Std 302 Rocker Ratio

[Andy Green]

Hi all,
I’m currently rebuilding my SBF 02 engine, 1974 vintage. I have the standard rockers, which I believe the ratio is 1.6:1 Can someone confirm that I’ve got my facts straight <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o></o>

That's correct, they are a 1.6 for both the intake and exhaust.

1.6 is the stock ratio and you can use 1.7 for more lift as long as you have the piston to valve clearance.
