im not sure where you buy a $1500 crank at but that is more than double over retail! unless its a billet crank wich is only around $1200. this guy asked for an opinion and i gave one to him dont bust my ballz because i gave my opinion. he never mentioned that he already had a hot rods crank (stock stroke) he obviously has a few bucks to spend because not everyone has the cash around to build a 4mil cub like he was asking he would still have to buy the 4 mil crank.
so this is my opinion
7mil crank forged
7mil cub cylinders
65 bore
and trench the cases for the stroke.
your opinion
4mil crank forged
4mil cub cyinders
68 bore
i still see him buying new pistons, still has to buy a crank 7 should be the same price as a 4, has to buy the cylinder stock 4 and 7 are all the same price, and trenching is only 150 so i see him spening a whole whopping 150 buck more and and would have in my opinion a better motor.
once again all IMHO
