Cb750 motor replacement

Devintb19
Hey fellow Cb fans i need some help im building my dads old 74 cb750 and had the motor stolen. I have a friend offering me a cb 550 motor and have considered using it but wanted to see if anyone knows if this thing will even fit my frame? minor fab work is nothing to steer me away but I dont really want to spend a ton of time changing the frame just to fit this motor any help would be awesome.

I am about 99% sure that the 550 is different. I know that aftermarket frame manufactures have a different frame for the 550.
If I were you I would watch craigslist for a good 750 that does not have a title. Here in Kansas City they come up quite often.
