Default anyone here have 1/2" head and main studs?

just wondering what the standard ARP 7/16 studs will take compared to the 1/2 studs. i'm goin for over 1200hp on race fuel with the 6.0l iron block. also how much did this cost you at the machine shop and what machine shop did you use. what equipment should i look for to make sure its done correctly. i'm in NC/SC. thanks.

I would ask around at the big HP guys (1300+ HP) such as W2W and HPE(the only two i know of off hand). If you want a motor built to withstand the HP levels you are talking about then these should be top on your list as they both are well rounded in this territory. HPE is building my 398 6.0 block to withstand 1500 hp. The short block was priced around $4500. Long block(fully ported 6.0 heads with farrea super alloy valves), jesel rockers, and morel lifters puts me at around $7600. The heads were pretty cheap so i would factor in a bit more for those. Also i have a set of 6.0 heads for sale if you're interested.

What does Kurt have on the engine in Casper? That motor made nearly 1600hp right? It was something like a 352ci alluminum block.

We use a 1/2 head stud with a std 11mm main stud. Casper has a arp main stud that is longer to pass thru our girdle system that we use on high hp engines.

We have not tried high hp aluminum blocks yet. The LS2 block has many improvements that will help in the high hp engines. I would use a LS2 block to exceed 1500hp.
