Just talked with Barry at ARE and he told me I needed new main bolts since they were tty. I didnt think that they were..just the head and crank bolt/s. Can anyone confirm this? I only rev to the stock 6200 limit so if the bolts do need replacing, do i need ARP studs?

 

They may be right or not. Just because you use the torque setting followed by an angular setting does not mean you have a torque to yield fastener, merely that you are achieving a specific clamp load. LS1 tech manuals mention tty for the head bolts but there is no mention of tty for the main cap bolts. Mike.

 

I asked Chris at Katech about that when I dropped off my block for the machine work

They are NOT TTY

 

so i can reuse the main bolts in my super hi revving 6200 rpm beast <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

The main bolts are reuseable, but you may want to consider some better rod bolts. I didn't feel too good about the stock rod bolts after I felt them stretching, so I used Katech's rod bolts in mine.

 

Yes they are reuseable but its not too much for some replacement stock ones.

I have ARP rod bolts...just wondering about the mains

 

Put it this way. I will re-use my bolts as I've seen nothing to say otherwise. If yours look good you could think about doing the same. They aren't tty. Mike.
