I could drive this car like it ought to be drove all day long and there would never be a problem. But when I started the project I was looking to build a cute little bracket car. 1/4 mile will have it see 4K but probably not much more. To be honest 4K sounded like a 'tractor' motor gone wild! Still, I would like to know that everything is OK with it. The book says 5 quarts of oil with a new filter. I am above the full mark but the filter probably doesn't hold a full quart either. I will see if I can get my oil in 20W-40 and then add some and try it. Like I say I'm not like a kid trying to blow things up!! Oh yea, I plead ignorant on the lifters. I bought B-2083s from Hylift Johnson. Did a visual on the height and diameter but didn't know to check any further. Maybe I got that wrong?
No, the advice was wrong.
You don't need to redrill the rocker shaft on and engine that doesn't need lost of oil to the rocker gear.
Period.
Just asking for trouble. Not your fault, the evidence has been around on every engine build, the feedback is that when you do anything at all to increase the stock non adjustable 250 or 200 rocker gear, you cause a potential oil starvation issue down below.
A combination of light oil weight, White Box HT 2083 lifters that you can't be sure arn't defective, and the normal issues which also afflict the similar Ford FE and Cleveland style engines is likely to be your problem.
Go to HT 900 R lifters, and recheck your pushrods an adjusters at full lift. If the ball ends don't wor together, get another kind of pushrod, or have them die ground and linished to clear the rcker arms.
Check with Bob the Builder on what lifters he used in his 62 250 pickup Ranchero.
50 bucks outa do a change for you. I'm baking on lifter collapse.

yellow terra rocker arm install tips, Post #1 by rbohm » Sun Aug 24, 2014 5:09 pm
When you install the yella-terra rocker arms you starve the distributor gear & camshaft gear of very needed lubrication.
To fix that condition the second & third lifters are on either side of the oil hole above the gears.
You can cut a .025" x .025" groove in those two lifters and that will flood the area with the necessary lubrication to prevent scoring of the gears.

Re workig the oil to the top of the engine by restriction is quite okay, its not a 7000 to 9000 rpm 351 C or boss 302 race engine where strangled oil supply to the springs will kill valve springs...its basic prudence the Aussies used all the time.
I'd say there may be a problem with particals in the oil galleries, even for dillengent people who have carefully done the work. I'd add some ATF to your oil, and redo the lifters for 50 dollars. There is a 12o thou height difference between 300/351c lifters, although you can swap them, you just need to know what's the best set for your needs.
HT900R's are what I use.
Before you do, check with Will and Bob.
I'm thinking check the clearances on the oil pump gears need checking if there isn't instant oi pressure. Could be scored to heck.
There are a few issues gaskets being used on pump to block mating...you don't need askets, but you can fit them if you have an oil problem.
1bad6t1 had similar issues with his 170... sometimes Ford does stuff on engines which cause problems when you use White Box lifters.
