Just a bit of info to help you along in your search, The D engine has a 5.5 stroke crank, a 10.75 " centerline rod length and a 16" deck height block. A little math shows the piston compression height will need to be 2.5" for a 16" deck height. thats just the math.
You should be fine if you can find a piston with that compression height. IIRC there are M pistons with a tall compression height, maybe even more than 2.5.
OH, the D series use a 1.233 wrist pin that clamps in the rod with a clamp bolt so your piston choice would be to a piston that can be adapted to that pin size as the rod end would have to be reworked to a different pin size and pin securiing method.

I have successfully put a clamp bolt in the rod, tightened it enough to not close the bore and welded the split and bolt to one piece then had the rod small end machined for a 1.250 pin, slip fit no bushing and it was fine for years so there are possibilities if you are not afraid to think "outside the box.

Good luck, There's lots of power in that engine and not to hard to get out, the engine will also respond nicely to more valve lift and a good cam is some of the cheapest power you can get.
