Maximising a 460

[Tonkin NZ]

Into SPF2828 I put a 460 crate engine from Ford Racing with 550hp. I would welcome your insight into what improvements I could make to build HP or torque.

I have a
Victor’ Jnr single plane intake manifold,
Holley 4150 Street/Strip 850cfm carb w. mechanical secondaries
K&N Filter
MSD 6AL Ignition, Blaster HVC II Coil, Black Super Conductor Leads

Just looking at ways to optimise the engine and would especially like to hear from any one running Webers on a 460.

Thanks for your input....
