I'm doing a TT 5.3 liter. It's a 2005 engine, TB, harness, pedal, everything. I really want to go with a Holley Hi Ram 92mm because it'll look better with my high mount turbos (going in a 47 Chevy sedan Delivery). My question is this: What's the easiest route to go for a throttle body that'll work with the Holley Hi Ram? My biggest concern is getting it to work with my current harness, pedal, ecm. Obviously there will be tuning involved, I just haven't decided on a route to go yet. Would an LS3 90mm TB bolt up to the manifold, work with the pedal, and be tuned to open properly? Is there a different option I should look at instead? I may still cough up the money for a Holley Dominator ecm before I finish the build, will the chosen TB work equally as well with the Dom? Thanks in advance.

look in the Help section on the holley software, it has part numbers for which TBs work with the holley.

There is a Holley support document that lists the part numbers for the TB that will work with the Dominator.

Thanks for the help. I found the part numbers for the 4 gm throttle bodies that work with the Dominator. For anyone else that may be wondering they are:
12570790 off of 05-08 LS2,
12580760 off of 05-08 Tahoe/Suburbans,
12570800 being the 3 bolt my 2004 and 2005 Silverado,
12580195 off of the pontiac solstice.
Are there any 8 pin 90mm dbw options available that would work with the stock computer. Still struggling with the cost of the Holley system though it's probably the best idea in the long run.

If your build requires a lot of programmable input and outputs, there is no better system than the Holley Dominator. It's capability is only limited by your imagination.
