Spark Plugs
I have a question on spark plugs. On a stock 350 SB with HEI what should be the gap on the plugs? Autolite AP26 Platinum states .045 that seems a little much? What do you think the gap should be? Thanks

.045 is great. In the olden days those HEI modules wanted .060.
You want enough "jump" to create hot firing. Too much gap could cause "flame out" conditions.
The module usually is the piece that demands what gap use use.
Until it gets into the "blown" alky applications, you need to stay in that .045 range.What if the "Hokey Pokey" is what it's really all about?

THANKS for the info!
The first model car I built was a 32 Ford roadster by Revell in the mid 50's.
How did you get hooked on cars?
