Rockchip, where are ya?
Anyway, Ross makes a 4.375 bore (400 block) piston in 1.421 compression height to fit .990 pins. There are lots of low priced H beam rods made with 2.200 rod bearings, and 6.8 long. Put the whole deal together with the 383 crank ground to about 3.52 stroke, and you have about the cheapest good stroker combo IMHO. Total compression height works out to 9.981, or close to perfect. It gives you an off the shelf rod, piston, and the only extra machine work is offset grinding the rod journals. For those that get their pantys in a bunch over rod ratios (not pointed at any one in particular!) the rod ratio comes out at 1.932, almost ideal.
Another good thing about this combo- price the difference between the 2.200 race rod bearings and the mopar 2.375 bearings. I paid $180 for my last set of race bearings (-.001) for my Mopar sized crank.
