400 stroker or 440

You should build a 400 short deck motor. The first year out is the best because of the filled in webbing in the bottom end at the caps. Smaller mains has less bearing speed and use the B/B Chevrolet (sorry didn't mean to swear) con rod for less bearing speed, weight savings and smaller piston pin. The piston will save a ton of weight. That's the combo that powered the Wayne County Pro Stock to back to back Pro Stock titles 1990-91. It's just a better deal, but 440 is cheap and they based the Hemi on it! It comes down to money.
