the best would be 1.75 inch
Most of them have 1600cc engines. Be careful, now: 1969 was the last year of the 1500cc engine. Volkswagen often built or bought more parts than they needed for a particular model year. If they had 1500cc engines sitting there when your car came down the production line, that's what they installed. You can't get 1500cc piston & cylinder sets anymore because 1600cc sets fit perfectly.
More information is needed to answer this question properly, such as; is the engine a 4 or 6 cylinder. In the case of a 6 cylinder, their are 2 exhaust manifolds; the front exhaust manifold is located under the hood between the radiator and the engine: when you check your oil level by grasping the dipstick your hand will be just a few inches above the exhaust manifold. Basically, follow the exhaust pipe(s) to the engine and where it connects to a device that splits the exhaust 3 or 4 ways, that device is your exhaust manifold.
It has 8 intakes and 8 exhaust if it's a V-8 engine.
it depends on what year the motors are you will have to change motor mounts .exhaust maybe front suspension
Different engine, wiring, computers, abs sensor at the left front, trans, exhaust, radiator, ac lines, .............. Easier to buy a different truck.
It is not good for the engine if it is the original setup from the 1970's. Lead is needed for lubrication to the valves. A reconditioned engine can use unleaded fuel if the intake and exhaust valves and the seats are replaced.
The car's engine will die. Although it probably doesn't do any damage to the engine, if exhaust can't escape the car, then the car can't filter out fumes to intake fresh needed to run the engine.
It depends on the type of engine. In a four-stroke engine, there are four strokes - intake, compression, power (combustion), and exhaust - required to complete one full rotation of the crankshaft. In a two-stroke engine, there are two strokes - compression/ignition and exhaust - needed to complete one rotation.
The exhaust system will change the air flow to the engine so the power commander is needed to re-map or calibrate the system again so that it is optimized. If you don't re-map the system then you will not get the full benefits of the exhaust.
It is located directly above and at the forward end of the starter just beneath the right bank engine head. Depending on the type of exhaust system you have it may be needed to remove the starter and or the right exhaust pipe from the manifold
If the 454 is complete with accessories such as exhaust manifolds, a/c, power steering, alternator, etc., it should be a pretty straightforward swap. Transfer the motor mounts and distributor from the 350. A new exhaust system will likely be needed.
