I do know it's not the original one. I don't know where it came from the car came like that. But I know it been replaced at the past.
I cant recognize the engine if it's 2 bolts or 4 bolts or even if its 327 or 350 (last owner claimed for 350) Plus I'm not that familiar with GM engines history.
I added a pictures of all the numbers and letters I saw on the engine.
If anyone can supply me with info he knows and can light me up I'll appreciate it!
i search anywhere for numbers and letters and that is what I got.
The point you are pointing is the alternator on my engine.
I don't remember any thing behind that (that's way I didn't take a picture) and on the other side engine head there's nothing (visible at the picture)
"Counter Exchange" (or Chevy Exchange depending on who you talk to). A warranty block. On the stamp pad Alan is referring to there is a sequence of letters after the partial VIN number called a "suffix". The stamp pad could have the original suffix (that tells you exact what engine it is and what car it came from, Google the letters) or a "CE".
Where's the cast date is seen?

OK and you said it's 350 unless it's a CE block? Why unless it's a CE block?
is the round yellow mark under the alternator represent where it should be stamped? cause I don't remember anything visible there.
Yes. But the stamp is typically removed when the block is decked so if it has been machined prior then you will not know without looking at the crankshaft part number or measuring the stroke through the spark plug hole.

So it probably 350 2 or 4 bolts that might be otherwise unless I'll open the engine. There's no way to know from the outside?
What exactly should I check? Crankshaft casting number? Engine head casting number?
The only thing that is for sure that the cast day is April 10 1969.
If it is the 350 how much power will it be able to carry?
any idea about the power it should have and how much it will carry?
450+ horsepower.......impossible to know more at this point unless you crack into the engine.
With an April 69' date it is most likely a 350. In 69' the 327 and 350 used the same block....GM made a large journal 327 crank to fit in the 350 block. One year only. But like I said.....you will have to get into the engine to know for sure. Somebody went through a lot of trouble to detail it up nicely.....
If you going to modify it anyway...pop the heads off now and know for sure.

ISRCamero. This is really too broad a question to answer effectively.
A stock C3 Corvette 350 can be anywhere from 165 to 330 sae net hp. You need to provide the stamp pad suffix to see how the engine was born.
What HP does it have now? Who knows? Until you open it up and let us know the cam, heads and CR it could be anything.
How much will a built 350 support? Generally speaking, north of 400 and have it still be civil/drivable on the street. Around 450 if you can live with reduced drivability. Once you get over about 400 hp you generally have to compromise by moving the rpm up higher, which leads to it being "less civil".
How much hp will a 2 bolt main block support? That is more a function of rpm than power level but it is not uncommon for a 2 bolt to survive at 400 hp at sane rpm levels, more with improved ARP bolts.
Here are a couple of recent threads on the 2 bolt topic.

Building SBC engines has been around for 60+ years so there is a TON of info on the interweb. Google is your friend.

Hi guys
Thank you for all the info.
I'm not an American so I'm less familiar with 350 engines. This is my first one and I'm trying to get as much info as I can about it since I'm not even sure it's a 350 and not 327 or where it came from.
I'll probably open the engine at next summer so it will take time. Just trying to line between the dots.
Hi IRS,
Have you looked at the pad?
The pad WILL still be there.
Chances are 50/50 or better that the stamped engine assembly information... date, cubic inches, and original horsepower, will still be there too.
What the engine was originally doesn't become a mystery until you determine that the pad is currently blank.
Regards,
Alan

By the picture you added it looks like under the alternator base. Am I right?
yes, in this thread you have been given 3 separate pictures showing you exactly where to look. One picture with a big white finger pointing to it, one picture with a yellow circle around it and the last close-up picture.
