crank swap

["Jeffery Maurer" <jlmaurer@msn.com>]

I have a '72 1296 and have just aquired a 1500 crank ground 20 under. Will the
crank fit without any major modifications. I have a set of NOS flat top
pistons,and a pair of weber dcom,similar to dcoe, and a early 1296 cam and
bearings I would like to install also. Will this combination work together?
Will a clutch change be required and if so, will the original '72 transmission
spline to this clutch disc.
         Thank you for any and all input.
