OLDS Engine block codes...

[beretta]

having some trouble finding out what this engine is, ummm.. its out of a 60 something.. i think 65.. cutlass convertible its my dads, its rough as hell but he picked it up cheap and parting it out he pulled the engine out today and wanted me to find out what it is.

The block casting number is... something ... LOL

4 8 5 4 2 6

My dad said he found some numbers online but couldnt match it up, he matched it to 4 8 5 4 2 8 which is a 455.

And im pretty sure the last digit is a 6 not a 8.. he sent me a picture as i havent been to the shop yet to look myself..
if anyone knows where to find casting numbers let me know or if you find something online if your bored..

Try asking at Classic Oldsmobile

well i might have found some info but no casting numbers just yet..
the 455 was made between 1968 to 1976...

Im pretty sure the cutlass is a 65 or 66.. i know dad was saying something about the floor pans are the same as his 65 chevelle and alot of other parts are the same as well. im not sure what years were the same i have no clue lol.

Im pretty sure its a big block and thinking its a 442... 365 horses is the stock rating for the 442..

I only looked at it when there was a foot of snow on the hood and was getting dark so i didnt get a good look. i know it had a big crappen holley double pumper on it though, it looked pretty close to complete, it was missing the rocker covers i think unless they are in the car.

Who even knows if its the original engine LOL. im sure theres date codes on it some where. maybe its even just a 350. dad scrapped a car back in the summer with s 350 olds engine and i think he had it running too.

If thats a 442.. i think it would look nice under the hood of my firebird LOL. he had the car listed forsale complete but only had a couple time wasters so hes parting it out i think now. he even has the ownership for it and i think its a 1 owner car its been off the road since the 80's, It was the guys fathers car and he had a couple other shet boxes and had to clean up and get rid of them cuz the township was after him for the cars sitting there i guess.

very interesting info...

According to my trusty Olds engine book, the 455 was available in 310 hp, 320 hp, 365 hp, 370 hp, 390 hp, all street engines, with full manufacturers warranties. The 455 is a very forgiving and long-lasting engine. To eek out more HP you can go with higher compression, which will prevent pump gas usage (highest stock 455 comp. was 10.5:1). To achieve this, use flat top pistons (butterfly cut), milling heads, and decking the block. This will yeild CR in the 14 range. However, you have to pay for it in wear and tear.

I bet this those old engines would haul some serious BUTT. if you put some money into them.. what could it even run on at 14:1 compression LOL... the highest pump gas we can buy here is 94. prob need to run it on alcohol ..

I think i need it for my bird. im gonna talk him into holding onto the engine if hes parting the car out lol. Its rough but could be fixed, the front floors i dont think are bad, the rear is screwed and the trunk pan i think is going. not sure what the frame is like i never looked under it, but the body looks pretty solid and there is no dents in it. the roof is mangled but all the hardware is still on it.

well.... what do ya know its not a 65 LOL. and i found his ad for it online...

its a 67.. so... im going to guess its not a 455 since they were not made until 1968.. unless its not the original engine, so its either a 400 or 442, i think i did read somewhere the big block engine block codes were at the front about the water pump and looks like thats where this one is...

In the back ground that was a 65 ford convertible. with the original 289 engine and it was running a year ago, not seized so i assume it prob still runs. also stripped it to part it out. we cut off all the area's with vin numbers stamped

The olds.. only has a 10 bolt rear and im pretty sure its not even a posi or that would be coming out for sure lol

edit... hmmmm well looks like he has it online forsale already and im pretty sure its not even a 455 LOL.. and looks like it stripped it down a little musta got bored ..

442 was a car and not an engine. 4bbl carb, 4spd and 2 doors. Engine could be a 400 or even a 350. They are a 60 degree block, so only bore and stroke will tell.
Bore looks stock and the engine is well used.

i was at the shop today and was looking at it, its not the original engine from the car thats why he took it out to sell separate, its a 455 for sure. and its already sold guys coming monday to get it. and i think he sold the car too.

I can look this up in some Olds books that are at my uncles shop. The 455 didn't come out until 68 in a cutlass. The earlier motor was the 400...which is similar. 455's were used in boats....specifically jetprop boats through the 70's. On Olds motors you need to look at everything. Manifold, heads, exhaust manifolds. The block is only 1/4 of the story. You could have the same block but a different trim or model could have different manifolds, heads and even the intake. You can tell right away between the 350 and big block olds by the manifold width.

send or post motor photo's.


Is that the 1967 you are parting out. Does the car have a/c. Let me know..i am interested.

I am working on my uncles 67. I convinced him to turn it into a Corn Fuel Burner and switching back to the high compression 400 block.

[beretta]

hmmm the engine was not original engine was date coded 71 -74 and was a 455, engine and trans is sold guys picking it up tomorrow.

The car is still there at least it was yesterday, someone is interested in it and i think going to look at it or maybe he wanted it for sure i dont know, its my dads hes selling it.

Also im in Canada Ontario, dont know what it would cost to ship a whole car lol. it is very rough but its all there, the rear bumper is screwed the corner got bent when it was pulled out it was sitting tight to a fence or something, and the front bumper is really rusty and the floors are not great. pretty rusty, but its all there and i think the fenders and inners and stuff are solid, pretty sure its pretty much complete though, the center console is really good shape, dad was going to keep it for his chevelle and put buckets in it but i think hes going to keep the front bench in that car. the dash i dont think is too bad would probably clean up decent. handles and trim and stuff is all there. pretty sure it was a 1 owner car, the son had it but i think his dad bought it new and not sure if it was ever switched out of his name.

if your interested in anything from it reply to the add in my above post, its my dads..
