The time chain is located under the timing chain cover, which is behind the fan and under the water pump.
It's an Olds 403.
I didn't see a specific year year you're interested in, however a 1978 Olds 403 is listed as 18 degrees initial timing (detach and plug vacuum advance hose while setting initial advance).
The blocks were physically the same size so I don't see why not.
Intake manifold torque specifications for the Olds 403 is listed as 30 ft-lbs.
The spark plug gap for a 1977 Olds 403 is listed as .060 inches.
No, the blocks are different.
a lot could come to play are you going to do it or have it done do it your self 300-up pay some one700-up
from factory they offered a Pontiac 400 w/ 4-speed or the Olds 403. 301 was also available.
When replaceing the toronado engine, The intake and carb must come from a toronado or Riviera because it is lower. The 78 came with a 403. A 307 or 455 Olds engine will work also as long as you put the low profile intake on
Place timing marks dot to dot using a straight edge from crank center to cam centerline
You can tell an Oldsmobile V8 when you see one. You can also look at the casting numbers and engine suffix code, both of which will tell you that it's a 350 Olds rather than say, a 307 or 403 Olds.
yes i think so
