Why couldn't this be the engine for this car? The casting number says its a 327 between 62-64 the engine stamp is Feb 28th and vin on car is April. So what I'm I not seeing here?

Because the "S" suffix code indicates it came from a 1962 327 w/ powerglide, full size passenger car as posted above.

It might be possible, if it just had an automatic and another letter added after the "S"



Good luck... GUSTO

Maybe the HP just didn't get stamped on

emccomas

No.

The engine pad is missing the correct Corvette engine suffix code, AND it is missing the VIN derivative that ALL Corvette engines in this year had.

But, not all passenger car engines had a VIN derivative stamped on the engine pad.

Passenger car engine VIN derivatives started with just the high performance engines in the early 1960s. By 1968, all Chevrolet engines had the VIN deriivative stamped on them.

Note: In case you are wondering, the 'S' in the engine suffix code has NOTHING to do with the 'S' that is part of the VIN.

S was used on 1962-1964 327, 250hp engines with a powerglide and installed in a passenger car.

Its weird that the replacement engine is the correct year and month. What are the odds

provette67

As someone who has sold a few hundred blocks over the years the odds can be better than you would think.

I am not sure how "correct" I would call the dates.

1964 Corvette #15866 was built on April 17th, 1964.

Typical time lag between engine assembly and vehicle assembly is 2 to 6 weeks, and two weeks is more realistic than 6 weeks

The engine was assembled on Feb 28. I am assuming the date code will confirm that this is a 1964 block, and not 1962, 1963, 1965, etc.

The time lag between (Friday) Feb 28, 1964 and (Friday) April 17, 1964 is 7 weeks.

It is certainly "possible", but it becomes more improbable when you add it all up.

Now, if you car is a powerglide car, this engine could be "made" to appear to be a correct Corvette engine for your car (with a bit of work).

My guess is that was probably done intentionally........

trying to create the partial appearance of an original engine.

According to the three sources I use for SBC suffix identification, the "S" suffix was used ONLY in 1962. The OP should also post the casting date, but I am reasonably sure that will confirm this is a 1962 block and, as previously stated, is a passenger car application.

Here are the other suffix codes for 1962-64 327 engines that begin with an "S":

S 1962 327 250 - Powerglide
SA 1962 327 250 - Powerglide, a/c
SA 1963 327 250 - Powerglide, a/c
SB 1962 327 300 4 h/p, Powerglide
SC 1962 327 250 4 Powerglide
SD 1962 327 350 4 glide, s hi perf.
SG 1963 327 300 4 glide, h/p, a/c
SK 1964 327 250 4 Powerglide, a/c
SL 1964 327 300 4 glide, a/c, hi perf.
SR 1964 327 250 Powerglide
SS 1964 327 300 4 Pwrglide, hi perf.

On one of the decode web sites I was on it said 62-63-64 there were S only suffix all were 327 powerglide. Not 62 only. So where else on engine would there be codes?

427390HP

I have seen that website and I do not use that one because I think it is not correct. That's why I cross reference multiple web sites to provide accurate information.

There is only ONE place for the engine code - on the pad.

What is the casting date on your block? With the block #, casting date, and pad code you will know for sure the YEAR and APPLICATION an engine is from.

This is casting date right. 64-65[/QUOTE]

No, that is the casting number. Casting date is in the same area of the block, on the passenger side. Much smaller font size. Like E284 or similar.
