Mopar 400 block 8 sleeves
Did some miles and give it more and more each time. Seems to run very well.
The only thing that bothers me is oil pressure. It is 25+ in park at 1000rpm and 20 at 850rpm in 1st gear. I did some research prior to installing HS rockers and saw many people complaining about oil pressure with these rockers and also external oiling heads are not helping... thing is that oil pressure is low but not too low. Also Harland Sharp suggests restricting oil to the heads on their website.
The amount of oil going thru the heads now is impressive, when I take the breather off the valve cover on running engine I can see the oil flowing in big amounts, I never experienced that with standard oiling heads, also lots of oil flows from between rockers.
I already modified the connectors that bolt into heads to accept Holley jets so I can restrict oil like that, but what size do I start with? Should I do it or keep it as is?
I see 70 psi of oil pressure over 3500rpm when cruising.
