I'm running stock springs with ti retainers to 8k and no float but I wouldn't go much higher than that and I don't suspect the springs will last all that long.

Cams are 236@.05 with .36" lift. Still makes power at 8k but the stock intake and TB have given up by that point.

I'm running a AEM series 2 that piggybacks off throttle, but is fully controlling cam\ignition\fuel.

Its hard to say how much I gained because it was a new motor with quite a bit of work done to match the rules for the class I race in. My peak power changed from 5.9k to 7k and stays flat until I shift at 8k but thats mostly due to running out of air from the intake man and tb.
