Gap Setting 255ci

Hey Everyone. as you saw in previous pics, my PO spray painted the truck flat black, including the sticker showing spark plug gap settings, and the vacuum route diagram.

I know what the factory spec is for setting the gap on a 302... but what is it on the 255ci?

The plugs that came out were set between .32 and .37

The old flathead 255s were set at a .30...

Im going out on a limb and going to say .35 Anyone strongly disagree?

And I am sorry I have not posted any pics, but my personal comp recently passed away by means of my dog spilling an entire beer on it.

New one scheduled to arrive next week.

Mike
