Spark plug recommendations
« on: December 13, 2021, 05:55:45 pm »
Just got my 454 rebuilt.
Went from flat tappet cam to hydraulic roller. And went from peanut heads to 702 heads.
So my old plugs won't work. Looking for recommendations on what plugs to run. Motor is in a 21 foot open bow.
Thanks in advance

Probably (AC) R44 or the heat range of your choice.

Curious how the closed chamber heads run compared to the peanut ports?! be sure to let us know.

so.....what are doing with the old heads?

I will let you know.
I don't have specs but the 702's got a little work done to them. Bigger valves than came stock in 702 at the least. I just handed them over to the builder. Don't know if he will reuse them or not
