[AT] DLTX Question

[Dave Ernst]

Here's some interesting info I found after the last post.
A google search found this site which identifies DLTX usages.
http://www.bright.net/~suiterwo/carbpage.htm
 Interestingly enough the DLTX 71 was used on the 1949 models "AR-AO" and 
the 1947 &48 model year "A", and indeed the DLTX 67 is correct for my "B".

Next, I went here:
http://www.antiquetractors.com/Research/enginehpchart.htm

which shows both the "A" and "AR-AO" both having the same bore and stroke-5 
1/2 X 6 3/4, yet the "B" is 4 11/16 X 5 1/2.
Beginning to sound like jets to me.
Thanks again,
Dave
