Where can you get a diagram for which spark plug wires go to which plugs on a distributor cap for a 1972 Oldsmobile Ninety-Eight with a 455 engine?
Answer 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 horsepowe…r). 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.
Yes, but you must use the olds motor mounts. They are a 2-piece unit. The half that bolts to the block can be purchased new. the half that bolts to the frame is a little… more difficult to find. Retain these from the donor vehicle if possible. If the engine/transmission is from a larger vehicle (i.e delta 88, or 98) the TH400 tranny will likely be a long tailshaft version. this will require that the driveshaft be shortened and/or the crossmember relocated. Make sure the motor mounts on the block are attached at the middle location, not towards the front. All GM A-body cars from 1968-72 share the same chassis and firewall location, so any motor from any GM division of the era will fit. I highly recommend you upgrade to a 4 core radiator and heavier 'big block' coil springs in front.
Firing order for you're Rocket engine is 18436572 distributor rotation is counterclockwise. Cylinder one on the distributor cap points to cylinder one.
Oldsmobile stopped production of the 455 in 1976. There were no 455s produced in 1987.
This size motor was manufactured from 1968 - 1976. In order to find the exact year there should be a number 1 high casting on the bottom left corner of the block.
The bhp of the 455 olds in 1973 was 225 in delta wagons, delta 88, and olds 98-bhp for toronado was 250 and this engine was optional in cutlass-compression ratio was 8 t…o 1 with deep dish pistons. It has a 4.13" bore and a 4.25" stroke standard
pick up a chiltons manual for your car at the library.
You can get a wiring diagram for your Oldsmobile 455 cubic inch engine alternator at most auto-parts stores. Oldsmobile service manuals will have the engine alternator wir…ing diagram and can be obtained from most local libraries.
try the local library and get a chiltons repair manual for your car.
I am not sure what your question is but the term rocket really has no meaning in relation to any specific olds v8-it just means that it is not a flathead motor. olds and Cadil…lac introduced the first engines in cars that were not flathead engines in 1949 and Oldsmobile needed a new catchy name for their new engine-since engines at that time had no (rocker arms) for valve trane this was something new and someone decided to call the engine rocket. as far as the 72 455 goes they had anywhere from 225 bhp to 300 bhp depending on application. the bore is 4.13" and stroke is 4.25" and should only have a 8 to 1 compression ratio with low compression pistons-olds determined compression ratio with dish in pistons not cylinder head-although D cast heads had a smaller combustion chamber than the rest
Oil filter location should be on passenger side rear of block
The 455 will fit. The transmission might have a shorter tailshaft, though.
yes if you have the Oldsmobile motor mounts. If you are asking if engine parts will interchange....Absolutely not.
Go to library and get a Chilton repair manual you can find most of your information for engine diagram.
