Thanks guys but arent those specs for L67?

You need to plastiguage it anyways.

Have you done that yet?

Don't need to, but highly recommended!

Well there ya go.

the whole world uses plastiguage it takes some time to put together and take apart and put back together, but well worth the time, some times the new bearing is fvcked up and no micrometer is going to tell you that.

^^ very true, your car your build, do as you wish, I'd plasti everything.

Blown you should go ahead and order some arp bolts

Replied to your PM.

Connecting Rod Cap Bolt
27 + 50° N-m
20 + 50° lb ft

is what I follow on stock bolts, but like you said I went with ARPs and I followed their specks.

I always use plastiguage, takes but a few minutes to save a wold of headaches.

When I built my engine, I removed the L23 rods bolts, from my brand new rods and installed my ARPs and then took them to the machine shop so they could line hone them straight and true again because the different bolts will change the shape of the rod some because of the different torque.

Stock rods, with the stock bolts, its a good idea to have this dome as well, install the bolts, torque them, and degree them, and have them honed. Though the bolts are TTY and "one time use" You should be fine running them in the engine after this is done. You haven't "used them" for say, but you have to torque them, and stress the cap/bolts to get a true and perfect circle as if it were installed on the crank. From the factory brand new, this is already done to the rods, I would assume...but it never hurts to for sure follow through.

Thanks for stepping in farns.
