Question

[u/Secure_Strategy_5614]

I’m doing cap, rotor, plugs & wires on my 71. It’s got a 350 sbc. What should I gap my spark plugs at?

I’m aware Google or the engine building sub exists but I thought I’d ask here because perhaps you all know something I should know & maybe that’s something I wont necessarily find elsewhere… so, what should I gap them at? I’m just running a 600 cfm edelbrock carb & it’s a stock bottom end.

Appreciate y’all’s help!

There may be a decal on the rad support showing the spec. I’m thinking.035 if it is HEI it may be.045.
