GM 87mm DBW Throttle Body

If they were out of a flex fuel truck... yes then they are suppose to be 36# injectors, but the actually put out more like close to 40# but, the non-flex fuel trucks have 24# injectors. the only other motor that had different injectors was the 8.1L. and just because you have returnless style fuel system does not mean that your flex fuel either... that was just something they started in the 04's

I checked for Zeake, the PN he gave me are for the E85 injectors. Confirmed the rated flow rate with a contact at Delphi..

And there were other injectors out there with that same intake, TBSS and SSR's with the LS2 had something between 24 and 36, but I do not have my cheat sheet in front of me to confirm the actual flow rating.

That intake started out on the 2005 V8 Rainiers/LWB Trailblazers and Envoy's, and is on all the GenIV cathedral port motors (4.8 and 5.3L, some 6.0's like the LS2 and hybrid trucks) now.

All "NNBS" trucks except the L92, LY6 (iron 6.0), and L76 (Aluminum 6.0) have this intake, but there are E85 and non-E85 injectors in the fuel rails, so ya gotta know the PN's..

Rectangle port head motors have a similar looking one, but it's a bit bigger, though with the same 87 DBW TB.

Throttle body is still available. Some one should buy it and have it ported then sell the one they already have.
