350/th350 going into 82 Cutlass supreme w/ 260

[DrRansom442]

As far as swaping from an olds motor to a chevy motor it is not nearly as complicated as people make it out to be and is really cheap to do. Hell if you have a complete motor all you have to buy is $20 worth of motor mounts, which your motor mounts probably need changing any way and the chevy mounts are cheaper then the olds mounts, and your done. Then just move the battery tray to the other side of the car and adjust some wiring. The fuel lines are on the right side with the 260's. Radiators are the same between v-8 olds and v-8 chev g-bodies. It's not like putting a ford motor in one.

Yes, engine swaps are always this easy ... just change the mounts and move the battery Costs associated with building an Olds are absorbed by the parts needed for the swap and you know the Olds is a direct fit.

I gotta say I agree with gsdewd on this. People are over complicating swapping in a sbc. I don't understand why people are so against it. I'm not even gonna go into what motor costs more to build. Most people build whatever motor they want, or are most comfortable with. I have nothing against bop engines. GM made all of it so why the hell does it matter.

Actually I wouldn't even consider this an Engine "swap" as it is a direct bolt in that doesn't cost crap to do. I am still trying to figure out why people keep saying it's cheaper to stick with and build and olds motor. I am building my car on a extreme budget and I did my homework. It is going to cost me a little more then half as much to build and install a chev motor then build a olds motor. First you have to find a motor. Finding an old motor for cheap to build is not easy. I just bought a 71' vette 350 4 bolt for $200.00. I'll have roughly $2000.00 in it And with the $20.00 motor mounts it's a done deal. I already have a built 350 th trans and some of our cars came with the multi case trans so that is no prob on some. An engine swap would be like putting a ford or chrys. motor in our cars. A chev motor is a bolt in. It's just like putting a sm blk in a omega or a ventura same deal.

Plus, these cars come from the era of corporate drivetrains. Chevy engines wound up in G bodies from all 4 divisions at one time or another. That is one of the reasons I went Chevy, it could still be a sleeper as most people not intimately knowledgeable about what engines went in which models what year would think it was a 305 and factory. I even went so far as to use the proper 1985 SBC harness out of a GP. Almost everything worked perfectly by doing so, with the exception of the tach wire and the oil pressure idiot light. The rest of the pins are the same in the engine harness connector. I haven't fixed the idiot light yet, but I hacked an Olds harness for the tach wire and just slid it in the empty slot in the bulkhead connector. The Olds setup did not use the filter that the others did.

We can compare notes when done but my SBO build is half your Chevy ... even my core was cheaper. Now who is going to have an easier time fitting it in the framerails? I can reuse the starter, waterpump, all accessories .... as a matter of fact - I am. An Olds can be built on an "extreme budget" it's done all the time and when it's said and done I still have an Olds. You'd have had an easier and cheaper time starting with a Monte Carlo.

What I am curious about is the weight of the Chevy 350 vs the Olds 350. To me that is a HUGE consideration in choosing an engine. I did my swap (from a Buick 231 V6) back in 1996 or 1997 and did not have the data back then. Today, however, I would probably not use a Chevy 350 but rather an aluminum block LSX as it would help withe the weight distribution issue these cars have for handling.

I only have 300 in my motor with the original purchase cost for the engine(complete and running) being 400.

Given I got a block with crappy windowwed mains ... I'd bet weight is pretty close. An SBO and a SBC are about the same size a BBO is actually smaller than a BBC

I found this googling:

http://fixrambler.com/engineweightchart.txt

he lists 330-400s at 560 lbs and the typical SBC at 575 ... Early Olds all had solid mains. So I guess I'm quite a bit lighter than an SBC

Well, I was hoping my sub $200. core was going to be a drop in, but after taking the heads off and finding a round cam lobe ...

so gaskets, bearing and rings got orderred
tank got boiled, tested and just a hone
crank needed polished but we just bought new
new cam
then I found some heads

It's just been a big snowball
