u should always upgrade stock pump but if there is nothing wrong with ur stock pump dont replace it....are you having any power adder?????if not and just motor with that setup i would run 36# injectors..

Im sure you could get by with 30# injectors but I would go with 36/37# injectors. That leave you more room for when you need it!

I just did le2 heads/cam swap and put it on the dyno, car falls on its face at 4500rpm's. Fuel pump losing fuel pressure bad! So I'm getting a racetronix fuel pump hoping this solves any and all problems! haha.

Yea you should get the Racetronix Fuel Pump Kit and some 30lb. Injectors will work fine with that setup. You can run more injector if you wish and it wont hurt anything but the stockers are no good.

the motor is actually a golen 350 lt1 with the comp cc305 cam and stock ported heads 175cc head with 2.055 1.55 valves. Would my stock 24Lbs support this setup or will i need injectors or could i bump up pressure on the stock injectors? the motor is n/a with a stock 48mm throttle body and 1 5/8 shorties. I dont have a big goal id be happy with 340rwhp

24s are going to be a bit small.

30 or 36# injectors with a stock pump and regulator should be just fine.
If the pump is old or you suspect that it will not produce enough pressure at high RPM
replace it with a Racetronix 255lph kit. Inexpensive and just as easy to install as a stock replacement.

Remember to have the tune updated for your H/C and injectors.
You should no problem at all hitting 340 ... Even with shorties and a 48mm.

I'm getting by with 30's no problem and our setups are pretty similar.
