Geezer.....I'm a very firm believer that Chevrolet NEVER made a 4-bolt 327....(this is an ongoing argument that will probably never be finished) but I've never seen or even heard of one. After looking at all the casting number web sites I saw that 3955618 showed a 68-69 327 "4-bolt" for a Corvette.

I did more research and found that same casting number in the '69 302 Z-28 and a lot of 350's all 4-bolts. Then I found that casting number again for the 68-69 327 but it said "only 2-bolt". They are all large journal blocks so it would have been easy to stick a large journal 327 crank in one. Dunno, still don't think so and a couple of my engine shop friends say they have never seen one either.

OOOPS, sorry SScardino, forgot to help you, just pull the points and take them to Napa or your local GOOD parts store. If the guy's are over 50 yrs old they should be able to figure it out. If they are youngsters they won't even know what dual points are.

Thanks, I'll do that.

You might consider replacing that dual points distributor with a moder electronic unit.

ACTUALLY ...
That number means almost nothing. That casting number was used for years. There are both 2 bolt main and 4 bolt main 010 blocks. You need to read the engine ID number/VIN code ... it can tell you what the exact application of the engine in the car originally came in.



General Motors did not install the 350 in a 68 Corvette. Here are the options.
A 327 300 HP was standard ...


L36 427 cu. in. 390hp Engine 7,717 (27.01%) $200
L68 427 cu. in. 400hp Engine 1,932 (6.76%) $306
L71 427 cu. in. 435hp Engine 2,898 (10.14%) $437
L79 327 cu. in. 350hp Engine 9,440 (33.05%) $105
L88 427 cu. in. 430hp Engine 80 (0.28%) $948
L89 Aluminum Cynlinder Heads for L71 624 (2.18%) $806


Go here for the entire option breakdown

The small block originally installed in a 1968 Corvette would be a 327. Either the standard 300 HP or the optional 350 HP.

I had problems tracking the VIN# It was originally registered in Oregon. I'll do another search.

Thanks,

Use the same points as a single point distributor, times two.

Look at the driver side front of the block for the "suffix" code, it'll be the letters at the end of a line of letters and digits. The suffix can be one, two or three letters.

I have a block that has 3970010 as the casting number as well, and from what ive seen it could either be a 68 327, which came only with a 2 bolt main, or a 69-79 350 which came with a 2 and 4 bolt main. So if its a four bolt its deffinately a 350, but if its two bolt you could be in the same boat as i am. I have been searching for two weeks now trying to find out if i have a 327 or 350. Still dont know...

What are the codes stamped on the pad right in front of the passenger side head, on a flat pad that sticks out from the deck surface just above the passenger side water pump leg mounting position??

As you have found, the casting code only gets you so far, now you need to research the stamped application code to define what you have.

Thanks for the info. Your right, I have he same trouble on the running gear. And, obviously the motor.
