Hi all,
The date code on an FE Block is near the oil filter If you  need more details check out the site 428cobrajet.org  It has some good info and pictures to show details.
Hope this helps.
Regards R.R.

Sorry guys I was told by the guy I got it from it was a 67 block

Turns out it's a November 1965 date

That's disappointing to find out,

Sorry

[GT500J]

Any idea what this is worth? Thanks

Probably a $1500 to $2000 item but it is a part for a vehicle with less market potential then a '67 GT500 so any price is speculative at best.

The issue with those blocks in general is that they will take bigger over bores which is a plus but 1) they have a tendency to pin hole at say something like .015 or .020 and generally need to go .030 but 2) they also have a peculiarity in that the engines SEEM to run hotter at larger over bores. "A reputation of running hotter with an overbore".

That can be a very unfair speculation that effects value because that seems to be a random situation but it is what the discussion centers around often.


Having been in search of a "period correct" block for a late '67 GT500, it took me quite a while to find one. About 30 years in fact. Others may comment similarly as well with the determining factor finding a "good period correct date" for your vehicle?

Most of those blocks likely will come from unrestorable Tbirds. The saving grace making them useable being that none of the blocks are chassis number stamped by Ford, so no one can prove it is original to the original Ford build, just that it is period correct, even when IT IS original to the car.


A non rusted or corroded standard bore A scratch with a casting date within the expected Ford variation of car build v. engine build date is gold. That is the king of the hill. Those could reach or may have reached a $5,000 vale already? No one knows for sure, just what we see in asking prices. Potentially as valuable as a 427 side oiler block in similar condition?

It being .030 over now is not great . Most 428 blocks need a sonic to go .040 and that's about the limit of most 428s. It being a early block also makes it one of the least valuable.
