HOWARDS are machine by Callies i used alot of scats . some cats .some RPMs .some Elings.PBMs. Ohio.eagle and alot of no names the top of the list is Callies Comp star .Scat .PBM for the china 4340 cranks. and there is a top line usa steel? cranks your looking at $1500. and up .the list is long and have used alot of them as well. on the cast steel the scat or PBM is what i have used . for them cracking cast or steel well over power any crank and then not tune the engine right . not use the right damper on it .well its going to crack . i have seen many $2000. cranks with cracks in them it happens. you get what you pay for some of the cheap cranks need to be re ground out of the box .for rods i used every ones. H beams. i stay away from a no name rod bolt . i use the scat has they are weight matched better them some .it can get very hard to take more then 3 grams off a H beam big end and scats are better then that. there is also were they put the counter weigths on the crank they may not be in the right spot and then your looking at much work to get them in to balance . has for them china 4340 i seen one hold up in a 8500+ big chief 565 with alot of NOs still holding
