All Small Six Any difference in stroke between a '65 and '70 200 block?

I'm scrapping a '65 200 block, single bell housing pattern. Is there any difference in stroke from '65-'70? Half the pistons are seized, already saved the cam and lifters, just wondering if the crank might be worth keeping. I had the head reworked and installed on the 170 I'm running now.

I picked up a '70 200 that is a better swap than the locked up '65.

The 200 stroke did not change as far as I know you can see here:

Probably a 200 crank spare is good to have since you will be running a 200. I suppose it could be used in a 170 for a stroker? If that were true some one with the original 170 block in a Mustang or something might buy it to give their 170 a few more cubes.

Save the rods if you can. They are forged.

Should be able to save the rods, probably gonna push the pistons out the bottom.

I couldn't find any info on if the stroke changed over the years online.

The stroke for the 200 is the same from 1964 to 1983; 3.126".
The deck height is the same throughout its' life at 7.808".

Thanks for the info!
