Spark plug question
« on: January 01, 2021, 06:13:16 PM »
I need to find a replacement plug that closely matches the BF32 Autolite. I have narrowed it down to three choices. The NGK
AP6FS, NGK AP7FS or the Autolite AR33. The engine is a 428CJ block, 4.125 Scat crank and flat top Diamond pistons. Induction
is a BT 428CJ intake, Quick Fuel 780VS and Lunati .509 @260 solid cam and stock CJ heads. Thanks in advance, Steve

For higher compression stuff, I'll use an Autolite 124 or an AR 32/33.
