Cast Rocker arms
« on: September 15, 2010 - 08:27:41 PM »
I have a set of Cast Rocker arms that don't fit on my 360 heads, four of them line up with the push rod the other four are way off.  Am I missing something? Casting number are 3577692, 3577071 and 3577071.  I can't get a photo to load.

If I can't use them I'll probably look to unload them.

The rocker arms are right- and left-handed. You may have all the same side in your set. It requires 4 of each for one head.

With ductile iron rockers, I believe big block rockers are left & right. Regular small block are all straight so it doesn't matter how you arrange them.

Your rocker arms may be for OEM 340 6-pack T/A heads with factory offset/relocated intake pushrod holes.

Big block rockers:

"Regular" small block rockers:

340 T/A exhaust rockers would look like the other iron small block rockers and can be used on regular head intake and exhaust positions. The T/A intake rockers look the same, just at an angle.

I couldn't find pics of the actual 340-6 T/A rockers yet.

Here is a better pic of a Crane small block rocker for regular heads or T/A exhaust.
