not sure on info, but...

I'm not real sure on where to find info or what info you actually need. A pal of mine took a 455 out of a 70 something Delta 88 and dropped it into a 70 something yellow cutlass. I tell you that car was a highway monster. In my opinion, and depending on application, it's a very streetable motor and worth your while. Good luck with it.

Olds455 is a torque monster & worth building. There are BOP TH350 & TH400 also TH350 with Unibell which fits Chevy & BOP

id look for a 68-70 455 block look for a set of C casting heads (dont waste any money on any other BBO heads ) , they are the best... if i remember correctly they are some with forged steel cranks (good luck finding one)


after 72 i think they start to make the blocks with windowed mains (JUNK)

get you a built up 200 r4 so u have that over drive on the high way


yaya i know the 200 r4 are junk when power is put in front of them stock ... but there a dream if u get get one built

First, Buick, Pontiac, and Olds all made 455s and all are completely different motors. Different castings, different bore/stroke, absolutely no interchangeable parts (except for the distributor cap and the carb).

The Olds 455 was made from 1968-1976. All 455 blocks have solid main webs. All have cast nodular cranks except for a minuscule handful made very early in the 1968 model year. Olds changed CR with piston dish, so except for the rare "D" casting heads used on 68-69 W-30s, all big block Olds heads have the same 80-ish CC chambers (usually about 84 CC as cast). The 73-76 "J" casting heads are the worst-flowing but the most common. They can be ported to flow with the best, however. Edelbrock heads help a lot.

What else do you need to know?

Joe...you forgot to add...they are a very well built engine. I'm a really blue-blooded Ford man...but that was one fine engine.....I like the Olds.

i've been thinking that i need to put a 455 in a 26 essex i have, a couple years ago, in high school i bought a 73 delta 88 land yaught, for $150, that was the funnest car i've had. for some reason it went through tires as fast as gas.

so i should look for a pre-73 engine, if i cant find one pre-73 i still have the engine out of the delta. and you sat the 73 455's are fine just need older heads or a good porting.

so now on to the tranny, did the uni-bell th350 come in any production cars?i don't want to use a th400 because the only bop th400's i've seen are like 27ft long. and th350's are CHEEP! and wasn't there some thing different with the bop tranny's torque converter, something like variable pitch, but i might be fowled up. im not a 100% sure yet on what i want to do for an engine, i would kind of like a nailhead, but im having lots of trouble finding one, and i have a 455 so i don't know.

thank you.

If overall length is a consern, the th400 came in a shot tailshaft version.about 5 inches shorter than the one that you pulled out of your delta (actully a th375)

There was a variable pitch torque conveter in the th400, but, it was in the early to mid 60s. 64+65 iirc

with the amount of torque the 455 puts out i'd go with a th400. unless your going to build up a th350.

TH400 came with 4",9" or 13" tail. TH350 came with 6", 9' or 12" tail. The Unibell TH350's are hard to find now, BOP TH350 & TH400 are still plentiful.
BOP bellhousing looks like this at top center \___/. Chevy looks like this /\.
I have a built SwithPitch short tail BOP/TH400 I'm probably gonna throw on Evilbay.
