Well, the 261 I thought i bought turned out to be a 235, or so i think. The block number is 3769716, which indicates a 58-62 235, yet on the pad where the captains bars would be for a 261, it has D261 cast into the block. I figured that meant it was a 261. Plus, i compared the rods to a picture i have and they appear to be 261. Is it a 235? Oh, It also has an "848" head that came with it, indicating its a 235. Are these "high" compression heads worth anything? THanks a lot.


1955 Chevrolet 210 2 door Sedan
a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.

That D261 is the date that the block was cast. It reads as:
D= April
26= 26th of month (April in this case)
1= year '61

It's a coincidence that it happens to read "261," and a confusing one!
As far as I know, the rods would look the same, but I'm not sure if they would be longer from 235-261. Hope this helps.

Check out : http://www.inliners.org/becks/BCN2.html

1960 Chev Trk Engine block F0361A block casting number 3769716
1961 Chev Trk Engine block F1204J block casting number 3769716

So, it looks like the block is a 1960 or 1961. With B.J.'s information, this seems to confirm a 1961 block.
