Best head cam packages
A few questions here on heads cam etc. Much appreciated if someone can help.
1. What are the details of the Fast 90/90 intakes?
2. Which cam is usually recommended that does not change response from 1000-2000 rpm at all, but provides the best power gains?. In other words, best gain above 2000 rpm, but no compromise bertween 1000-2000 rpm, (if such a beast exists). I have 205 AFR heads and Kooks exhaust/headers already to go. I also plan to have the throttle body polished and the screen from the air flow sensor removed.
3. Apart from the above mods., what other relatively easy mods are there for more horsepower/torque without changing response from 1000-2000 rpm, excluding forced induction and nitrous.
4. I spotted a BBK inlet manifold where 15-20 hp gains are quoted, but someone from a preformance shop told me they had one fitted and the car ran rough between 1000-2000 rpm. Anyone have any experience with this or other aftermarket inlet manifolds??
Thanks heaps for any advice.
Thanks heaps.

Gears are usually recommended for people looking to restore lost power from cams. Increasing lift increases TQ. So a short duration XER cam would do the trick but as you increase size it moves the powerband up without exceptions. 224/228 XER is the cam you are looking for.
Low end mods to increase low rpm performance include LG headers and gears.
The FAST manifold shows no loss of power down low in RPM.
