Spark Plugs in Aluminum BBC heads
Trying to get a handle on the plugs folks are running or would recommend for after market aluminum head applications, both naturally aspirated and supercharged in a big block Chevrolet.
Thanks, Bob |
I know KAAMA is running aluminum heads but I don't know what plugs he's running. If I see him I'll ask.

I run NGK 5671A-8 plugs in Dart 325 pro 1 heads. The motor is naturally aspirated with high compression and solid roller cam.
|
I run NGK 5672A-9 or 10's, or Champion PN 791 pro stock plugs in natural 632 with dart 360 alum heads, solid roller cam.:cool:

Rapid fire #1 in Dart 320 heads. Non supercharged.
