Wuld it be worth while to upgrade the oiling system when installign a cam that's within the stock Rpm range such as the Crane Powermax 227?


My car has close to 90K on the motor... oil pressure is 40-50 at startup.... and cruising... lowest 25-20psi during driving. The cars my only driver and I need the transpo. but I've recently come upon the time to do the swap... should take 2 days... maybe 3-4 if the valve springs want to be a P.I.T.A., but what do you guys suggest?

The 227 is a 6 grand cam. Peak HP/TQ will probably stay in the mid to high 5 grand range. So essentiallly you won't be spinning much more than stock. You will just be getting more mid range and upper power while maintaining low end.

Whether you have a new cam or not, oil pressure is key to your engine's survival. I would make sure that your getting the right pressures first. I don't know what you mean by "upgrading" the oil system. The stock system will work fine, especially for a small cam if your system is up to par.

Too bad that the damn steering wheel blocks your view of the idiot gauge, but you really need to take a cockpit sweep of the instument panel often to ensure everything is jake: a sudden drop in pressure can hearld a melt down before you can say of f....! JMHO

My pressure is solid... seemed to get better after the new lifters.... but I was thinking about installign the HV pump and appropriate goodies...oil pan and all... on a new oiling system. With this cam... just incase. I'm accumulating parts for a more aggressive motor... but in the mean time...I need something to keep the Snakes away... if you know what I mean.

I would say it would be safe if your oil pressure was around 70psi at startup and 60 psi after warming up while cruising. 40psi while idling after warm. However, the general rule is to have 10psi for every 1000rpm.

Well if you want to, go ahead. Won't hurt anything, but...installing a cam and upgrading the valve train with RRs, sufficient spring pressures, correct adjustments and tuning should be your foremost concerns (if your oil system is good to go).

Since those things are so important to do correctly, I'd put off fooling with the oil system until I was satisfied that everything else was A OK.jmho

Are you pull the motor?

Running a HV pump on a stock pan can drain the pain before more oil can return. Also, a HV pump can put a lot of oil in the heads even with a 7qt pan creating oil problems.

If you can't get by without some kind of oil pump change, just swap the spring in the pump to run a little more pressure, but you will be fine with the stock stuff. I turn mine to 6k every time and have never had a problem for 37k miles.
