how many lb/hour would be necessary for an ls6 with a 4 inch stroke and .008 bore? should be around 10.5 compression. 220/220 cam .550 lift

The injector size is related to how much horse power you are going to generate.
Figure 450 HP.
.5 X 450 = 225.
It would take 225 lbs of fuel per hour to produce 450 HP.
You have 8 injectors; each injector would have to deliver 28 lbs of fuel.
You don't want the injectors to go static (on full time) so figure 80% on and 20% off.
28 divided by .8 = 35.
You would need 35 lb injectors.
