We have built two A14 engines with A15 crank, A14rods and pistons without machining the pistons, instead we have used the A14 "pollution" head with bigger combustion chamber! With this combination the squisharea is almost zero and the compratio is suitable for a mid tune street engine. With a 290degree cam and twin carbs, extractors and electronical ignition this engine have shown good results in the dyno, 128hp! I don´s recomend this for a race engine nor a longmiler but for a cruiser slash weekendracer this is a good setup, these engines has been driven hard without big problems. My friend bent some valves when the throttle jammed at full speed.
