I know you are trying to help. It's hard to show feelings with a key board. I appreciate all of the replies so far, really!
I did not check bore size because of the reason you mentioned. 65 psi was cold idle. At 2200 rpm it was at 75 rpm. I didn't take it up higher than 3500 and it remained at 75. When I raced it with the engine at temp. my oil pressure sets, or sat at, 75-80 psi at 6500 rpm.
With that, what mod would you recommend? I'm leaning toward the one that blocks the oil from #4 to the cam bearing and drill and tap in a restrictor into the main oil galleies for rocker lubrication. If any mods, to me, this one as described in the "Power Adder" section, would work best on a street/strip engine like mine.

i wouldn't block any oil to the top end. the pressures you listed above are fine. we run similar pressures on engines that regularly see 7000+ rpm at the track and get driven hard on the street. it's all about volume, not pressure. open up those main passages so the volume gets to the bearings. you'll be surprised how small some of them are as cast. having the 1/2" pickup is great, but by itself it doesn't help much. you need the other passages opened up for it to be effective. one other thing, replace the rod that spun the bearing, don't repair it. if the one next to it got hot, make sure it's checked out preperly or replace it too. hopefully the rest of the damage isn't too bad.

There are different reasons for restricting oil to the top end. The cam itself is a "Pulse oil restrictor" to the top end.

In a race engine, a additional restrictor will also help to prevent to much oil from pumping to the top end at high RPM draining a insufficient pan.

Some will groove the cam journal for a constant oil supply to the top end vs a Pulse cam supply. That would need a restrictor to the top end.

The Mod in the Power Adders section has a restriction too. As does All the above situations.

But, The Power Adders Mod addresses the #4 main Oil supply drain of the valvetrain that Robs the oil supply to #6 and #7 rod journals that get the First hit of a weak oil supply.

All the other mods wont! They will still pull/rob oil from the #6 and #7 rod bearings to feed the upper valvetrain.


At minimum while your block is apart drill the angled oil galley feeds from the mains to the oil galley to make sure they are clear "all the way through".

The "Power Adders Mod" is alittle extreme for your ride IMO. But, I would still consider a Jet restriction in the block or head for your ride. Lighten up on the STP too a little.

Your car is Mostly a street car. But with the 11.sec. trips down the 1/4 it still thinks its a race car. If and when any bearings run out of oil @ 6000 RPM, Does it care??
