I bought a 90mm fast tb which i got a good deal on, and now theres a good deal on a weiand intake which I will have ported to fit the 90.
My question is will the fast 90 bolt patern fit on the the weiand bolt patern because I know that the 90 doesnt fit the stock bolt patern...I just didnt know if the weiand bolt patern is the same as the stock bolt patern.

Anyone have any experience with this combo, sorry if theres already a thread on this, i tried the search with no luck

no it won't fit,the weiand intake is a 3 bolt design.look for a used fast,I see them go for $600.

Edelbrock makes a 90mm TB with a dual bolt pattern that will work.

thanks for the replies guys....but the fast tb that i have is a 3 bolt patern but its bigger than the stock paterns because when i got it i tried it on my stock 99 ls1 intake (not the ls6) and the patern was further apart if that makes sence

and the intake im lookin to buy is a polished unit for $250 and im going forced induction so if anything i would rather get a different tb and go with this intake, what do you guys think?

You can tap 2 new holes to make the TB fit or find some spacer in ebay that let you use a 4 bolts TB into a 3 bolt intake. I used the weiand intake in the past and like it that is why i both another to my set up.
