Aluminum BBC - Spark Plugs

Ben Kallies · 07-30-2013, 08:56 AM

I'm looking for spark plug recommendations on a 427 BBC street/strip motor with GMPP aluminum heads, 10:1 compression, .570 lift flat tappet cam. Using a mixture of premium and race gas. I'm hoping for actual part numbers, not just a brand preference. Of particular interest is the heat range suggested, as well as whether I need a .460 or .750" reach. Thank you in advance.
