I have just set the cab on the frame no bolting and it seems real close to the valve cover at the fire wall. Just wondering about any fit problems anyone has had. Thanks

If you use your original clutch housing, flywheel and clutch assembly, the rear of the engine has tyo mount in the same location. Depending on your 261, you might have to adapt the front mount (maybe by using your original front mounting plate - maybe someone who hs done this will post).
The major possible problem is the water pump pulley/shaft protruding too far. Maybe some else will comment on this.
The lengths of the 216/old-235/new-235/261 blocks are the same. If I am wrong, we will hear about it.

The rear of the valve cover (Offy) is close to the firewall be clears it okay. No rubbing. In fact, I lengthened the cowl drain hose and put it behind the rear of the valve cover so it would dump water away from the cover itself. You may be able to see the clearances on some of the pics in my engine rebuild album. I have the single front mount and the two rear mounts on my 261. http://community.webshots.com/user/geezer | | |
