Is this the same crank that came out of your engine?? One thing to be carefull of is; don't switch the center main caps. They go on two ways and I've seen them interchanged too.  The rear main seal can be tricky as well. Also; don't tighten the oil pump screw to tight, just "snug" and lock the nut.  Good luck.

According to the Webrodder Stovebolt Stroker series, the 235 pressure oiled and 261 cranks are the same (I don't have my books with me). So why it's marked 261  unless thats part of the casting number?
My, what a steep learning curve. Erik II#5155

There the same, the number (casting) is probably, just a fluke.

It will be just fine. Try to find a 'later' year 261" for your next upgrade. Happy trails.
