papers on TBI

I posted this one a few years ago:
---
Throttle Body Fuel Injection (TBI) , by Lauren L. Bowler, Engineering Staff, GM Emission Control System Project Center, SAE paper 800164, 2-1-1980.
---

and here's another to add to the thread on US Patent 4,149,496:

http://patft.uspto.gov/netacgi/nph-P...6&RS=4,149,496

and just for fun here's the one (US Patent 5,558,061) for the LS1 head (as it evolved from the LT1):

http://patft.uspto.gov/netacgi/nph-P...1&RS=5,558,061

I haven't found TPI yet but it's probably in there somewhere....

EDIT on US Patent 4,664,075:
