Nicson Engineering

I have a Nickson marine timing cover/ motor mount on a 392 Chrysler motor as Tubman mentioned.
from an old race boat. Also 6 Nickson air cleaners or spark arrestors. No through bolts to the carbs.
A pinch bolt type retaining system. Also 6 plastic debris shields on the Stromberg carbs. These carb
covers are the only ones I have ever seen. I have a photo of the boat and motor with the covers in place from
approximately 1961, surmised from the tow car in the photo
