My friend knows a guy who has an engine he says was out of a 65 Vette. The casting number on the back of the block reads 3892657. The heads read 51239 F0035HE. My info comes up with 65 327-300 heads on a '67 engine...he says the engine was never apart and the heads belong to it.
Can anyone identify this engine?
Thanks
In 65 HE is a 250 HP. HF is 300. In 67 HE was 300 HP was the Flint designation would have been a V. Block is definitely 67. Where is the 51239 located?

Looking at the engine head-on, 51239 F0035 HE reads left to right on the passenger side pad in front of the head.

Either you're mis-reading the F0035HE, or it's a bogus stamping; the two digits after the "F" can't both be zeros. Also, the "51239" is missing two digits - it has to be a 7-digit number. What's the casting date on the rear block flange, about 6" toward the passenger side from the distributor?
The 3892657 block was never used in a '65 Corvette; it was only used in '67 in Corvettes, although it had many usages in passenger cars and trucks from '64-'67.
You're right I could be misreading it, I'll look again. Also should the extra 2 digits be after the 51239?
The first number should be a 5 standing for 65 followed by a 1 which is a filler number starting the production number sequence. The next 5 numbers would be the end of your serial number ( production number like 12345.)
OK...I screwed up, the first group is: 512395 then a space. I cleaned it, soaked it, brushed it, but could not even get a ghost of another letter on the bare metal. The second part is: F0305HE
Does that make anything clearer?
Thanks for your help.

I would say this is a 65 250 hp, manual trans 327 out of Corvette VIN 12395.
Cannot get any other numbers off it...Would you say it is a definite 1965 from what I can give you?
What is the difference between a 250 and a 300 besides the carbs?
Thanks again.

If the engine is stock one easy visible difference is the fuel filter on the 250 HP is internal ( in carb) and on the 300 HP is in in-line between the fuel pump and carb.

[QUOTE=5thvet;1576530078]AFB on the 300 vs WCFB on the 250, different intakes 3844457 for the 250, 3844459-300, 2" exhaust on the 250 vs 2 1/2" on the 300 ( if manual trans).
I thought 1965 250 heads were different from those earlier. What size were the valves pre 65 as opposed to 65s?
