Just bought an 86 SS Conversion?? - 02/22/16 11:20 PM

Hey guys, this is my first post on the forum, so please don't grill me too bad for posting something that may be a deep records copy. I have already looked some of it up, but have not gotten direct answers on any of my questions.
I bought a 1986 Monte Carlo SS with a 350 motor in it. Not sure what the motor came out of or how many miles are on it. I have changed the upper and lower radiator hoses, the water pump and the thermostat. I bought all new belts as well.
What I was wondering is if there are any kits for replacing vacuum lines, kits for wire connectors that are broken, and im looking for motor mounts. This car is not going to the track at all, so I don't necessarily need top of the line but if it doesn't cost much more to do I'll go the highest quality route.
Other than the previously stated parts, what recommendations do yall have for things that will need to be done for longevity and driveability?

Second, I'm not quite sure what all was done before I owned the car. I'm 99% sure the stock 305 has been replaced with a 350. And I am 75% sure the previous owner modified the means of shifting by moving it from the steering column to just in front of the center console.

Thanks for any and all usable info!

There are no kits that I know of for what you want. But all of the electrical connections are available you just need to know what your looking for or have a smart parts guy. For the vacuum hoses. Parts store and get a couple different sizes and plenty of it. Change one hose at a time. Stock motor mounts will work. 305/350 are the same size on the outside and the way they they bolt up.

All Monte Carlo SS's came with a 305. Your 350 is not stock but it is a common modifcation.
Moving a column shift to the floor is a common modification.
Repairing vacuum lines is best done one at a time. Take one hose off, cut a new hose to length and reinstall.
Wire pigtails to replace your broken ones are available. Again do one at a time.
Is the 8th digit in your VIN a G?

Try to look on the back of the engine for the casting number and then google a casting number decoder and run the number so you have a better idea of what block you have. Good advice above about doing anything 1 at a time to help eliminate any confusion.

Look at the front right (passenger side) of the engine block. There is a machined pad that will have a code on it. It can be decoded to let you know the engine size and what car it came from.
You will have to clean it off and use solvent on it.

Welcome to the site. I am from Houston as well.

Our cars did have the option of a floor shifter from the factory.

Like mentioned above, replace one thing/hose at a time that way nothing gets missed up.

You'll find a ton of information here and write ups on pretty much any mod that can be done to the gbody.
Post a pic when you get a chance.

Thanks for all the info everyone! I am feeling a bit under the weather so I won't be investigating any further until I can get well. But I figured I would try to post some pictures of my steal. Give me a few hours or so to refresh myself with this forum and figure out how to get a quality picture posted.
Thanks again for all the info!

The 8th letter being a G means it's a real SS.

I might have finally figured out how to post pictures.

This should be day one after I put tires on it:



This is what the story was under the hood:




Here are the guages to replace the non working dash gauges:



Here the thermostat I pulled out:



Here's after I removed the wiring harness, old radiator, old water pump, old thermostat, old distributor and old carb. Replaced all new of course:



And here's the passenger side wrapped header, and the car lifted and almost ready to install passenger side header:

Well the monte is almost finished. Last night I ran tiny copper tubing to an oil pressure guage in place of the old bulky sending unit behind the drivers side header. The transmission lock up kit is spliced in, the new 4th gear pressure switch is in, and the vacuum switch is wired and ready.
The exhaust was a bit of a tricky situation. I ordered a 2-1/2" header back with no mufflers, and used the old mufflers from the oem exhaust. When jegs put together the package they sent a brochure, but no instructions. So I winged it, and now the exhaust is dumped directly behind the mufflers.

Just a tip for anyone planning on changing manifolds for headers: the ac compressor bracket that bolts up off a stud on the drivers side. Yeah it won't fit over the new exhaust primary. I did some modifications because I'm on a pretty strick time line. But they sell adapters, and I would recommend this highly, especially if you don't have the tools to fab the correct geometry into the new homemade bracket.

Also recommend thoroughly thinking the process through before purchasing headers. Not only are they time consuming to install, but there are sometimes a few things that need to be relocated. The oil sending unit on the drivers side is one of these items, the starter is a tight fit, and most of the spark plugs had to be shorties, and tightened with a wrench.

Don't let the kit tell you it's a simple drop in system. Also don't let YouTube fool you into thinking you can replace the rear transmission seal in 5 minutes, at least I couldn't. Under the car for an hour before I got the old seal out and new in.

If anyone has amy questions feel free to ask, if you're in the houston area and wanna meet up after I get the tuning done (if all goes well today) hit me up.
