Alternate throttle bodies ?

[vortecfiero]

are there any round throttle bodies that use the same IAC and TPS as the stocker?
or one that uses newer style sensors that, with the correct harness plugs, will be in
the ranges of our ecm ?

thinking about fabricating a new upper intake... fabricated from available box tube 4 x 4 or 4 x 6 etc
i have access to cnc equipment and a very talented operator/designer who is also a car guy

thanks

I know the LS1 uses a round TB, dont know about sensor compatability though. Some LS1's ared drive by wire- no throttle cable attachment either. I think a Buick turbo GN uses a round TB, and they are from the same era as our tucks so the sensors probably interchange.

My home made intake is done for Infiniti Q45 throttle body. The Q45 has throttle diameter of 90 mm (3.5").
Should be big enough

Got the throttle body from Ebay for something like $40 !!
