upgrade injectors for ls1?

I'm looking for an idea on upgrade injectors and fuel pump for my 5.7 ls1 with a 218/224 114 cam and heads done.

thinking #36 injectors and a walbro fuel pump, what size pump would work well with these?

thanks in advance.

grab the racetronix pnp 255 pump with harness or the new aeromotive unit that is drop in. grab 36# injectors would be fine.

We have 35# and 39# injectors available.

The 35's will give enough fuel for around 550hp at the stock base fuel pressure (58psi)

The 39's should cover another 75-100hp over that.
