What about the 440Source Billet Steel Caps? Any quality issues with these???




Randy I am using the 440Source billet steel main caps. I also use the ARP main studs. Had all the mains align bored and honed to size. I am making right around 600 hp and so far everything is holding up great. No problems at all with the Source main caps with the ARP studs. I also like to use main studs with anything over 500 hp or any eng that is going to be raced. Ron
