I'm putting a new set of plugs and wires on my fastback - modified 302 with a mild cam, headers, highrise intake, Holly 650 double pumper...
I was thinking .40, is that too much? I'm replacing the plugs with autolite 45s, which is what I pulled out of there (I have no idea how old they were) I have a Mallory Unilite breakerless distributor, 8mm silicone plug wires and MSD Blaster2 coil.
Thanks,
Troy
