Re: '87-'88 Stock Cam specs? (GRX)
All I have is specs on the '88 cam with 1.5:1 rockers:
Lift=.410"/.423" (int/exh),
Dur=211/219 deg @.050” (int/exh),
LSA=117deg.
the 85-86 cam:
Duration @ 0.050 202/206
Lift with 1.5 R 403/415
Lobe Seperation 114.5
Lift=.410"/.423" (int/exh),

I honestly don't think a stock 88 cam has that much duration. The 87 has different cam than a 88, same specs as the 85-86 but as a hydrualic roller cam (as oposed to hydraulic flat tappet)

Re: '87-'88 Stock Cam specs? (dgoodhue)
BTW On this page the lift numbers are listed http://www.corvetteactioncenter.com/....php?qstId=169
w/1.5 R these compute to a lift of .415/.430
On this f-body page http://www.f-body.org/tech/tech.htm#ThirdGen
The 88-89 f-body cam is listed as .415/.430 207/213 (@0.050) w/117 lobe seperation.
If I was a betting man, I would guess GM used the same cam for 88 and 89 F and Y bodies and since the lift numbes match up.

The numbers came from 65Z01, he stated that they come from his 88 Helm Manual. (if i remember his words correctly)

Its not a direct conversion remember, if you have a 202/202 flat tappet cam, its not the same as a 202/202 hydraulic roller.
