So, thinking I won't be spraying this motor after what I seen...detonation.
Guessing I'm pulling some timing and/or using better gas.

BUT, gives reason for an upgrade.... thinking 408 time ?

Do the plugs show detonation? Plugs don’t lie.

Only did one hole... wasn't happy, buttoned back up...and doesn't help it's about 30-35*F

Plug looked fine (BR7's) but thinking about pulling timing and sticking some AC Delco's back in. Will take a better/closer look at this week since I'm over it now LOL.
