Re: Why do so many frown upon swapping Chevy engines into Ol

I was just gonna say up where I am...there's Chevy, Ford, Mopar or Tuner =(. I agree with the whole idea of it being all GM anyway. That being said I have always wanted and loved both the olds 455 and the chevy 454 and LS engines as they progressed. I have had 3 cutlasses.
1st was rust-bucket maroon 85 with 231 Buick junk and 200c junk 3spd, I was still in high school and on a serious budget. I ended up falling into an 84 Regal with Olds 307 and a junk 200c that was hit in the rear and totaled. So there was my 1st motor swap and it was great. Sold that one and made some cash.
Next I got a gray 86 cutlass with 307 and unfortunately another 200c junk and bench seats...was in better condition than previous rust-bucket, this is still my daily driver now. She is bruised and battered from NY roads and weather.
When I got my 3rd cutlass (the one in my signature) it was an 84 beige cutlass with Buick 231 and 200c junk again, but this one had everything else I wanted. Dark briar brown interior, bucket seats, floor shift, rallye gauges, rallye rims and it was real clean with the exception of the d/s door rot. I went the Chevy route with this one b/c in my opinion the sheer fact that they are a more popular motor there is the direct correlation that parts will be cheaper, parts will be easier to obtain, more diversity of parts(brands, designs, materials), and finally more research & development to design better quality and performing parts. So now my 3rd cutlass is powered by a Chevy 355 and a 700r-4. I felt with 350 & 455 Olds engines like I was limited to such few choices for parts. For example I could really only find 3 different intake manifolds and they were all about $200 more each than Chevy. So another factor became where as much as everyone might have a Chevy...it seemed all the Olds must look almost the same.

That being said the 4th cutlass that my dad owns is a gold 87 cutlass with an Olds 455 and 200-4r, and it's freakin badass lol. The only thing that scares me into maybe going 454 or LS with my next build is watching him get aggravated trying to find parts that he needs, and parts that he likes(he gets jealous that nobody makes sh*t for dressing up a 455, like sheer amount of valve covers, intakes and pulley systems they make for other brands like Chevy and Ford. I do have hope seeing builds like FE3X's and I thing someone on here was also building a badass looking and performing Poncho 455 I think.

Sorry for the rant. It's Okay to put a Chevy in your Olds. I love the car either way and get compliments all the time. I love doing all the work myself. To me the biggest thing about any build is the quality of the work and that is up to you and not the brand title.

I don't see anything wrong with it, I'm even considering it. THing is, everybody swaps SBCs into everything. Restoring a 40s roadster? Put a 350 in it. Restoring a truck? Put a 350 in it. Nothing's wrong with it, it's probably the smart way to go, because the more popular something is, the more parts there are, more variety, and everything will be cheaper. I'm just one of those guys who wants to be different, so I'd vote for an Olds or Buick. That's just me though, price and difficulty doesn't matter if you have a passion.
 
Re: Why do so many frown upon swapping Chevy engines into Ol

I honestly don't think it's an issue. But if I did put a Chevy motor in the car, it would NOT have the valve covers, air cleaner, etc. that has Chevrolet written all over it. Hell, I am contemplating putting in a Caddillac 4.1 V6 in my GN. As long as GM parts stay with GM cars, and Ford stays with Ford, I don't think it would bother me. However, I'd like to keep the original way the car was built in tact. For example, I would NEVER put a V8 in a Grand National. It's got the power 6 all over it. It originally was a V6. So I would have no issue installing a different V6 so long as its GM. On the 442 side, I would make sure that it has a 4 barrell, 4 speed and dual exhaust as it was meant to be. Everything else can be left to the imagination. Call me anal, but that's my opinion on how things should be done.
 
Re: Why do so many frown upon swapping Chevy engines into Ol

I think since (at least up here) a lot of the non Chevy gbodys came with 305s anyway it's not a big deal. I would go with what looks more original and would be easier to swap. When going from a V6 to V8, go with what you can afford.

I would rather drive a Cutlass with a cheap built SBC than look at it in my driveway/garage waiting until I can afford a built Olds engine.

mainly because it sets our cars away from every1 else's and is the correct brand for our car. Everyone and there brother has a Chevy Engine.

this is why many choose to run an olds engine.

but i understand that it's cheaper, but you asked for the reason and I told ya...lol


Its also cool to say you got an Olds under the hood when the dude you outrun asks what ya got 🙂

