Before I had vortec heads I always said my year was a 1979 el camino for the motor. The plugs will fit but the special heat ranges the plugs have are different. So just use a 1979 el camino. That was the last year for the 350

is just a 350 so what is the gap?

.45 for all 350 for all with HEI distributor. I use # 1 rapid fires from AC Delco. R45ts or R43ts were the original AC Delco plug.
