Whats the biggest cams for the 4AG?

I read somewhere that 260 is the max for the stock ecu. Wilder cams seem to work also, but their vacuum around idle is very low. This could sometimes cause idleproblems (who cares, just blip that throttle at stoplights) and, more seriously, lean conditions in the first moments of off idle acceleration. This could cause short bursts of detonation.

Also remember that camflow is not only determined by duration and lift. The lobeprofile is what's really important aka the area under the duration vs lift curve. This differs significantly between brands and is the reason why on cam can work better then another even though they seem to have exactly the same specs.
