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.

change of plans
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.
