You gotta love the fact that you have the same engine as a F-body.. That should be a TPI in which case..

305 G92 5spd / 350 AT 10111773* .413 .428 202 207 114.5 (116/-116)

I will say that the LT4 HOT cam is a lot of fun in an L98 from past experience but I would choose your combo of parts carefully instead of just going with an off the shelf cam.

I am running a cam from Lingenfelter Performance Engineering: Duration@.050 219/219
Lift w/1.6 Rockers 560/560
c/l 112

This thing idles decently and makes enough vacuum to power the brakes.
