Actually, if you look at Edelbrock's website, they list it as only 58mm. Guess that's not doing my 70mm TB any good now is it!! Guess I'll have to find a bigger one.

I just bought my car so I have not had the chance to really look over each piece that is on it yet.

 

Here we go check out TFS part number TFS-5150SN95, it is 75mm. Guess I'll be ordering one as well.

 

is it alright to hav ea 70mm TB and a 75mm adapter? i would think so but maybe ill just get a 75mm TB since im getttin a new TB soon cuz this stock one and flowing ****

 

I'm not sure. Anyone else have an opinion on this? I have the same problem as well.
