I’ll do my best to answer the question you asked. I checked part numbers on year one and opgi website. According to their part numbers, the Oldsmobile fan blade will fit. But it is an 18 inch fan six blade. I cannot remember the diameter of the Monte Carlo 350 fan blade. So to answer your question yes, it will physically fit according to year one and opgi. Requires a fan clutch. I would make sure the diameter is correct. According to those two websites, they both call for an 18 inch blade. I hope that helps.

I hope it works for you. It made a difference for me.

It doesn’t sound loud to me. Originally I had that fixed four blade fan on there since I do not have air-conditioning but I do not notice any excessive noise.

I know this may go against conventional wisdom. I have a 350 300 hp with the small radiator. The radiator top cover has three bolts. I bought a seven blade fan put a fan clutch on it but I used the centrifugal fan clutch, I also had the radiator core changed to a 3 row core. I live down in Georgia, it gets hot in the summertime. The temperature does not rise when sitting in traffic. This type of fan clutch from what I understand, is supposed to lock up at idle to bring more air in through the radiator and free wheel at high rpm. Ever since I made those changes I have had no problems. Again, I do not do as much work, or probably have as much knowledge as a number of people on this forum. All I can tell you is what worked for me. John S

I’m not knowledgeable on the heads but the 300 hp 350 had 10.25 to 1 compression. John S

I believe there are two types of fan clutches.The type with the spring, which will work on temperature and will lock up when hot, and another one that is centrifugal. The centrifugal does not have a spring and will lock up at lower RPM and if I can use the word coast at higher rpm. I have the centrifugal one with a seven blade fan on my 1970. I do not have air-conditioning but I have the small radiator that has the three bolt top cover. I replaced the radiator core from a two core to a three core, that along with the combination of the fan and fan clutch has made a big difference, especially being in traffic in the hot weather in Georgia.

It’s not causing a problem I believe if it’s not broke, don’t fix it. I don’t want to start something then cause a problem that doesn’t exist. I have enough headaches I don’t need another one. Thank you very much for your help.

1970

Another question I’ll ask. The transmission is a 1968 Muncie M 20. Serial number P8C11. The car has the wiring for the TCS switch but being a 68 transmission the side cover does not have the switch on it. The car runs great, don’t really know what the difference is with that switch. Would it be worth it to get a side cover that has the switch on it switch it out and wire it in?

I typed incorrectly it is an M 20 4speed not M 22

The seals on my M 20 4speed Muncie for the shift arms on the side cover are leaking. It looks pretty straightforward remove the side cover, pry them out and replace them. Is it fairly simple or am I missing something here? John S

Here are a couple pictures of my 70 small block 4 speed. Your bracket doesn’t look square and doesn’t seem to be high enough.

I see it a lot at these auctions where the price will stall and then they’ll stop the bidding and step in to build up the car to try to generate more money. All that seems to do is reduce the ability of the average person to buy the car they want and make it available only to those who are wealthy enough to afford it. Chances are those who can afford. It are only there to possibly flip it in the future whereas the average guy has a genuine interest in the car and wants to use it for what it was designed for, to drive. John S

Hey Jared, just wondering what do you mean with the 7 inch wheels and your stance?

I also use Aerospace 303, It’s a good product. John S

It’s entertaining for me to listen to people who tell me they have never seen a four-speed Monte Carlo before.They always ask me who put it in. I tell them the Van Nuys GM assembly plant, and they can’t understand that. The other group of people are those that tell me that their buddy had an SS 454 Monte with a four-speed. Anyone can put a four-speed in a Monte, but when I tell them Chevrolet never built one then they usually get quite upset at me. Now I just turn away it’s difficult to tolerate stupidity. John S

Yes this time I come to your neighborhood.

Hello Ray how are you doing. I met you at Summit last year in McDonough talked with you for a bit. This may be a stupid question but I’m gonna ask it anyway. How much gas in the tank now? At roughly 8 pounds per gallon could make a difference. John S

I have 1970 L 48 350 4 BBL in the Monte. The fuel pump is a three line short housing pump. I thought these cars came with the two line pump. The sending unit that was in the car and was replaced with the same style has the two lines on it. I need to replace fuel pump the one that I found is for 1975 Monte with 350 engine I see no reason why that shouldn’t work anybody else have any ideas. John S

I don’t know for sure the amperage rating but I believe it is a 10 AWG wire which I believe is 30 Amp. A fusible link should be two sizes smaller than the wire it protects. For example if you are protecting a 10 AWG wire you should get a 14 AWG fusible link. I think I’m correct on this if not somebody can correct me. John S

When I want to have an intelligent conversation I talk to myself. John S

I don’t think that’s a Caprice. Roofline looks like an Impala with Caprice taillights. Back in the late 1970s my 66 Impala SS had Caprice tail lights in it. I think they look nicer. John S

Those seals that you are showing I believe are for steel inner fenders.
