out the top. arp rod bolts and oil pump pressure relief valve mod on new engine.
What is the oil pressure relief valve mod please? Just having an engine built for my track car and have arp rod bolts and oil cooler on the way. Will do this too if it's a good idea.
Take it standard engine is more than up to regular track day use? Just want reliability really. Not chasing figures as more than happy with how it goes.........at the moment anyway!
