What plug
Which spark plug should I use
I have a 86 TA with Edelbrock alu heads and am running
Wit AC Delco FR3LS plugs gaped at .035"

Does this sound good or should I change something?
Thanks

Edelbrock heads call for a Champion RC12YC spark plug.. In AC Delco land, that is a FR3LS (middle heat range, 1 being coldest, 5 being hottest).. You should be okay with that plug...
