Best Spark Plugs for a 1970 454
Just rebuilt the engine and wondered what you all think are the best new sparks plugs to use (currently using Champion RV17YC plugs)
This is the original engine with the 1970 454 spec. i.e. 390 bhp and 10.25 compression ratio.
Regards
Paul

Use the Autolite 605. They have the tapered seat and a .7 reach and more importantly they have a 5/8 inch drive socket head which makes changing them much easier.
