i have swaped both on different engines. the iron one was 45 lbs, the aluminum one was 17 lbs. however, i hear that the edelbrock intakes lose a good bit of torque over a factory iron one.look at the goodwrench engine build up on chevy high performance magazines site. it gained 10+ hp and lost the same in tq. if your only swaping an intake, i would go with a non-egr factory iron or aluminum one.
