Purple Vs Lunati Voodoo

FWIW the Voodoo 256/262 is working fantastic in the car in my sig. The engine has more torque than stock off idle and starts to really pull hard around 2600 RPM. I'm glad I chose this cam as I know that anything bigger would just make it even more sluggish on takeoff with the stock converter and rear. Since you have 3.55s and a stall converter I'd say go with the Voodoo 262/268. That cam could definitely use some better heads and more compression though, if you decide to upgrade more in the future.
