to make it fit you have to grind the right hand side of the swing arm about 3/4 of an inch to make room for the engine, you have to make a new lower mount and upper mount. i think it took me about 3 hours to make all of the brackets. i still have to remake the lower brackets just to make them look pretty. if i can i will take pics of it in the next couple of days after i get my engine back together. getting it in the frame is one thing making it run is another. if you are actually gonna do it let me know and i can give you some more help.
I'm kinda sorta toying with this idea as well. Can't find jack for 660's anymore and I don't want to sell it and start all over with a 700. If you made a write up on the conversion it wouldn't hurt my feelings one bit, lol. Not necessarily a detailed step by step spelled out in excruciating detail write up but more like tips and tricks along the way.
Thought about the head/jug swap you did but then it's probably easier to swap the whole thing out.
phucker, thanks for the info. i am really debating whether or not putting a 700 motor in my frame but having to modify the swingarm is kind of a turn off for me. would you be able to maybe take a picture of the swingarm modification?
when you put the 700 engine in, did you adapt the wiring, or did you use the whole 700 wiring harness and now yours is fully fuel injected, if so then you have a complete 700 engine and wiring from headlight to tailight from thumb feed to kill switch, is this right, the grinding mod is nothing, imore concerned with the wiring setup, also does it now have a 700 gas tank. thanks.
700 run/kill switch
all 700 sensors
mid 90s ford f150 frame mounted fuel pump
660 gas tank
custom barker exhaust- barker 660 duals would work just fine on it
custom head stay mount and lower mounts.
modified 660 swinger, i will measure a 700 swinger later today and see if it would work instead.
making the 660 swinger work was easy, just made the area where the engine goes inside of the swinger wider.
