Hot stock cam for 540 bbc

[Superstock100]

Hey fellas, i came up short on rpm and power for my pulling motor. Having to use exhaust manifolds the first cam we tried was a 262/266@050 114lsa installed straight up. Made about 750hp@6600.

Any reccomendations on what i should try to rev this thing 75-8000rpm?

15:1 540ci dart iron eagles 2.30/1.88 . Weiand dual plane intake .

Ideall… i would like too see 850hp @ 7500-+

Why the dual plane? Class rules?

Yes class rules. Dual plane intakes are a must. Porting allowed
