Would like some recommendations on spark plugs for Gen 1 195 AFR eliminators. 383 SBC,pump gas,no nitrous,street driven,9.8:1 CR.

AFR says to use a 14mm x .750 plug and gives a AC-Delco FR3LS as a starting point.

What are you all using for my application?

Thank you
Lonnie

I used NGK FR4's IN MINE.

I have the older version comp 195's on my 406, and i've had great luck with the Autolite 3924.

I use autolite 3924 also. You can also used Bosch 7557 but they are all the same . Besure to apply anti-sieze to threads.

Ditto on the 3924's. I run the AR3924.

Thanks for all the replies! I went with a NGK 5155, the same as a FR4.

I use AC Delco R43XLS.
