Title: Spark plug question
Post by: SReist 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.

I've won a lot of races and putted around town with Autolite 124's.

Thanks to all. At least I'm on the right track. Steve
