Default leaning out a 351

my friend has a 94 stang with a 351 in it. he has problems with engine leaning out at high rpms. he has a holley 830, victor jr intake, performer rpm heads, stock fuel pump, external fuel pump, torquer 2 cam, 1.7 rockers. He is not sure how to set his carb up. If anybody has ideas please respond thanks.

wait wait wait i gotta laugh at his setup.... edelbrock makes different lines of products for a reason, they are made to work with other components of the same line of products.

why does he have performer rpm heads but has a torquer 2 cam and then a victor jr intake?!?!?!!?!

anyways tell him to fatten up the jets on the secondaries a couple sizes and see where that puts him

nice help

man that set up is wack..you have a bigass 830 on a vic jr intake and low small heads.....I would say your feul pump or pump is the problem..that 830 is big..after checking fuel pressure. also check you filter and the screens in the bowls if they have'em..without changing jets try using a larger squirter in the rear barells to start
