I want to install exhaust. Although the ports have been raised, Wise says that the current intake for the 455 Oldsmobile engine bolts right on to the new cylinder head design. Don't forget to add the correct pickup for the new pan, too. These are highly sought after, and are great for high performance engines. This was the first powerplant to use the smaller Rochester Dualjet two-barrel carburetor; all 260s used it. Moreover, correct tuning was a continual headache.
Compared to the V6, the 260 was also smoother-running, and far more durable. Instead, the legendary Rocket was born, available in Oldsmobile's 88, Super 88, and 98 models. I hope this has been helpful. Every oldsmobile engine came with the crossover style exhaust manifolds with the exception of the W-31's. As for using big block exhaust manifolds on a small block, the right side big block manifold will hit the oil filter adapter.
Use one of each to split the difference. Externally all Olds small blocks are identical. Put 5 gallons in every tank with some 92-octane premium. All the pre-1968 engines used a forged steel crankshaft. They were all painted Bronze and had V and G stamped on the cylinder heads. You may require some fabrication for your throttle linkage, depending on your choice of carb. .
My buddy Tim had a Delta, and went to Northwestern College in Lima Ohio. Check the timing at various engine speeds, then make sure it does not exceed 34-36 degrees after 3000 rpm. I believe the closed system was also introduced to reduce emissions on aging vehicles. On standard heads the bowl area does not make a smooth transition to the valve seat which causes lots of turbulence, inhibiting air flow. Un-bolt the 350, remove the 350 motor mounts, install 455 motor mounts, and then in-bolt the 455.
Note that this decision to go with a smaller bore was also due in no small part to the desire to use a common crankshaft with the new 455 in 1968 as well. The big and small block engine types are almost identical, with the big block having about a one inch higher deck than the small block. General The big and small block Olds motors use identical mounting provisions, so you should be able to simply bolt the 330 motor mounts to the 455 and drop it right in. Big block stock cast iron exhaust manifolds are longer due to the increased block height. The small block mounts were changed in 1970. You need the motor mounts and accessories from an Olds powered car. Even with steel cranks there are more variations of material.
It is one of our dyno carburetors and is a one-off piece. Make some headers for my car! Additionally, Batten Heads in Romulus, Michigan is a recognized Oldsmobile engine specialist that can help you out with head selection and modification on your small block Olds powerplant. They simply capped the crossover on the passenger manifold and ran the exhaust out the back from the factory. All Oldsmobile V8s use a 90° bank angle, and most share a common stroke dimension: 3. Oldsmobile produced the several different cubic inch ratings by changing the bore sizes on their small blocks. I can get a billet crank done at a reasonable cost. Please refer to the and sections as well! If you're considering a small block Olds for your project rod, you will find it to be easy to fit.
For a street vehicle the last thing you want to do is enlarge the port area. On this particular engine we tried a little more stroke in it and the engine really liked it. If you run a stock intake, no problem. Again, the parts book only lists one set of brackets for all V-8s. This sometimes led to overheating problems. Always check rear seat before exiting.
The C-type heads you have should be more like 79 or 80 cc's, so your compression is way less than 10. You'll need to use the oil filter adapter from the 350. This page summarizes the emissions-related information that you may see on this website. Most of the Olds brackets either have two sets of holes or will fit either block, but you certainly want to get as much as you can from the donor car. The holes might overlap just enough to stick the tip of a pencil in.
