Are there any other .40 or .45 engines that have the same bolt hole pattern as the YS .45? I'm looking to change from the YS .45 (with a muffler) to another engine, and am hoping for just a drop in change.
Thanks,

Not that I am aware of... 
I have had a YS in my line-up for many years and always had to re-drill the mounts... Keep in mind if you runa macs 7.5cc pipe you will see a HUGE performance increase!
