+++ What Doc said, we did that years ago,the old 327 block and 283 crank(small journal) trick.Get some 11-1 or 12-1 302 pistons and 5.7 rods,a little methanol and 8000 rpm's here we come! Not a great deal of torque but the sound of that small block screaming like a banshee down the back chute at Williams Grove Speedway would make the short hairs stand up! At the time it was considered the poor mans stroker.Good luck!
