what is the difference between SVO 30 Lb Fuel injectors Compaired to Fast 33lb Fuel injectors ? Cause i've been hearing that alot of people have been running these SVO's 30lb injectors for a little time in there 402 + cid engines ? is this good or not ? what would the DUty Cycle be for the FAST 33lb Fuel injectors i know they will be almost maxed out , but will they work ? OR will i take a Change in running the engine LEAN ?? not enough fuel ?

With your setup I would buy some 36 or 42 lb. injectors.

the SVO 30lbs when calibrated read around 36lbs/hour on the lsx motors.

This is correct. They are great injectors for the price you can get them through most Ford performance shops.

BTW, this needs to really be posted in the Fuel section.

so your saying the 30lb SVO injectors can handle a 402cid motor better then the FAST 33lb injectors

They will work better based on the SVO's reading 36lbs vs Fasts being 33lbs... But will they be able to keep up with the demands of the 402? I have no idea... dont have experience with that.

SVO 30# injectors because they will be acting as 36# injectors will handle more fuel than 33# injectors will. If it will be enough for your specific application is yet to be determined. That all will depend on your setup and fuel needs. If its gonna be more than 450 RWHP or so, I would bet that even the 36# injectors probably won't be enough (or if they will, their duty cycle will be almost maxed out). More than 450 RWHP and I would step up to some larger ones like some 42# SVO's and that should take care of you until you get to about 530 RWHP or so. This is to say nothing of needing a fuel pump to keep up with all of that, but that is all a bit far off from the original topic about different injectors.
