Just in addition to the above, I have an early early yb. I'm also running a dry sump, the remote adaptor I have has mounted where the original oil filter would have mounted but there was no modine in place. Just the stock filter to the block face. In this instance, where can the 15mm outlet go on the rear of the block?! Header tank or t piece into the lower rad pipe or swirl pot after thermostat?!
