confused about heads
I have a numbers matching 73 442 350/t350. I'm not building a strip car or nothing just want a good street car, not sure which heads would be the best for me. I was also told 455 heads would fit???
also had a guy offer to trade me an 86 buick century and a 94 thunderbird for my 442

If you use the #2-#7 heads, you would be at roughly 9.2:1 compression. Probably a little less.
The 73 pistons with your #8 heads and newer thicker gaskets would be about 8:1 compression.
Either one would be fine for a driver car, but if you wanted to upgrade to a bigger camshaft, you would need the extra compression.

Welcome to the board! I see you're in Gatesville, a couple of hours away from here (Dallas/Fort Worth area). Howdy neighbor!
Nice looking car, the '73's are sweet! They're a rare sight to see.
Thanks for sharing the photos, they're like candy around here so keep'em coming!![Big Grin](https://classicoldsmobile.com/forums/images/smilies/biggrin.gif)
So what other specific details about the car can you share with us? Did you get any original or factory paperwork/documentation with the car?
What color is the car? I can't tell for sure but it looks to be in a primer stage. Are you doing some bodywork or painting?

no, i dont have doc. and it is primered, yea i used to live in desoto, like the small town life lol. it has small cancer spots in quarter panels i want to fix. i need a glovebox door and front seats need recovered, i think its to quiet and would like it louder lol
#7
Ahh, desoto...that's a little closer, about 45 mins from me. lol
As you'll discover, the '73's are notorious for cancer in the quarter panels. Mind you, the '73-'77 era is cancer prone in various areas on these car so don't let that scare you. the severity of the cancer can make or break a deal, if a person is looking to venture into these years.
Depending on where your car was built, the build sheet could or could not be in a few places in the car or possibly above the gas tank.
If you were to find a copy, it would confirm which options are/were installed on the car. Including the 442 package.
What are your plans for the car? Is it going to be a daily driver...are you going to modify it...are you going to do a partial restoration...are you going for a full blown "factory original" restoration...etc..
What's the fifth and seventh letters in your VIN?

Thanks, my '73 is far from being a driver. It needs a ton of work (including an engine and transmission) but this '73 project is further down the line.
An Arlington build, you might find a copy under the carpet, behind an interior trim panel, under/above the headliner, or maybe underneath one of the rear seat sections.
If the tank has never been removed, there could be one on the tank. You may be able to see a piece of the sheet sticking out between the tank and bottom side if the trunk pan.
I thought I'd find one underneath the rear seats or the rear quarter trim panel but no luck. Maybe there's one on the tank...last time I checked I didn't see anything sticking out but that doesn't mean there's nothing there. I'll drop the tank someday and rule that location out and possibly end my search for one.
There's a chance you may not find any so be prepared.

Welcome and nice car! We love pictures!
Once you start sinking money into the car you may change your mind about making it a daily driver. I think about 9500 442s were made in 1973...I guess the question is, how many are left?
One way to make it louder is to take a hack saw and cut off everything from the catalytic converter back.

true and i'd rather pull the tank and not find it then never know, wanna sell your glove box door? lol if possible i would like to run up there sometime with my grandfather, he has a 78 calais
#15
Ahh man, c'mon...I need my glove box door to keep my work gloves safe and secure. lol
Seriously though, are you just needing the door? I may have one I removed from a parts car a couple years ago. Do you care about the color?
As far as your cowl tag goes, there's no W-29 on the tag. A build sheet is the proof to declare true or false. Granted you could thoroughly inspect the car and look for the telltale signs of the "W-29" parts being unaltered or if they've been collectively tampered with in some form or fashion. If unaltered, you could feel a little better knowing it's closer to a true 442.
However, a build sheet would be the confirmation you'd want to have to clear any and all doubts.
Post some more photos when you can and some of the other resident experts will chime in and help you with your questions. Have you checked out the '73-'77 Forum? You should join if you haven't done so already. Tell them I sent you. There are a few '73 442 owners over there as well. Also, register your car on the '73-'77 Registry, it's a free database of '73-'77 cars.
If you decide to come up this way, let me know.

How considerate of you to spare my gloves. ![Big Grin](https://classicoldsmobile.com/forums/images/smilies/biggrin.gif)
A quick and true identifier (for the 2dr coupes) are the bigger rear quarter windows and the "fastback" body/roof line. So in essence, the "442" is a Cutlass S with the W-29 package.

Im bout to put an accel electronic conversion kit on it, accel plugs and wires, and accel coil... its runnin rough. i dont think the points are workin good so instead of constantly replacing it i am gonna try this kit ive heard alot of good and bad so hopefully things will go good

Whatever you do, keep any and all parts you remove or find in the car, even if it doesn't look like an original part (if there something to be save, of course). You may need them at some point or if you ever decide to sell the car, the new owner would probably like to hear that you have the "original" parts or the parts that were with the car when you got it.
Some parts were/are one year only and hard to come by.
Hmm, can you elaborate on running "rough"? How so?

BB Olds heads do fit, but not worth the effort in your case. Your best bet is the find 5, 6 or 7 small block Olds heads. Have 2.0 intake valves, 1.62 exhaust valves, 3 angle valve job, I would mill .025 off the heads.
Be sure to check your push rod length and convert to adjustable rockers.

Bottom line is that there is no single magic bolt-on that will give you an extra hundred HP (well, except for nitrous...) but rather a lot of little improvements that must work together.

1 more note buddy much much earlier small block heads might need hardened valve seats for unleaded also installed, definitely something to think about beforehand. by the way consider a hei distributor and keep the old one and get it curved right.
