What kind of effort and cost would one have to put into a 1275 to get 1400cc out of it?
From basically scratch, unless something can be pillaged from my 998 (highly unlikely)
You can just bore it to 1400 (74mm) but really, you are just giving block life away. I'd stick with 1330 or 1360.
$150 for a good bore and hone job, and ~$300 for pistons.
$140 for a crank regrind (or $240 if you want a big journal one stroked too). Add another $200 or so for 4x S rods if you stroke it.
$100 max for bearings and thrusts.
$60 for an oil pump.
$130 or so for a cam grind.
$100 for cam followers.
As for the head, it depends. New valves and springs and guides will cost about $250. Add head reco work, and porting if required.
I'd also need 7.5" discs for the front..
I think
