Are there any Chevrolet parts that are compatible with an Olds 455?

I just bought my first car. It's an 85 Oldsmobile 442 with a '71 model 455. I am interested in sqeezing some more horsepower out of it, but I have a problem. All the big dealers (i.e. Jegs) have all the parts for big-block Chevys. Are there any parts that will fit my 455? And if not, where can I get a good catalog for my G-body?Are there any Chevrolet parts that are compatible with an Olds 455?
i'd recommend google searching it. or ebay.Are there any Chevrolet parts that are compatible with an Olds 455?
The fan-clutch assemblies are inter-changeable as well as the radiator core depth. The carb is another but, I,d chose to modify the stock unit first. Olds quadrajets had very limited accellerator pump circuits. Some rebuild kits eliminated this circuit all together.A 'tight' 71 455 olds needs little in this type of fuel delivery and this is how they can be so thrifty on fuel. Older more 'used' engines benefit (during cold starts) from an active 'pump'circuit that 'primes' the engine for cold starts. Poor cold engine performance can be overcome by slowly adding this 'circuit's capability' to the engine's need's. To do so is a matter of shortening the pumps stem(with a hacksaw) to increase the pump's volume,in this circuit. Start with 1/8 th increments shaven off the top of the pump shaft. A hiss from the 'dry' carb when actuated means it is working.
The only part that will interchange between the two motors is the carb. Everything else is different. You might try yearone.com for a cataloge or an online oldsmobile forum.Are there any Chevrolet parts that are compatible with an Olds 455?
the carb is interchangable vut dont do it, the stupidest thing you could do is put a chevy carb on an olds 455 that motor was completley designed and built by olds and was the best motor ever produced. the early sixtys models ran off of lead fuel and they produced over 400hp and in a super 88 holiday wich wieghed way over 5 thousand lbs it ran 0-60 in 6.2 seconds stock and got an amazing 23 miles to the gallon on the highway. the reason is the carb on the 4barrels they have smaller primarys and massive secondarys so you get good gad mileage at low throtle and at open throttle you get amazing power, the chevy car all four ports are almost the same size wich dose not give you the all around you want. some of the highest rated chevy motors have carbs off of the oldsmobile motors. but when gm bought out olds those carbs were changed over to the chevy style. so i recomend staying with olds parts for that motor. and if you buy a rebuild kit make sure you buy the right one cause the original motor is a 12:1 compression where most rebuilds are 10:1's.
I am shocked - SHOCKED I say - to hear that Jegs doesn't have performance parts for the Olds 455



Google search for Olds performance parts and you WILL find themAre there any Chevrolet parts that are compatible with an Olds 455?
The valve cover bolts are similar and should interchange but that's about all. (undisciplined hackery aside)
