The L99/LS3 are pushing more HP with straight manifold, off-the shelf (Vette) heads, filter, etc. So imagine when you slap on long tube headers, K&N filter, etc. You're adding 40-50 HP with about $1500 in mods.
And Camaro still has a Z-28 lurking...

They gained 34rwhp on a new 5.0 by adding a x pipe, catback exhaust, k&n drop in air filter and some tuning.
So no the 5.0 is not maxxed from Ford.
