I'd like to buy a truck but I don't know what is the engine. Anybody are able to identify this engine?

berencam · 11-06-2007, 02:40 PM

grab the numbers off the back side of the block, think its on the drivers side just behind the heads. if i had to guess, id say 307 or 327

royo · 11-06-2007, 02:57 PM

No I'm not able to see at rear of block to ck number and I don't have any num on front of the block on the passenger side. I have take a picture of the front of the block between block and water pump. The front of the block is not straight. And the oil filler neck don't pass true the intake manifold. Check this pictures!

lukecp · 11-06-2007, 03:06 PM

That is most definitely NOT a Chevy engine. It is some sort of GM engine (it has an HEI distributor in the back), but I have no idea what it is. Probably some type of Buick, Olds, or Pontiac engine (I believe Caddys has a front-mounted distributor).

**FRENCHBLUE72** · 11-06-2007, 03:16 PM

correct most caddys that I have seen have the dizzy up front Id have to agree with c-downs and royo both very knowledgable guys and c-downs is very into the old time rods..

eedgell · 11-06-2007, 04:01 PM

Not a chevy v-8. Maybe olds or pontiac, buick. Looks like a big block maybe with the spark plug spacing. Or are all the other gm v-8's plugs spaced like a big block?

woodridge · 11-06-2007, 04:06 PM

It's a 77-80 350. Check out this site.

manimal · 11-06-2007, 04:08 PM

Thats an OLDSmobubble. FOR SURE. The oil filler and water neck give that away. So does everything else about it. What is it in?

syncrov69 · 11-06-2007, 04:21 PM

Hi woodridge why you say that's a77-88 350, I'd don't make the link on the site taht you give

hvychve · 11-06-2007, 07:10 PM

I would say oldsmobile also , without better numbers, hard to tell what year and what exact size,

67_C-30 · 11-06-2007, 07:23 PM

Its a mid to late 70's Olds 260, 350, or possibly 403 judging by the GM Corporate Blue paint. The only I know absolutely without a doubt is it is an Olds engine.

Jtrux · 11-06-2007, 07:34 PM

Valve covers are another give away.

**jerry moss** · 11-06-2007, 08:11 PM

i agree, it's an oldsmobile motor.

ChevLoRay · 11-06-2007, 08:13 PM

My nephew had an '80 diesel Chevy, and pulled that engine (Olds based) and replaced it with an Olds V-8.

What truck are you looking at. I haven't seen anything in any comments about what it is. Is it possible that it was originally a GM diesel? Knowing what you're looking at may help you know why the engine that's in it, is there. Another clue may be a second battery mount that doesn't have a battery....etc.

I wholeheartedly agree that it's an Olds engine.

67_C-30 · 11-06-2007, 08:16 PM

The truck is a 67-72. You can tell by the heater box and master cylinder!

Cyclone44 · 11-06-2007, 08:17 PM

It's an Olds for sure....George

syncrov69 · 11-06-2007, 08:24 PM

Woddbridge have the right answer after decoding the casting number it's a 557752 3b block=Olds 350 from 77-80 year. Badly I'm looking for a chevy 350 not olds, parts appear to be difficult to found if you compare to Chevy. The truck is a 1967 long stepside fluo green!! Thank's for your research.

woodridge · 11-06-2007, 08:26 PM

I didn't have much time to fill in the post after I found the casting # on the site I linked. It is most definately an olds engine and the casting number ID's it as a 77-80 350.

2A '75-'81 260 Solid main webs for 2A's only? At least for '76.
2B ??-'81 260 557751 Windowed main webs. Windowed main webs for 2B's only?
3A '79 350
3B '77-'80 350 557752

bill8333 · 11-06-2007, 08:49 PM

I agree it's an Old's engine I had one of those in a 442 i bought way back when.

Jtrux · 11-06-2007, 09:18 PM

I've seen a couple of them in 6 7-72 trucks before. A junk yard near me had a real clean pick up and when I lifted the hood, there sat an olds motor. I've seen one other also.

woodridge · 11-06-2007, 10:43 PM

The K-2500 in my avitar had a 455 in when I bought it. Normally, these are killer motors but this one ran like a dog and always hot. A 400 small block now resides under the hood and runs much better.
