Should be In/Ex 294* @ lash point, In/Ex 202*/206* @ 0.050" tappet lift. Valve Lift In/Ex 0.403"/0.415" with 1.5:1 rockers. 115* lobe centerline.
Same cam used on IROC-Z Camaro part No. 14093643.
Hope this helps.

Just to confirm: This of course is identical to the 1985....but in '87 L98s it was a ROLLER cam...?

Yes its the same spec, but it is a roller.

88+ had slightly different profiles.
