Hi rebuilding my 77 xs360 engine and was wondering a crazy question. I am rebuilding the pots and was wondering instead of using the OS pistons available, (I am struggling to find and OS kit or all the components independently) (yes looked on Csmnl, ebay etc) can the 360 bore of 66mm be taken out to 69mm and i use a set of xs400 rings an pistons? I am assuming they use the same conrod and I would use a 400 head gasket ? piston length is the same 52.4
I am also assuming carb jetting would have to change as well. but both run Mikuni bs34s
