470 going to the dyno - HP/TQ estimates

When I win the lottery one day I'd build a 4.500 bore, 3.915 stroke 500 cube with B1 stuff & call it good

If you go with the 92% stroke to bore ratio which is supposedly be best compromise for stroke and friction that gives you a 4.15 crank for a 528 revver :)
