Rover 4.6 Conrod Bolts?

Hi

I'm after some ARP type bolts for my 4.6 conrods that torque to a specific lb/ft and are not a stretch type bolt. I know ARP do one for the the older 3.5/3.9 engine but doesn't show as having one for the 4.0/4.6 engine.

Anyone any ideas?

Thanks.

When I re-built my 4.6 I was told by my engine machiner if you use ARP bolts that i'd need to re machine the big ends to ensure they are round.

Are the Rover V8 conrod bolts torque to yield or torque to angle?
If torque to angle there's no reason not to re-use them as long as they are in good condition.

Torque to angle. (15lb/ft then 80 degrees) As I'm planning to do the bearing shell renew in situ I was hoping to avoid having to use the torque angle device underneath the car on my back.......

Torque to angle is also torque to yield they should not be reused, never seen the rods but machinists always say they need resizing if you change bolts at all, we always swapped in new standard bolts when we ran Rover rods and never resized and never a problem. We didn't go to ARP because we got a set of Crower rods and then a set of Carillo's for the right money.

ARP do not supply rod end bolts for a 4.6.

In the end I was forced to use STD Rover bolts supplied by Realsteel.
