Yep, you need new rod bolts, main bolts, and head bolts everytime you take them apart. Unless you buy non stretch hardware such as arp bolts

Always replace.

If they are OEM bolts then they are 1 time use only, this is why many people go to ARP bolts/studs since they are non stretch and can be reused over and over.

At what power would main bolts become a limiting factor?

Speaking from experience with other cars - a lot of power. My z28 makes 400 horsepower and when I rebuilt the engine back in the fall of 2011 I reused my main bolts - it is fine on that car. However, I did have my rods reconditioned with ARP rod bolts installed.

The only perk to an average car having those main studs is that they can be reused so if you take your engine apart frequently, then they're great to have. If you don't plan on taking the crank out, then stock main bolts will probably be fine.

The engine in a Z28 is a little different. 400 HP from a V6-V8 doesnt put the same stress as a 4Cyl making the same power. But generally main bolts have used in applications up to 500 HP, even with head bolts they can take quite a bit. The main advantages of studs as people have stated is the ability to reuse them, and the basic guarantee you won't lift the head and such.

Right. What I meant was it its all relative, she should he increase his power by 50% or even double it he well probably he fine.

A peace of mind, too, goes a long way.

Are you 06A or 058? I have a set of brand new 06A OEM connecting rod bolts if you need them. I am not even sure the ARP rod bolts will fit into the stock rods. Anybody want to confirm?

Sometimes if the diameter of the rod bolt is larger than stock it will oval out the rod, or give it an egg shape. A machinist can take care of this with a simple recondition.

The machinist can tell you exactly which bolts will fit and which will not.
