The Perfect Spark
Hi Jon, I’m building my first engine, with AA 80mm pistons and cylinders, a Wolfs-burg West Okrasa kit, performance cam and stroker 69.5mm crank. Based on this setup, which spark plugs should I use? I don’t mind using non-Bosch plugs. Thank you.

Jose, assuming that the heads use a normal 14mm “short” plug, I would use either an NGK B5HS or B6HS. These plugs will work great on any engine operating under normal conditions. Of course Bosch still makes plugs for this, but they are made in Russia. No, I’m not kidding! I’ll let you ponder that decision.
It Just Wants to Stall
I have a good one for you. I have a bone stock 1960 36-horse engine with about 90k miles on…
