just like it says i have a 408 making 484/462 n/a and was going to put on a 200 wheel dry shot... do u think i will be maxing them out?

You would be close to max them out. I would go with 50# injectors. That should keep you safe.

My friends NA 427 42# were around 80%. I would re-think a wet shot (stand alone) or bigger injectors.

Based on my calculations, you will need a 50 lb/hr @ 3 bar injector running 4 bar fuel pressure. Check with FICINJECTORS <sponsor>, they have great prices and service. You woud be near 95% DC with the 42's.

I was running a 200 dry shot on a 408 that made 525rwhp on motor. With one walbro fuel pump, the regulator at the rails. I was maxing out 60# injectors. (90% duty cycle) at 7000 rpm. one walbro will really only feed 50# of injector.
Hope this helps
