timing question

[dragstang86]

Im still working and tuning the 90 lx i bought trying to get it to its full potential. What kind of ignition timing should i be running? And what should i be shifting at with the 3500 stall c-4, 373's and an E-cam and 265 hoosier quick times? I think i was over reving it quite a bit when i made my only pass of a 13.70 @ 101 which i was a bit disappointed with. I also only had a 2.13 60ft. I figure the 60ft should at least be a 1.8 with this car. Between that and over reving it do you think 13.1's are possible? Im also adding an electric fan and water pump soon.

9:1 compression
gt-40 p heads
1.6 roller rockers
E-cam
Cobra intake
70mm throttle body
Msd ignition
and all the rest of the bolt ons

thanks for your help,
bryan
