Looking for new heads/cam - car details inside Hey guys
I'm currently itching for something to do on the car since I haven't done anything to it in a while and its fun for me.
anyway my current setup is
1976 Datsun 280z with:
2000 LS1 T56
224/224 .567" I/E on 114 LSA camshaft (with appropriate springs/pushrods)
FAST 90/90 intake/tb
sanderson 1 3/4" headers
2.5" exhaust off collectors to single 3" (no cat/res) bullet style magnaflow muffler (have electric cutout to install, 3")
Current best 1/4 mile is 11.77 @119 with a 1.77 60' on 235/60/15 MT Street ET drag radials (no room for bigger tires
)
Power output is 378 rwhp 367trq (400 was tire spin). I do shift around 6700-7k at the track but most of my driving is city/hwy.
My heads are currently stock 241 castings with the upgraded springs (918's? i *think*).
I have a whopping 3500 miles on the swap since its been in the car 2 yrs. Needless to say its a toy car, milage doesn't really matter but it needs to be drivable for me and my wife.
I'm thinking with the FAST intake and current cam that heads are the next power mod that should make it all work together and unlock some synergies of the mods I have. I'm now thinking of ditching the 224 cam for something since I'll be elbow's deep in the motor anyway.
I'm wondering if stock 243's heads are worth while since they flow a bit better and give a slight bump in compression. Or I could get them then mill them to decrease the Combustion Chambers to further bump the compression (I have 94 octane readily available here) but I'd keep it reasonable. Or the LS6 heads from TSP that they have and a cam like the Torquer V2.?
Another option that is popular for my small-ish cam are the 5.3L heads milled to 59cc chambers which gives the compression bump, again looking at TSP for those. If I did these heads can I even go to a larger cam?
Goals = sub 11.49 or so for the track so not huge there, the magical 400rwhp would be nice but driveability on the street is the most important, flatter torque curve to redline, I'm assuming that the flow is hurting me in the top end.
I've done some searching and what I've mentioned above come up time and again but I haven't been active on here in ages so I'm not sure if I'm missing something along the way...
Thoughts? Comments?

228-230 cam heads milled to 59 at least and a decent set of heads, let it be 243, afr, TFS, or pi...that should make a decent setup...
try a search there is a ton of builds with results...if you want a more track oriented setup look up my old threads
