Searched the site didn't find an answer ,, Building a 408ls,, What will new GM bolts hold ?? Are they torque to yield ??throw-aways like the head bolts? I bought the ARP studs for the heads, reading about the mains, saying to align bore if you use arp main studs,,WHY NOT WITH NEW gm??

Arp main studs have a higher clamping force which will change your clearances slightly... If you plan to be above 600hp then arp main studs are good insurance, but a lot of builders don't recommend them till 800-900hp...

You will hear mixed reviews on it..

I went GM on my 370 intended for a 300 hit...

With FI I'd go mains no matter... Motor or normal hits GM.
