getting rid of charcoal canister

C130 Chief's point is well taken. The charcoal canister is one of those few emissions control items which really doesn't adversely impact performance / mileage.

"Few" is an exaggeration.

replace your gas cap with a vented cap from the years priour to fitment of such canisters.

except not, because A-bodies never had vented caps.
