after arp rod bolts install less than .002 clearance.

... when installing ARPs you mean?

Not just with arp's. Anytime the crank is polished and within spec, it is fine to use(given, no gouges, cracks, etc)

Oh yes, of course. I misunderstood. I thought you meant if you had the crank polished you could get away with just swapping in the ARP mains without needing an align hone.

Im on track now.

Your crank must be machined after an ARP bolt install, this goes for the crank journals and rod journals.

Do NOT run the car or even assemble the motor until you've had it machined or you're not going to have a motor that runs very well and if it doen the tight tolerances are going to cause some failures almost right away!

you are correct about machining the crank, but the most importing thing to do is getting the rods resized. when i had my ARP rob bolts installed the machine shop had to resize the rods because the cap will not line up right

Are we all talking stock rods with arps installed? Because eagles and scats come wtih arp
s so why would you have to resize them?

I would assume so since he was talking about installing arp rod bolts. If it were eagle, etc, there would be no need to install arp bolts unless the old ones were stretched or broken.

Yeah i was talking about having to resize them when you have stock rods. otherwise if you buy new scat rods or eagle rods there is no need
