ratio is 1.5 ours is 1.7 iirc and pushrod offset is wrong. I have tried almost every production rocker out there. Just sayin.
they used to make a 1.65 rocker for ponchos

Thanks guys. Reason for asking this question is I was watching Gas Monkey Garage and they ruined a trans Am engine by using the wrong breakin oil. When the valve covers came off I saw what looked like our early 6.9 rockers with the bar between them. It looked like ours so I had to ask.
