Fast 92mm

[71RS/SS396]

hi guys
is anyone using the new 92mm fast black inlet manifold ???? is it worth the $950us or should i just keep my kiwi dollar?? i really like the look of this manifold & am wanting just bolt on inprovements for now. cheers kabrka

The dyno test we've done on the 102 mm showed only a 6 hp gain on a built 427 LS and the gain was way up top in the rpm range. If you had no manifold or you were replacing a truck manifold for a car manifold then it's probably worth the investment but if you already have a manifold it probably isn't. The LS6 manifold is pretty hard to beat for cathedral port heads.
