Emilio ran a 6-speed and a 4.30 all year with his NA setup, I think he's going to a 6-speed with 3.9s next year. bellwilliam ran a 5-speed and 4.30s all year, just switched recently to a 6-speed and 3.9s. For big power, 250+whp, I think the 3.909s are the ticket. 3.63s aren't necessary unless you are looking for 350++whp - when I have an OS Giken built it will be using my 3.909 setup.
