    My buddy went a bought an 89 camaro because it was advertized that it had a 327 that was completely rebuilt and trans that was completely rebuilt. They supposedly only have 100 miles on rebuild. We are both around 19, and his mom told him the car had to be gone tomorrow. Im wanting to buy it, but I wanna check one thing. The guy said the motor came out of a 1969 camaro. Could this be correct? He put an electric pump on it, but its still carbed. Could this be bad? The guy also said he was going to and it would probably need electric fans on it before it got warm. How can I tell for sure what engine it is. I wanna make sure it wouldnt be a 305 bored to a 327. Also where do i look to see which heads it has on it. Sorry for the long post, but if its a 327 I wanna drop it in my jeep.
    Thanks
     
  2. Google Chevy engine I.D. Get all the numbers you can off the block, the website will show you where to look. Electric pump is OK, but the electric fans worry me a bit, It shouldn'd have a heating issue that bad unless there's something else wrong with the motor......

    Casting number is on the driver side near the bell housing... match that number up for the engine, then pull a valve cover off and match up the casting number there to the head numbers. They both should be a six digit number.
     
  4. 19......good for you to start so young and actually do some research !

    What is the number on the rear of the block on the driver side.

    3782870,3789817,3852174,3858180 are all 327's62-64
    3782870,3789817,3858174,3892657 65-67
    3814660,3914678,3932386,3955618 68-69

    Good luck ! They can be bored out .060 with no issues. great lil motor and my favorite next to a 406 sbc

    ill check all that out..what is the motor worth? I can get the whole car for around 500...The guy was gonna drag race it so maybe that is why it was needing fans? My buddy doesnt know jack about vehicles so maybe he just thought that..Im not sure. The motor is very clean lookin. Also, could this actually be a 327 if it was outta a 1969 camaro..Ive been into old cars most of my life but never got into the technical stuff, but now I am.

    In '69 the base V8 motor would have been a 307 with the option of a302, 350, 396 or rare but possible 427. in '68 the base V8 engine was a 327 but in 69 they switched to 307 the best clue would be the stamped number on the pad in front of pass head and the cast number on the block in the bell housing area

    Never was a 69 327 engine.....
    In front of the passenger side head the block deck has a pad that has some numbers followed by some letters...get that and the origin of the block can be deciphered. For the heads, remove a valve cover and get the casting number.

    I was told that the block deck stampings were not as reliable as the casting number in the bellhousing mount.

    Just run the casting numbers on the head, or cheap the casting shape in the front of the head. If they are double humps, doesn't mean they came on that motor!
     

  11. Most 327s had power pack heads. Very few were sold with double hump heads. But the heads do not make it an engine they can be changed and that can be done very easily.

    if it was an engine over bored to be a 327 it would have been a 307 bored .125. A 307 is basically a 283 with a 327 crank. Someone is going to say that is not true but they are wrong, so lets get that out of the way before we even start.

    It is possibel that it is out of a '69 Camero but it is also possible that it is out of an impala or a truck or a chevelle etc. Once you take a wrench to it the origin of the block becomes a mute point. You are young and this is a good time to learn this, the origin of an engine is not impressive, be impressed by how it runs.

    As has been mentioned look on the back of the block to see what the block is, the numbers are right there on the top of the drivers side. In '69 it would be a large journal engine so all it would take to make it a 350 or a 327 is a crank change.

    Good luck, become a good detective and you will not be disappointed with what you buy.



    ". . . 1969 was the last year for the 327 and by then there were only two models produced that created 210 and 235 horsepower. Today, engine parts for this motor are plentiful and can be found at any reliable auto parts store."

    I guess I could also quote Chilton's but my older Chilton's is borrowed and the one I have in the house starts @ '71.

    The 3970010 blocks were used to build 327 or 350 It just depended which crank they had from the factory. I would guess there are other casting numbers that were also built in different CI sizes.

  15. You can check the numbers from the side of the car unless it is set way back, still can normally be checked with an inspection mirror.

    My experience in '69 that the most common engines were an inline 6 (something that I don't want to know much about) a 307 or a 350 in a Camero. Some genuine Z-28s had 302s in them, but there are more '69 Z-28 Cameros today then GM ever built.

    If I bought the engine I would tear it down for inspection if it is truley a rebuilt engine all it will cost you is a gasket set and if it is not you would want to know wouldn't you?

    I personally would be a little leary of a second gen or third gen camero with a 327 in it. It is just not a common thing to do. Never the less even if it turns out to be a 307 it can be built to perfom on modern day pump gas and if you really want a 327 all you need is a 350 block and use the 307 innards. 350 blocks are cheap and plentiful. Note you will need to change the pistons.

