65 Cutlass Convertible to LS/4L60e + complete frame off
I bought this car about 2 years ago but never got around to starting a build thread on it, unfortunately most of my early pics got deleted somehow so figured I better get started on the updates.
Couple pics of the car stripped to start but unfortunately none of the whole car I bought. Some of the pics show the rust but there is not very many areas that don't require major rust repairs
Frame was pretty much toast so acquired a new one and a ton of 65 parts for a great price.
Frame sand blasted and painted a hammered silver

Next I rebuilt the rear diff (i had a posi) and changed the gearing to 3.73 for the 4l60e overdrive transmission, should have nice power off the line and cruise at around 2500 rpm on the hwy. Found a nice chrome diff cover for it for looks also.
Upgraded all the brakes and suspension at this time also, I went with 2" drop coil springs on the rear and 1" on the front as the new a-arms are supposed to drop it 1" also.
As for brakes I purchased an aftermarket set of C5 corvette for the front that used the stock drum brake spindles, these are 13" drilled and slotted with twin piston calipers.
For the rear I read about using 98-02 Camaro/Firebird 12" disc with a built in e-brake, found a used setup on e-bay for $175 that were like new so i cleaned them all up and painted them to match the front and ordered some new drilled and slotted rotors to match also.
forgot that I also purchased a rear control arm boxing kit and sway bar from Summit at this time also
this is the front brake kit that i purchased from e-bay for $330 at the time
here is a link to a video about the rear brake swap but there is tons of info on the net about it
Hope some of this is of interest to people, Over the next few days I will get up to date on my progress so far but here is 1 pic of the engine

I finally got time to do some more updating to get to where the build is at now, some of this is not in the exact order i did things but it all ends at the same place so on with the show
i added a few inches on the transmission cross member support to accept the 4l60e
The engine I ended up using is a LM4 aluminum block from a 2002 Chev Trailblazer (Buick Rainier, SSR and possibly couple other models also are the same)
When it was time to fit the engine in the frame it was kind of read something on the net and then figure out if it would work, in the end I used regular GM clamshell mounts with a 1/2" aluminum spacer under them and the billet ls swap plates to mount them to the block, I actually got it mounted and in a good position pretty easy with lots of clearance for the firewall and used the Holley 302-2 oil pan for clearance as you can see in the pic it doesn't hang below the cross member at all.
When it came time to choose all the accessory drive components I went with all LS Corvette , I got some really good deals by searching the net and some from Rock Auto and Ebay, the Holley oil pan came from craigslist from a guy that bought it then read the instructions that it wouldn't work on a stroked block, my score at 1/2 price.
The intake manifold is a ls6 which I got from LS1Tech forums, came with rails and injectors and shipped for $300.
For the A/C compressor I stole an 08-13 Corvette one on ebay for $32 including mount and idler and shipping, very little tweaking on the frame (little bit of heat and a ball peen hammer in the corner for the condensor line) and it fit perfect
For the steering box I am using a 3 1/2 turn from a 85 trans am from rock auto
Here is a good link about swapping steering box's
https://www.hemmings.com/magazine/mu...s/1508711.html
For wheels I am going with old school look B&G rodder's
17x8 front with 245x45x17 and 17x9 rear with 275x40x17
After all that was done it was time to clean and paint everything and re gasket the engine and trans.
The car will be Sunset orange on the sides and black on the top so the block and trans painted to match, old school aluminum valve covers with the oldsmobile decals really make the look in my opinion, I think I am going to paint the intake manifold orange still.

Compressor fit fine but I tweaked the top corner of the cross member and frame rail joint with some heat and a ball peen hammer to give about 1/4" clearance for the lines, as far as I know the compressor is variable as i believe all newer ones are, I will be running a Southern air unit and they say their units have no problems with a variable compressor

Mauricer, where do get the frame pads and engine mounts? Probably the same mounts for the A-body Chevelles? Welcome to the world of rust!. My 64-F85 Pro-Touring was real bad-replaced the floor and trunk braces, floor and trunk pans, section between the tail lights, both doors and left front fender. All metal no bondo....Very nice job.

I looked at lots but ended up just purchasing one from ebay, welded 2 bracets on to the rad support and rubber mounted the rad

Looks like my rust repairs just got a whole lot easier, just need to get it from Wisconsin to Washington, it came from California and has been sitting in storage for years, supposedly had a little bit of 1/4 panel repair and that's all

Do you recall what headers you used ? Doesn’t look like there was any clearance issues,
also what did you have to do to mount the trans in place,
what shifter did you end up using for the trans and is it floor mounted ?

as for the trans mount just lengthened the bracket on the frame about 6" and used the stock transmission crossmember
shifter is still a work in progress as the project has been on hold for a couple of years while we built a new house and other life events that get in the way but plan on using a 2002 corvette floor shift or if that doesn't work out possibly just upgrade my stock shifter with the Shiftworks kit https://shiftworks.com/collections/conversion-kits
