    Hello Dave, Im hoping you can help me out. Ive been lurking here for some time and deciced to pm you. I have a holley 750 dp that is driving me nuts. I cannot get the secondary stumble out. Quick rundown its a 74 nova drag only car i bought turn key. 355 sb unknown cam specs, timing locked down at 38 deg. It is super responsive on the primary but has a stumble on bringing the secondaries in quick off idle If I hold it a 2k rpm it takes it no problem. 32 squirter in the front drilled on in the back. hollow screws. I stepped up the rear jets 3 sizes and it helped a tad but im worried now that in the heat this summer its going be too fat.I have an assortment of cams so thats the next step.. If I mash it open and manually push the sec. acc pump it takes it perfect. Hoping you can help me as im at my wits end here. Thanks so much for your time. David Drummond
