 My bad,  Just looking at a small block casting site, it should be (correct me if I am wrong) F Flint, 1 Chevrolet, 009s is the production sequence number (I think) J October, 8 8th day, 8 model year of car 1968.  3782870 is a 2 bolt cap block made from 1962 - 67.  Car, truck 250 hp to 375.

 

There should be a pad at the front of the engine on the passenger side where the head sits on the block.  There will be a small flat pad there with numbers stamped into it.

Well, technically the 870 blocks are likely the same, hi perf or not. There are no 4 bolt main small journal 327 blocks, so whether it came from an injected Corvette or a Biscayne station wagon, I am betting the block is identical other than the stamping (which is not there!)

Should be, so it would be from a 1964 model car of course.

Well thats great news my car is a 64 lucked out on that numbers matching when theres no numbers lol ..kidding its a driver Thank you guys so very much

I don't think it would have a vin in those years but normally it would have had a suffix code after the date stamp showing what it was installed in. But, as with a lot of things in that era, there is a good chance it got missed.

250 HP 63's were not stamped, 300HP was stamped with partial VIN. It would have come from a US Chevy and the S makes it a full size Chevy 250HP with powerglide I think.

For 1963 and I assume 1964, the following information would be true:

Check the heads, they would be camel humps if a 300, triangles if a 250HP. 2 inch exhaust manifolds if a 250HP and 300HP had 2.5 inch. 250HP had a rochester 4GC and 300 an AFB. Change the heads, exhaust manifolds, and carb and you have a 300, they both had the same cam.

it looks like a date code to me with S being the suffix code  F  asembly plant then 1009 being October 9 th the next day after being cast If that's possible the S for suffix code. Like don said 250 hp engine .  The date codes I have seen all start with assy plant then a four number stamping for month and day Followed by the suffix code. Codes starting with S are shown for 62 to 64.

Thanks guys with all things being the same I will check the heads and that should help ? great site fellows!

Hi guys been thinking ,,car has a 283 in now from 67 factory maybe 190 hp ? added a 4 bar carb so maybe 200,,IF my 63 327 has only 250 hp putting the 63 327 heads on my 283 would it not be darn close to the 250 the 327 might have..? be alot easyier to change heads than pull and install motors ? whats your thoughts and pros and cons ?? Thanks once again guys

I have been told that ..would not the added comp from the 327 heads not improve low end on the 283.. it runs real nice but yep power is lacking
