ackbar, i dont wanna sound rude, but do you think those mph figures could be incorrect track mph? i mean we have 2 tracks here in s.a, one of the older tracks gives higher mph than the other, about 2-3 mph. That, or you car is light, and has about 12:1 compression
sorry, just a thought that bothers me.
Now on the subject, i put the e-cam in with ported heads in my car for daily work commuter, i think the e-cam is great for daily driving, and is smog legal, and fairly economical.
For a mostly track car, i would go with 1.6rr's and tfs1 cam, and it would still be streetable, but not somethin i would drive to work everyday........sadly, i only gained 2 mph with heads and cam, using stock intake, but i found out the stock springs are not revving, and cant hold the cam lift, so i ordered some better springs, i expect to pull out a 12.90 at 105 pretty easy after i can rev it high again, it went 13.0@ 103 as it is, 3100lb car 3.27 grs.
but a custom cam will give you best results, as mentioned above.
