Default Re: Spark Plugs for 283 SS Motor

These engines have low compression ratios ,enormous camshafts , and probably oiling issues from the lowest tension rings and restricted induction systems !! Id go with AR75's as I've seen done !! Gotta go back to the 85b !! sorry if i hijacked your thread !!
