the 42 SVO's are way too be big for that..did you tell him that they are just 42lb injectors or 42lb SVO injectors..because the 42lb SVO injectors are actually about 48.xx lb injectors because they are rated for 43 psi fuel pressure..and your truck is running 58 psi..that would make it run like **** for sure..just find some 30lb SVO red top injectors..because at 58 psi they are around a 35lb injectors and that should fit your mods perfectly

I went to dealership and borrowed a fuel press. gauge, I had 60psi idleing and if I blipped the throttle it would dip to 55psi. Jesse at w4me said it will probably dip to 30psi driving it. heres my fuel system; stock 99 intank pump goes to a vette filter/regulator,I basically plugged my lines off my stock intake into this filter/reg. My fuel rail is a single line off camaro.I am running this same setup on my 69 camaro ls1, with no problems. What do you guys think about this setup. Should I go to a 255lph pump and a diff regulator?
