Best Answer

To get a 400 Pontiac Motor in 1979, you had to also get the 4 speed. Pontiac last manufactured 400 motors in 1978 but saved some from 1978 for use in the 1979 model. Those motors were used in the 1979 4 speed cars only. 1979 Automatics had the Oldsmobile 403. You could also get a turbo version too. All of which could come with auto trans. I worked on many of these at the Pontiac dealer.

What are the torque specifications for a 1979 Pontiac 455 rocket engine?

In 1979 Pontiac did not make available any 455 (cubic inch) engine. The largest available was a 400 4bbl in the Pontiac Trans Am (220 net horsepower). Also the "rocket engine" description was only applicable to the Oldsmobile Division. The 455 Rocket Engine (Oldsmobile) was discontinued in 1977 where the largest engine was the 403 cubic inch Rocket Engine V8 rated at 185 net horsepower available on the 98 (a 350 cubic inch was standard) and the Toronado. It was also sold to the Buick division and available on the Riviera.


Where is the oil sending unit on a 3 8 1995 Pontiac engine?

There is no such thing as a 1995 Pontiac engine. IIRC Pontiac engines were last used in Pontiac cars in 1988, and in GMC trucks in 1992. A 1995 Pontiac may have a Buick 3800 engine with the oil pressure sender screwed into the block just above the oil filter. You might have a Chevy or Oldsmobile engine..... but unless it's a V8 your oil pressure sender should be very near the oil filter.

i think the GTO has the LS2 6.2 That depends on what your idea of a Pontiac engine is. The "New" Pontiac GTO was available with the 6.0 engine. If you are talking about a traditional Pontiac engine, the largest factory offered engine is the 455 from 1970-1976.
