What else can I help you with?
Can a intake manifold and other parts be interchanged between a olds 455 and a olds 400?
No.
Is olds intake manifold interchangeable from 350 to 455?
No, the intake manifolds for the Oldsmobile 350 and 455 engines are not interchangeable. Although both engines are part of the Oldsmobile V8 family, they have different dimensions and designs. The 455 has a larger displacement and different port sizes, which means that using a 350 manifold on a 455 (or vice versa) would lead to improper fitment and performance issues. Always ensure compatibility when considering engine components.
What is the correct firing order 1968 455?
Don't know off hand, but it should be molded into the intake manifold. 1-8-4-3-6-5-7-2
Will a 1976 455 Pontiac engine from a Grand Prix bolt right in a 70 GTO and can you put your 70 heads and intake on it?
Can you bolt on earlier heads/intake/exhaust manifolds.. from a 1970 Pontiac 455 to this 76 455 engine.
Are Oldsmobile 350 455 heads interchangeable and if not please explain?
Yes, but with some note worthy issues. The heads will bolt to the block, but you will have a large intake port mismatch (the 455 intake ports are about .300 taller than the 350 ports.). You can not swap intakes to cure this, since the 455 has a taller deck height than the 350. You can however, port the top of the intake runners on a 350 intake manifold to get them closer to the 455 size (an Edelbrock Performer RPM can apparently be ported to match), or port a 350 head to get it closer to the 455 intake. Be careful to not remove too much material. There is also the problem of compression 455 heads are listed as 72cc combustion chambers, but usually measure closer to 80cc. 350 heads are listed at 60cc and are about 60-65cc. Swapping the 455 heads onto the 350 will loose about 1.5-2.0 points of compression. Results will be around 7-7.5to1. You could do it with coustom pistons to get back the lost compression. 350 heads on a 455 will raise compression too high for pump gas, and have smaller ports and (usually) smaller valves, not good for performance.

Which motor has the most horsepower a Pontiac 455 or Buick 455?
The Pontiac 455 came in 3 versions. Base, High Output, and Super Duty. The base 1970-71 engine produced 200 hp and 455 lb/ft torque. The Super Duty 1970-71 engine had 335 hp and 480 lb/ft torque. Power was reduced after 1971. The Buick 455 came in 2 versions. The 1970 Base engine had 350 hp and 510 lb/ft torque. The Stage 1 engine had 360 hp and 510 lb/ft torque. So as you can see the Buick was the more powerful engine by far.
What are the rocker arm torque specifications for a 455 cubic inch Oldsmobile engine?
According to most Oldmobile torque specs, the correct torque for rocker arm bolts is 25 ft-lbs.
Vacuum line routing diagram for 1075 Oldsmobile Toronado 455?
For the 1975 Oldsmobile Toronado 455, the vacuum line routing typically involves connections from the intake manifold to various components like the brake booster, carburetor, and HVAC controls. The vacuum advance for the distributor should also be connected to the manifold vacuum. Make sure to check for any specific routing diagrams in a service manual, as configurations can vary based on equipment and options. Proper routing is crucial for optimal engine performance and operation of accessories.
Where do you put a temp sender on a 455 73 Pontiac for an after market gauge?
Depending on which intake manifold you have there may be a plug in it near the thermostat housing. Also, each head will have a plug on the side. One is usually fitted with the sensor for the original gauge. This is the usual spot for wiring in an aftermarket gauge.
What is the best size carb for your Oldsmobile 455?
750 cfm if you go too far over it will bring your torque down
How much horse power dose a 2001 Chevy 2500 HD 6.0 have?
360 hp 455 ft lbs torque
What is the weight of a 455 engine?
about 500-600 lbs it depends on what-all is still on it, whether it has the AL or iron intake, etc.
