I have a 5.7 350 TBI and I bought a Holly Throttle body and Holly Intake. I am running headers with no cat's thru flowmaster 40 series. Can I put the TB and Intake on without having a chip or cam? part # 300-66 & 502-6 from Holly. any help is great, i have these in my closet and really want to use them.
