SBC TPI 383 ways to reduce torque

[nilak]

330Hp @~4700 is what I saw in the real dyno test with mild cam, and stock tpi. He is using large headers on all test. The 383 cammed, stock TPI manifold made 410hp constant between 4500 and 6000rpm. So between large tube intake runners and headers, the last seems be a better idea considering your DynoSim results.
