stock is 65/66 i believe. i stepped up to 80 lbs. i believe they are early 454 truck injs. search you will find part #'s. i heard they are better units than 90 lbs? available rebult at cost savings. if you are planning mild mods just fiddle with the fuel pressure. i am at 19 lbs now on 80 inj's and running rich at idle. at 14 lbs FP was lean WOT. large injectors will mess up your tune big time. plan on burning some chips.
