Yeah, I feel the same way as you. I'm sure all is fine with your motor, I seriously doubt Futral would send something questionable out the door

 

i didn't do anything special. just slaped them in and ran it.

i dont think they are even needed unless you are reving it up high, like over 6200 or so. the high hp doesn't hurt rod bolts but the high rpm's do.

i reved that 6.0 to 6800 many times before i got the turbo. after the turbo i shifted much sooner.

 

I was wondering what you did with that old 6.0. Im gonna try a 226/226 so I may want to rev it to 6500 or so. I just hope what I did doesnt decrease the life of my motor significantly.

 

i'm using the pro series in 2 motors with no problems. one engine i did check the rod sizes and they never changed, the other engine i just bolted them in. with the cracked cap design i don't see where resizing would be needed. the bolts do not locate the cap like a conventional sbc.

 

What happend to the 6.0? I mean what failed?

 

i put that motor thru hell. i finialy took it out with a sticking open nitrous noid. . it was a sad way to take out a motor that had put up with so much.

 

I think the cracked rods are all the difference as there is no way to resize them like a regular sbc rod. This past friday I stopped by Futral and picked up some 'pros' that I will be putting in when I drop the pan to fix my oilpump o-ring some time this week. The ARP Pro LS1 rod bolts are all they stock and are the only ones Allen uses. When I talked with him briefly about doing them, he made no mention of any resizing as he has made numerous 'in car' rod bolt swaps.

 

i dont know about the "cracked cap" rods, but w/ the older style stuff you have to resize the rods when installing new bolts. for 2 reasons...the cap will be located a little differently due to the new bolt, and the ARP bolts clamp so much better that it will slightly distort the bore. this may be different for the cracked cap rods, i dont know for sure.

i do know that you can resize some "cracked cap" rods, you have to use an oversize rod bearing since you cant cut the mating surfaces. now whether or not there is an oversize rod bearing offered for an LS1 type engine, i dont know.

the shop i work at all we get to work on from these engines is cylinder heads, and not many of them. i know this info doesnt help much, but there it is, lol. CHIP
