Wow! you guys are too technical for me!
Back until 99 models in truck plant here, we made Mexican sixes and trucks that were mostly the same as the old 250's. They had a fuel injection body in place of carb on them the last few years. don't know if you can go to Chevy dealer and get #'s of parts or not. Maybe the last poster is talking about this engine as it was made in Brazil I believe. It's just a stock set-up, not racer, but may be better than a carbed one.
