stroker life span?

Forced induction will last longer than the side load stresses caused by a short stroker piston with more rod angle. FI uses original engineered mechanical movements. Build a strong bottom end and you should be good to go if you can keep the pistons rich. you can build a 451 with 383 or 440 rods, and a tall and short piston . short rod has more side load, but the short piston has more rock potential.
