i know this subject is probably been talked about but i hear that my 82 280zx N/A has the "good head" and the crappy dished pistons and crappy intake? am i right? either way i hear there are different cams that went in to this same motor changing them every few years and from what i have heard is that the A series camshaft is the one to get? what kind of power increase am i looking at with this camshaft? any advice is appreciated

 

Dunno where you "heard" all this...

I'm pretty sure they didn't use the low compression "dished" pistons for the n/a after 77 or 78... you should have flat tops. There are various cams, but the A cam change is for the turbo.

Where are you reading this info?

Search our forums and Google for the L-Series engine and cam specs. I have those links at home, but I'm at work, and you should be able to find them online in about 30 seconds.

 

10 seconds actually...

so my stock 82 has flat top pistons? so my CR is 9:1ish? regardless what would be a cheap good power adder?

The only time I'd consider swaping in a stock cam is putting an "A" grind from a NA into a turbo head...
