360 con. rod bolt sizes

Mopar 360 rods are plenty strong with just arp 3/8's bolts, they can take 450hp with just good bolts, I would not go to bigger size bolts in your stock rods drilling it out would weeken it. if your going over the 450HP mark, just get some good aftermarket rods

E340,

450hp would seem a little un-realistic for me since I am going to have to keep the head work down to a minimum. Using my current "J" heads with the 1.88" intakes I believe will be my limiting factor (as well as my new compression constraint, thought about the kb190's but it was raising eyebrows at the m. shop) I've never ported a set before either. These will be lucky to even get gasket matched.
Stock rods w/ new ARP bolts will probably be the call.

Thanks
