'89 360 LA valve spring/cam confusion

The roller cammed LA engine I just rebuilt was all LA and had nothing Magnum on it. LA heads, rocker gear and solid pushrods that were not oil through type. Not sure how yours does if you have a pre-magnum, LA engine. Can you post pictures of it. I'm curious to see.

The roller cam LA motors did have through-holes in the pushrods. At least the ones I've taken apart did. I think they still oiled through the head though because of the shaft rockers.

I'll get some this morning. The 89-91 369 truck motor was a LA block with hydraulic roller cam, oil through pushrods & magnum rockers ...

I think you mean 'magnum lifters,' not 'rockers.' I'm not sure how any LA motor could use magnum style rockers without a head swap.