BUT TO EACH THEIR OWN, I'M NOT GONNA HOLD A GRUDGE, I'M JUST GLAD PPL ARE FIXING THESE CARS UP
exactly.....
True..GM put chebbys in oldsmobiles, and buicks in oldsmobiles...but GM wasnt concerned about brand loyalty and most customers back then didnt care about what engine was in what car. I think the fact that Olds is out of business, as is Pontiac, makes keeping an Olds/Pontiac even more important and if its got a real Olds/Pontiac powerplant in it...it only adds to the originality of it...JMO

lol I do have to agree. Personally I would love an Old gbody with a bit gold Olds engine in it. 8)
 
Re: Why do so many frown upon swapping Chevy engines into Ol

I put a Buick 350 in mine for the only reason that it would bolt right up and be a direct swap from the original BUICK engine that was in it. Although I say that the build was a little tougher to find parts for, but i'll tell you ....everyone that it sees it says, at least it's not a Chevy swap, everyone does those. So I am quite glad I did something "different." Finding stuff for this car has made me friends from having to root around for parts. THese friends I would not have if I had everything available from Summit Racing. Different outlook on the whole experience you know. This is my 3rd play car, not a daily driver, so it's a hobby and an experience that I truly enjoy all aspects of.
 
Re: Why do so many frown upon swapping Chevy engines into Ol

I'm CHEAP. EVERYTHING I do is on a budget. EVERYTHING. But I'm here to tell you, I have never spent less money building a Chevy V8 than any other GM V8.

Now, I said I'm cheap. I do all the assembly and rebuild of the engines myself, in my garage. The only thing I pay for is machine work because I don't have a machine shop in my back yard. Dollar for dollar, I typically spend MORE money on Chevy engines at the machine shop than I do Buick, Olds, or Pontiac. I think its probably that Chevy engines were run through the mass production line with far less attention to detail than the other GM stuff was. I can't tell you how many Mexican 305 and 350 blocks I've given away because of the cost of machining. The Olds stuff tends to clean up easily at the machine shop.The blocks and heads are good castings, not prone to cracks or needing repairs. The cranks clean up nicely most of the time. If I need connecting rods (the Olds' weak link) I can use aftermarket Chevy rods, 6" long, and have the crank pins turned down to the Chevy size.

Olds and Pontiac engines need oil restrictors put in the block to keep more oil on the crank and less in the valve train. Easy and cheap.

Buick stuff just needs the oiling system gone through thoroughly with one of many books out there to do it. You can do it all in your garage. Ditto with the good iron from the factory not needing a ton of machine work. Most Buick heads have such high nickel content in them you don't even need hardened seats to run unleaded fuel. Buick Cranks and rods are very strong in factory trim.

Much detail must be paid to assembly of the engine. If you take your time, buy a proper book for your engine (like the Mondello books for Olds) and follow those instructions, you'll be good to go for a long, long time.

Chevy blocks will almost always need to be bored out. They almost always need to be align-bored or align-honed. 80% of the B-O-P blocks I check in the garage don't need it. Chevy blocks are prone to cracks and more often get tossed than the others. Ditto the heads built before 1995. Vortecs are good heads, and blocks too, and other than those I wouldn't even start a Chevy build.

Intakes, camshafts, headers, and all are not that differently priced anymore. I think people get Chevy on the brain because that's what all the people that they know run, because they don't know any better.

If you're on a severe budget, I don't see how you run a Chevy for any length of time. By the time you replace everything inside the block, it didn't save you any money.

If you just think of knowledge as power, and spend your money on books and measuring tools (and a die grinder kit for head porting) you can make LOTS of power for reasonable amounts of money. Or you can just throw tons of money at your engine and have someone else do it.

As it pertains to this thread, here are the 3 potential factors to consider to run one particular engine family over another.

1. What family of engine came in the car? Its cheaper to put a Buick small block (300/340/350) in where a Buick V6 once was, or easier to run any Olds V8 where the 307 was, or easier to run any Pontiac V8 where the 265/301 was. If your car started life with a Chevy small block and you are on an extreme budget, then you need to hit the wrecking yard and start with a 350 Vortec long block from a truck. That will give you some budget horsepower. The engine already has great heads, and is a roller cam block as well. If your car came stripped or without an engine, then your decision of what family to run in depends on what the donor cars at the wrecking yard have to offer. If you run into a complete V6 Buick powered Regal, then pulling that engine out, taking all the accessories and motor mounts (fan shroud, etc...) will give you a complete swap package for your future Buick small block V8. Ditto if the car happens to be a Monte Carlo with a 305.

2. Your level of experience or ability to do things yourself. Tools are expensive, and books aren't free either. To rebuild any particular engine properly, you need some sort of guidance. If you are severely lacking, Chevy info is easier and cheaper to get, and the tools you need to slap one together are readily available and usually easier to borrow from someone.

3. What free stuff do family and friends have to donate to your budget cause? Sometimes if an uncle has a spare running 350, it cuts a lot of cost out of your initial plans.

Good luck however you decide to get your project done.
