    Does anyone have any info on complete package prices and hp results? I love the 308 and 328 style and affordability, but have always thought they were severely underpowered. If these upgrades prove reliable and practical we may have found the perfect starter Ferrari.

    $25K sounds right for the amount of work it looks like must go into it...but the hp number seem like a strech goal, that is an awful lot of air to move through those heads not to mension the intake and exhaust systems....you'd be talking about custom bigger tube step headers feeding a coupple very large or very loud mufflers on the exhaust side and a custom straight in 8 throttle body intake...and you'd still need to get the air through the heads, there just isn't much metal to grind away to open them up. 320-350 seems like a more reasonable expectation in street trim....maybe 348 heads could be used, or 355/360 heads, that could get you over 400. Still a very nice improvement.
