Default Is this a 90mm tb/J-tube question

My buddy has a 4 bolt throttlebody that he says is 90mm for an LS series engine. He doesn't know what it came off of though.

I measured it and the bore (backside towards intake) measures 3.41". That comes out to around 85mm. Did they make an 85mm tb or am I measuring the wrong area? Also, it has a 6 pin connector on the side for the throttle valve/tp, etc.

Also, where do I purchase the J-tube option for the maggie blower? Thanks.

Doing more research, it appears that this mod may not be worth the dollars (very minimal gains)....... Anybody have definite results (a tenth, 3 tenths, etc)??? Thanks.
