I don't think your cam is a 290/290 at .50 with a .447 lift. That sounds like a stock eliminator cam LOL it's probably a 290 advertised, which is still a healthy cam.
What heads are you running?

Ive personally raced a 350z or two in my 89 L98. i would pull hard on him thru first and then they would get within a fendor or so and pretty much stay there before i shut down. (50-60) Light to light i would beat em, and on the freeway im sure they would walk me.
You arent running the LTR setup (and my car was pretty stock excluding free mods and full exhaust) so i would say you wont have much of a problem with these cars.

Comp cam Lift .447/.447 Duration 290/290 Duration is .050
Even if that duration is advertised it still seems high for that lift.

I don't think the duration numbers you are giving are at .050 lift. I think it is total duration. 290 duration at .050 (what is typically advertised) would be top fuel style. What heads are these "stockers". Do you have casting numbers?
Normally a cam with .447 (assuming 1.5 RR's) and a 114LSA will have around 215 or 200 duration at .050.

Is that a Crane "Blueprint" cam? If so it has 222/222 dur @.050 w/ .447/.447, it's an old *** design from a factory hi-po 327ci engine.
I don't know how well that will run in some smogger motor w/ low compression and crap heads, it's kinda an outdated cam. You're probably only pushing around 300hp max, safer bet might be 275.... Should be a close run w/ the 350z, I think the track model has 300hp as well, over the 287hp in the standard models or whatever... {Edit - 2006 models all have 300hp if they're a manual, 287hp for autos according to a page from a quick google search}
Practice your launches and make sure you don't spin too badly out of the hole and maybe you can take him. Hard to say how well yours will run.

What heads are you running. Which "stock" heads do you have. GM produced hundreds of "stock" heads over the years. MorTec, Inc. Home Page
