Flame arrestors for Chris Craft 427 300hp engines

[Maurice]

I would like to replace the flame arrestors on these engines - 427 300 hp on a 1973 Hatteras FBDC.
Suggestions?

Jegs has a selection. I put a new Holley unit on my 327F along with a new Edelbrock carb.

Same. Holley Arrestors from Jegs atop new Edelbrock 1409 carburetors. Whole set up works great!
