Polished Aluminum Intake 96mm Typhoon New with fuel rails I bought this for my 408 stroker but I am going a different direction now, maybe carbed. This is for the ls1 engine that breathes well with heads and nice cam. This intake is the 3rd configuration in the description. 18 more horsepower than the Wiand or LS6 intake.

This unique new design features a larger plenum volume than stock or aftermarket manifolds, somewhat similar to the 2006 ZO6 manifold.This larger volume is particularly suited to big inch engines but extensive dyno testing on a stock LS1 also shows substantial gains, especially in the mid-rpm ranges.Tested primarily against a leading aluminum aftermarket manifold that is similar in design to the LS6, the Professional Products intake showed equal power on the top end with an additional 12 to 15 hp in the 3,000 to 4,000 rpm range. It was also tested against a factory LS6 and produced an additional 17.7 hp at 6,200 rpm on an engine dyno. The manifold is available in three different configurations with each of the three offered in either a polished or satin finish. The first configuration is designed for the LS1 and LS6 engine. It features an 85mm inlet opening and uses LS1 style throttle bodies. The second configuration is for LS2 engines and features a 96mm inlet opening and uses LS2 style throttle bodies. The third style fits LS1/LS6 engines and has the 96mm inlet opening. This manifold requires a 90mm throttle body but the fuel rails and manifold are designed for LS1 style injectors. This third manifold requires the use of LS1/LS6 style injectors and the matching wiring harness. All three versions of the manifold come with custom fuel rails, a stainless braided -6AN crossover hose, an inlet fitting that connects to the stock fuel line, stainless steel fuel rail mounting brackets, and all stainless attaching hardware.

stock the fast is better. however, i have a 96mm typhoon going on my 408 right now, however i had my typhoon ported....the cast is rough. i think with the smooth port its as good as a FAST, truthfully and a lot less......
