Pewee Valley, Kentuckyy here! Inherited a decent condition 1983 El Camino. Currently has a 305 needing some work. Lower left side of engine has years of oil/fluids from leaks, valve cover gaskets leak. Looks great and is fun to drive! I've looked at a 350 or 383 swap, still researching the best fit. Also may just clean up the 305, add some headers, valve covers and poly gaskets and call it a day.
