I have this Lunati cam: Lunati Voodoo Cam and Lifter Kits 10230704LK I'm hoping someone much smarter than me can help me with valve clearance calculations based on its lift and duration. Its for a 383 0.040" over with flat top pistons sitting 0.015" down hole at TDC. I don't know enough about cam rotation to know if I will have enough clearance. I don't have the pistons yet so before I buy them, I need to know if they'll work first. The heads are Edelbrock E-Street 5090.
