Their Buick City rejects passed to Pontiac as seconds
I did not notice this on my 87 Delta spare engine but not sure I got a good look. Its not in the best place to see that side either plus it has a cap closing off the man. I check it out tomorow.
My opinion on the HO thing is this. It was sales propaganda. Because there is no low output engine. Thats why I hate to see people posting High output classifacation for an engine. It could mislead early learners that their engine is special. They are all the same. All LG2'* (1986) had 140 (irrevelent for Pontiac owners) All LG3-3'*(1987) had 150(possibly why the LG3 was called HO,it was an upgraded LG2) all LN3-C'* had 165. Doesnt matter if they were in a 98 Regency, Riviera, Cierra or whatever they were all the same. Anyone knowing positive infor on different outputs for various models with the same engine ,Im listening but I have never seen a low output or lets say non HO LG3-3 engine.
What engines did not have tubular manifolds ? Remember I never had a LN3-C. Pretty sure my 91 L27 has tubes. Ya keep making me second guessin
That and I have to many engines, to many projects and too many years on my tired brain.
