unless u are planning on going with a massive cam in a stroker or a supercharger then its a waste of time and money.

the stock injectors will have enough flow for at least 250kw.

plus with bigger injectors u'll need a larger flow fuel pump and a chip to match. maybe even different fuel regulators.
cheers

just because the injectors are running out of fuel doen't mean that its there fault!
it could be ur fuel pump, regulators, maf sensor or oxygen sensor to name a few, that could cause it.

or they may require cleaning.

the std injectors used in the 215 and 220 5.7 hsv stroke motors where the same as the 304. so they will have enough flow for a "mild" 304!

The HSV stroker motors used bigger injectors and the more sporting 5 liters (groupA) all used 24lb rather than the stock 19lb, the stock ones would be struggling on a 5 liter with a very good (or open) exhaust

no way stock 304 injectors would be struggling with open exhaust i have a crane 276 cam in my car running stock injectors and i can tell u they do not struggle and they are only running 85%injector duty cycle so there is some more lefrt in them still.if u wanna glaze your bores and stuff your rings go ahead and put those massive injectors in
