eddie 600 is a good choice as it gives some room to grow. I have a 1406 on my magnum headed 318 with a 208@.050, .506" lift roller cam, RPM air gap and headers. I had to change the step up springs to the pink or natural, jet the primary down to .095" jets and .073/.052 rods and the secondary down to .089 jets. that was tuning with an LM1.
