LT4 LT4 Factory Ratio of Rocker Arms...What Was It?

[RubyDropTop]

Does anyone know what the factory ratio was for the rocker arms on the LT4? Was it 1.6?

Thanks for any input.

Yes, I think so.
Adding the 1.6 ones gave me
an 11 rwhp boost.

yep 1.6's... they are unusual because they are self aligning rockers... they were made by Crane Cams

Thanks For The Info. -

Can I still order them from Crane Cams? Does anyone know?

You can order them from GMPP.
