Thanks for the correct specs! Looks like I need to re-adjust my guesstimations! LOL!

I did consider HEI, but due to how clean the plugs are burning I didn't want to add extra spark that doesn't seem needed. It's hard to tell weather it would actually do any good or not. Plus I'm enjoying the fact I can run 89 in it. haha
