Same here, his 4.250 crank and 6.535 rods. machining is the best. Every rod and main journal measure exactly the same from one side to the other. Makes it easier to get the clearances you need. I found the same 70plus lbft tq to get the stretch recommended using his lube. I used his recommended 30# plus 60*method when I put it together. My Eagle crank that was in the 408 was so over polished that the journals were smaller in the center of every journal.