    I have a 307 here that is a good runner, I got it cheap and if it wasn't any good that was what I intended to do with it.

  16. Untrue. You could get a 327 early in the '69 model year. The 307 came along at mid-year and the 327 was discontinued. One of the saddest days in GM's history in my opinion.

    For codes, here's the breakdown:
    Powerglide: FK
    Th350: FL
    3-spd: DA
    4-spd: DE

    If the flywheel is off, a look at the crankshaft flange will tell you if it's a 327:

    I stand corrected...Pornnbeaner is right, there were some 327 large journal cranks in 69. Usually, one thinks the 327 ended in 68.

    Letter codes on blocks are very positive identification.....the list of codes on the web sucks but the MSA-1 book is very complete

    Check out the casting numbers and partial VIN on the engine. They'll tell you what you have.

    On the block: Check the partial VIN stamped on the machined surface on the front right side where the head mounts to the block. I have V0614HF
    Indicating a 327 built in Flint, Michigan on June 14th, with Califonia camshaft, mated to a powerglide for a passenger car.

    Large numbers behind the left side head--these numbers will get you in the ballpark.

    On the heads: Pull the valve covers. The casting number is located between two valves.

    My pics show a 1967 327 and 202 heads.

    Once you have the numbers google them with key words Chevrolet small block numbers or Chevrolet Small Block Identification.

    double post! Wow...go do some laundry in the middle of posting and everyone's already answered. Nice!
     
  20. The stamped codes alpha numeric is a good place to see what the engine was actually intended for if not what it came in. Sometimes corvette engines came in Caprices etc. Not common but it did happen on occaision.

    In the case of the engine in question if one really wanted to know if it started life as a 350 or a 327 the alpha numeric code stanped on the front of the engine should resolve that issue.

    Check the numbers on the deck that were stamped on the engine right before it went into the car. Look up the 2 or 3 letter suffix to find out what it is and what it left the factory in. Not all engines have these numbers.

    The engine in my roadster could either be a 327 or a 350 just going by the block casting number. Going by all the other clues it is an LT1 but it must have been a crate motor because it doesn't have the appropriate suffix codes which were stamped at the assembly factory and not the engine building factory. Casting numbers can be misleading and won't tell you the HP rating. The hand stamped number on the deck will.

    327s never came with "power pack" heads. High performance yes but true power pack heads were for the 283 engine. The 327 heads were always referred to by the HP rating that they came on...340HP heads and 365 heads with the 2.02 intake valves. The power pack heads were really not sought after in the 60s unless you were restoring a Corvette or a 57 Chevy and you wanted the #s to match.

    Sorry it's just a pet peeve of mine when people call H/P 327 heads "power pack heads". To me it's like calling a 57 Chevy an Impala.

    Jeep?

    are you sure you didnt mean to say Hot Rod?

    run the pad numbers infront of the passenger side valve cover, they are stamped on a flat pad..the casting number out back is not difinitive

    also if it needs electric fans to run on temperature, theres other issues.
    these engines were fitted with a 4 blade steel fan off the crank pully via belt to the water pump..never needed electric fans on them back than, and still shouldnt need them..that is like I said if there isnt a problem with it

    Oh and be ready to rebuild it..

    Not sure if it actually needs it. I wouldn't c why the fans would b needed. He was gonna drag race the car so i don't know if that would matter. I'm actually just buying to resale the car. Or keep the motor. I'm just debating. I'm gonna teat drive it and go from there

    I gotcha now. Ill check and make sure it does have the steel fan. If not I may steer clear. I'm not sure if my buddy came up with that or what. He is not mechanically inclined what so ever
     

  26. I'm thionking that in the '89 Chebby it needs an electric fan becase that is what they came with. No fan shroud etc. Probably not wired in to the race car yet for lack of knowledge.

    Ahh good point boss, I didnt catch that
     
  28. I agree. It's easier to just go by the last 3 numbers of the part number, or if you want to be really generic, by the casting shape on the front of the head.

    Just to validate. A friend's dad (a dentist, btw) bought him a brand spanking new base '69 Camaro, 327, 3spd, puke green. Would have been an early one. Logged many miles in it, myself. Though probably considered fairly rare today, there were some built.

    Check the pad in front of the pass side valve cover, as others stated. Best way to varify what's what.
     

  30. Hell I'm just makin' it up as I go. Sometimes you get lucky with your best guess. ;)
