The 90 is very likely the same as the 89.
this from my 90 Helms manual
lift
Intake 0.2750 + - .002
Exhaust 0.2856 +- .002
Journal Diameter 1.8682 - 1.8692

no duration and timing is given.

I do not believe the cam specs are identical throughout the TPI build.

If I recall, Car Craft listed all the specs, w/ the 1989 cams being the "most aggressive" of the tuned port cams...

Wish I knew where that chart was...

GM used a different cam in 88-89 than 87 Cam was again changed in 1990 when motor went to speed density. According to 3rd Gen site specs for 88-89 cam are 207/213 Duration at .05 .415/.430 @1.5 lift and .443/.459 @1.6 lift listed. Lobe seperation listed at 117degree Part number for cam from 3rd Gen site matches my GM Y-body parts book. Hope this helps.
