1955 Super 88 Build

I have a 1955 Oldsmobile Super 88 2dr sedan which ironically i bought off my dad in 2022. He bought it in 2015, he drove it, radiator hose blew and he parked it until i bought it. He did have the motor and trans rebuilt but those sat in waiting. Youtube has alot of great videos of 54-56 but its mostly complete products or "for-sale" videos. There are alot of parts missing, it was an A/C original but I cant seem to find any of the parts to it, I guess my dad lost them. The car is an original Texas car built in Arlington where I grew up, kinda cool. I will post some pictures of what I want it to look like and some of the things I have done so far.

Good luck with your project. I'm hoping you get motivated and keep at it. I don't have that era of experience to offer much help other than encourement.

Pictures would be great for us to see and offer ideas and guidance.

AC in a 55?

I'm good with tools, building things, taking things apart to see what makes it work has always been my thing. I had a 1966 C10 in high school that my dad and I bought to work on together before I could even drive, I stupidly sold it instead of getting a second job to get my kids Christmas (good cause but I could have put in more effort). Working on it was cake due to the fact there is so much reference material and parts you can practically build one from scratch, plus my dad helped a lot. Forgive my rambling as I felt some backstory was needed. A few of you have always said the dumbest question you could ever ask is the one you never ask at all.

I need help, I have a 1955 Oldsmobile Super 88 2dr sedan which ironically i bought off my dad in 2022. He bought it in 2015, he drove it, radiator hose blew and he parked it until i bought it. He did have the motor and trans rebuilt but those sat in waiting. Youtube has alot of great videos of what I like to call the Tri-Olds (54-56) but its mostly complete products or "for-sale" videos. I am sorry for offending some of you but this one will not be all original, I cant afford that and its just not me. There are alot of parts missing, it was an A/C original but I cant seem to find any of the parts to it, I guess my dad lost them. The car is an original Texas car built in Arlington where I grew up, kinda cool. I will post some pictures of what I want it to look like and some of the things I have done so far. I will also ask more specific questions like what do the trans bolts look like to bolt it to the mounts.
If your not going to use the AC parts PLEASE preserve them for the rest of us. The parts are rare or near impossible to find. Please save it ALL for the rest of us.

Thank you

Welcome to the site! That floorboard looks incredible! Every one of this vintage I've come across has rot in the floorpan.

Your picture of bolts didn't come through. Would you try again? John

Engine

Well I figured it out I think, and it's finally in the car (boy was that fun) I had the crane fully extended and still didn't reach far enough. Used different bolts and holes on the heads and intake with the crane, I just didn't like the carb studs with this massive chunk of iron.

I agree there's a lot of weight between the two! Having the front clip off was the way to go. John

I found it easier and got more "throw" by using the engine leveler bolted to the heads without the intake, and then just install the intake after in the car.

That's what I resorted to. Thanks for your website, I've been using the pictures to figure out what I'm missing.

The manuals call it a baffle for air circulation. The type R (slant pan) Hyrdramatics didnt have oil cooling. Unless you drive it all day in the summer in Phoenix you should be good. LOL
Note: The Jetaway adding cooling lines in 1956.
