Would prob be on a std bottom end thats been lightened and balanced with ARP rod bolts, low comp and freshly rebuilt.
Your "decent" bottom end is a bit more "Mega" bottom end I think
. I have got a set of Arrow rods but didnt fit them to my latest build as it was never going to really be over 500BHP..
My nova is on arrow rods, and steel crank etc, to me thats just what you do when building a 500bhp high revving engine, although ive not got round to dry sumping it yet, will do once its run in probably though.
If you are on a standard bottom end, then hydraulics are probably fine for your requirements TBH, especially if you are on the standard oil pump which I wouldnt want to trust beyond the 8200 or so hydraulics will cope at.
Std cossie crank is all steel as you prob know, good for 600+ as advised by a few very reputable tuners, and got a 5 bar oil pump. Was just wondering really as If I do go GT30 ext in the future it would make the powerband a bit bigger at the top
I thought the weak link would be the std valves?
