Only an opinion, but if the numbers are wrong, it may be a Corvette motor, but it is wrong for your car. My opinion would have me buying a correctly dated Flint block and go from there. Even if it is a Corvette block, but wrongly dated, it is incorrect for you car. If it is a non-Corvette block, it would be correctly dated, but still not original to the car like the other block is. I would go with Flint block, correctly dated.

Thank you everyone for the replies. They have really helped me understand this stuff.

Just in case anyone is interested, I found a '65 Flint block ending in HT (Corvette 350 h.p.) with a D265 date code. Has a VIN on it also.

And that's the thing that kind of bothered me about the C235 date code block I missed out on. The pad had been erased (I assume through decking) so while it had an appropriate casting number, and the correct date code, and was probably a Flint block (never saw it and didn't know enough at the time to ask about the plug) - it may not have been a corvette block originally.

In the end though, I kind of lean towards Dave's opinion. If it has been decked so no VIN or application exists but has a correct date code, a correct casting number, and is a Flint it may not be better but is certainly no worse than a Corvette engine built a month after my car was assembled. I guess it comes down to personal opinion.

That port was originally used to feed the OPTIONAL oil filter on the '55 V-8 engine. One year only for cars. Trucks may have used it for something else. Don't know.

Well the March 23rd block sold before I could buy it, the March 15th block turned out to be July ("G" instead of "C") but now I have found a April 5th casting date. Is that too close to an April 14th or 15th build date?

Dont waste your hard earned money............build what you want, incorrect is incorrect & it will never be original again. Close count or add any money value to your car.........

Build it, drive it.......&........EDNJOY IT !!!

It's kind of close, especially since you already have sample dates from a car probably built one day before yours. As you've seen there are plenty of correct blocks out there, keep looking if you want it to appear original. M2C

If it's a Flint block, an April 5th casting date vs. an April 15th car build date isn't out of the ordinary at all; what's stamped on the front pad?

This thread is a good example of people with incredible knowledge helping out those who can use their knowledge, and the knowledgeable guys aren't getting testy about all the questions. I am learning a lot and the issue doesn't even concern me (don't have a vette yet!) Thats why these forums can be such good resources. Keep up the good work.
John

Thank you for the reply JohnZ. I have been asking for this information but so far no luck. May need to just keep looking.
