Hi,
I have a 1965 Chevy Impala Convertible that has unfortunately had the motor changed and is currently running with a 305 motor. I have a chance to buy a 1966 dated 327 with 4-bolt mains and camel back heads that originally came out of a Chevy Chevelle Malibu. Even though it will still not be the original motor and is a year later, it will be more period correct. The car has been restored to factory original. Since this motor is still not the original, will it add any value to the car? What can anyone tell me about these camel back heads? The guy with the motor will overhaul it and install it and figures the price tag will run about $2000. Any advice??? Thanks.

Randy

my opinion, No, as its just a 65 impala convert with a 66 327. 4 bolt main.
If 305 runs good, just enjoy it as it is now , unless u want more performance ? :anim_25: and keep us posted

Randy.....Someone will correct me if I'm wrong....However, I don't believe Chevrolet ever made a four bolt main 327

 

[petes83usa]

I thought the 327 truck motors were 4 bolt blocks ....:confused0006:

 

[mosthuman]

Four bolt main caps are 350 and 400 cubic inch only. I always get a chuckle when I hear 327 four bolt main.

 

[mosthuman]

Oops, forgot to specify small block.

 

[solanistec]

The only was you could have a 327 with 4 bolt main is to use a 350 block and a 307 crank. Then it would be a 327 with large main journals. As for a 66 motor in a 65 it would be a closer year match for the car but it will never be a numbers matching car. If it was a factory camel hump head 327 it may be a 350hp motor. And it would be a lot more fun to drive than with the 305.

Chevy never had a 4-bolt main 327. I had a guy try to sell me a 4-bolt main 283 out of a '59 Chevy firetruck one time, I just laughed and walked off.

 

[oldcarnut56]

I have a 283 I pulled from a 65 Impala SS 2 brl carb and nothing special heads. It probably won't help the value much, but just saying I have one. motor is torn down and needs rebuilt.

Interesting. I've known this guy for years and he is a straight shooter and a fine mechanic. When I asked him about this motor, all he said was it came out of a 1966 Chevelle Malibu, it's a four bolt, he has the camel back heads for it and it's kind of a rare motor. I don't know alot about these engines, so I'll have to question him more. He did say it had fuel injection heads on it now, but that I wouldn't want them because then I would have to burn premium gas, so maybe he previously worked it over and made some changes???? Like I said, he is a straight shooter and he has no reason to tell me it's something it isn't because he's not really trying to sell it to me, I approached him about it. I don't really care if it's a 2 or 4 bolt, I'm just looking for something more period correct and that was actually offered for my Impala.

To upgrade, do a 396 or 427 for the extra money. That will add some value, interest and fun factor.

 

[Rick_L]

If the guy is being a straight shooter with you, then he just doesn't know better. No 327s were ever built with 4 bolt mains. It's possible but doubtful that the heads have the big 2.02 intakes also. More likely they would have the 1.94" intakes.

 

[100%Chevy]

I'd like to find an original 250 h.p. 327 for my 65 myself(It's a Caprice and only came with the 327)!And the correct 275h.p. 327 for my 67 Impala.They are not rare at all.Nor are they expensive.
I have a couple correct year 283's,but not what I want.
No 327 had 4 bolt mains and double hump heads are pretty out-dated now too,compared to whats on the market today and the cost of re-building older heads.
Go to sites like Racing Junk to look for used,modified and re-built engines if you want the correct numbers for your car.
For $2000.00,you should get receipts and proof of the machine work and parts used to verify the build.
I just re-built my 68,327 and none of the parts were hard to get or expensive compared to any other small block Chevy.
Mike.

 

[Fift7BelAir]

Well, I'm just going to have to get more info. The guy has been around GM engines for years, and is definitely a GM guy so I would think he knows what he's talking about, but I'll have to dig a little deeper.

 

[Typhoontx]

The only way it would be a 66 block and have 4 bolt mains is aftermarket main caps were installed sometime in the past. The only other unlikely probabililty would be it was some kind of r&d prototype that somehow made it out of gm's doors, If that could be proven with written documentation then you might have something there

327 4 bolt mains it must be some rare factory expermental thing. In 66 most of the hump heads were on the fire breathing 275 hp monster. 1.94 & 1.50 valves still a nice moter but nothing special.

camel heads

Thats a bit much to put in those heads, especially if they are not the ones to match your car. 2000 dollars!!!

large journal 327

Chevy did in fact build large journal 327's in 68& 69 ( I have a fresh 1010 crank in the basement.) after they had came out with the 350 four bolt blocks for transam racing. RPM during road racing probably had as much to do with introduction of 4 bolt mains as anything. I can think of .orginally trans am cars could only be raced as factorys built them with 5 liter engine limit hence Z-28, Boss 302 etc. We offset ground these cranks tonget closer to a 317" cube limit.

USA1 aren't you forgeting the 350 horse 327 chevy2 like grumpy's and the 325 horse 327 malibu? Both winners in my book.
These were both 2.02 valve motors

I may have what you are looking for a 250 or 275? remember how to tell these apart I don't . This is the motor in my 56 when i purchase it in 87. If i remember correctly it was a 65 cor vette code motor appearantly intact. stamped FIIO5CD. with afb intake. hasn't run since I drove it into the garage.
