I have a manual buddy! Just don't have it in front of me right now, so I figured I would ask you guys on here. I'm just trying to figure out my options. I've read that the stock main bolts are good for around 750 HP. Thats plenty for me. I know I can buy ARP's but if I don't have to I don't want to. My plans are to run this motor until the end of the year, then build a bigger one. So why dump a bunch of money in it if I don't have to.

If I put studs in it, don't I have to get it line honed?

I went through this deciding on parts for my blower motor..All the top shops said ARP main studs were a waste on anything under 800RWHP... Just finished assembling my motor stock main bolts, ARP head studs...

You should in no way ever re-use the inner torque to yield bolts. They are a one time use only. The outer cross bolts are not torque to yield and can be re-used however. Use the part numbers above and get yourself a set.
