If you're looking for 600+ rwhp, then yes it will be suitable. However there's MANY great manifolds out there for half that price.

Don't get me wrong, it's a very nice piece. I just couldn't justify spending $1500 unless I had no other way to get power.

Logan is a fantastic manifold, you however dont need it. All you need to do is buy a PI intake and that will take you as far as you need to go with the car...

he Logan Motorsports 4.6 2V intake manifold was designed for those 2V performance enthusiasts that want a high horsepower, high rpm edge, without the compromises. The stock intake manifold becomes a serious restriction at higher horsepower levels, and this is clearly evidenced by a 2V's traditional lack of rpm range. Even when coupled with the largest off the self cams available, ported heads, headers, etc; 2V's are generally out of breath by 6300-6500 rpm. This is completely unacceptable for a serious performance engine in this day and age. Now you can have 4V rivaling rpm range on your street car without sacrificing low-rpm performance. Independant testing has show over 60 horsepower on heavily modified combinations, with huge powerbands.

It also works extremely well on more mild naturally aspirated combinations. For example the following graph is of a 281ci combination with 10.75:1 compression, Comp 270 cams, and Livernois Stage 1 heads. The car has long tube headers and full exhaust, and obviously our new manifold. This is a very mild combination that idles at 800 rpm and has excellent driveability. It is also inexpensive and does not include any special parts. It produces incredible power however, with 321 rwhp and 309 lb-ft. This is extremely high for a combination such as this, and would be a good power number on an NA 4V. Also notice how long the power is carried, not only does it make a nice peak number but it stays near that number for a very long time.

PI intakes are supporting well over 600whp via turbochargers so if you don't need more than that don't waste your money. Ditch your NPI intake and swap to a PI with a metal coolant crossover. A full PI swap would benefit you greatly honestly and cost under half of what the logan would.
