP.
The 24lb injectors are only good to 307HP, and I better be making more than that
the 30lb injector is good for 384HP and I am hoping for more like 425ish HP or so.
Is this tool not applicable?
Go to the bottom of the link above to see the calculator.
Don't believe everything you read. Ask your tuner!!!!! If the calculator you used was always correct do you think I could run high 10's and still run slightly rich at WOT? Real world experience has proven 24# SVO's are good for quite a bit more than the calculator may recommend.
This can be a very heated debatable subject. Use what your tuner prefers.
