TB- Tunnel rams

[l9meup]

what 4150 throttle bodies "cheap-ish" do you guys use on your tunnel rams?
looking at the aeroflow / proflow 1375cfm jobies.

There are those or I think Edelbrock does a decently priced one too, have a look on Summit or Jegs in the US. But try to find one that uses GM style TPS and IAC so it's plug and play.
