Rods have been known to let go as low as 190bhp but others say they are ok at 270bhp so I think as long as you dont go silly revs as you say they will be fine, Mahles are good for 300bhp+ so there is no worries there.
My pistons should be here end of the week I think!

Always worth asking Newmans, see what they will do! If I had known the off the shelf RST cam was as lazy as it is I would of asked them for sure!!
Yeah the 33 or the 285T are both nice profiles from what i've been told.
