Dave plugs look good! and gears 4.56 This thing just has no balls I spent my high school drag racing days with a 70 chevelle SS396 really a 402 3.73 posi and that thing would tear the skin off your face! I was hoping this 390 would run close to it but it's a turd! I away thought FE engines liked high compression 180-190 range?
Atlas went down that road too! 3rd dist I have had in it, at this moment there is a mallory unilite mechanical advance,That is smooth as anything out there.But thanks you guy's keep them coming I hope someone can help or this thing will be on E-BAY soon!
