I have both a 3310 vac secondary and an 850 DP. Which would you recommend for the following? This is a street car.

69 GTX convertible
440 (10:1)
Edelbrock heads (out of the box)
CH4B intake
Hedmen headers
727 (2500 stall)
3.55 SG
I haven't picked the cam yet but leaning toward the Lunati 60303 (226/234 at .050 .494/.513 lift)
