Reply With QuoteFirst let me correct myself on the different sized oil passages between blocks. I was confusing that statement with FE's. No harm there. Thanks for the friendly correction.
The reason for drilling the passage between the filter and the pump is that when you blend the passage into the filter pad you have a larger entry and the restriction for the change in direction is much less. I drill it to 9/16 thru, and then 5/8 for about the last inch, and blend that into the filter pad. It's the first shot out of the oil pump, and I also match the hole from the pump to the block. IMO, anytime you can lessen restriction anywhere in the oil system, especially right out of the pump, the better. Even more so for a system that's not 100% as the 385.
058...you're right. The stock oil system is good for about 7000. As long as ytou're not making more than about 700 hp. The 385 is the same as a cleveland, and the same mods that work with a cleveland, work with it. Maybe you guys are smarter than Jack Roush, but he pioneered the oil restrictors for his cleveland motors a long time ago. What we used to do for them, and I've done on one 429, is take oil right off the main oil galley and run a manifold inside the lifter galley and directly oil the mains. There's a number of ways to do it...none of which are too complicated. I'm not sure, however, that you have a lot of control over lifter bore fit unless you're going to bush the bores, or? The theory is correct, but how do you apply? Buy a thousand lifters and hope you find 8 that are a few tenths or a thou big?
LO...if you're loosing cam bearings, it's because of something else, but I'll let you figure that out. Oil restrictors have been used in 429/460's for a long time. I've never lost a cam brg. I've also run them with no restrictors with no problems. Go figure!
...oh, and by thew way, you aren't going to put any more pressure on the filter by enlarging the passage between it and the pump. "Pressure is equal and even in all directions", (it's a physics thing) and the only way to raise the pressure anywhere in the system is to raise the pressure in the pump.
Man, I stopped participating on this thread because new information was coming up that was not accurate, but enough is enough! This thread with great information is becoming tainted.
yeah, you mean like putting four bolt caps on a two bolt block, and boring a 385 .160" over? I totally agree.
I didn't mean to chase you off your thread, here, LO. I thought it was for open discussion, but you seem to have a different idea. So, what...your info was the great info? All bow to lakes ohhh. You might not believe this, but you aren't the only one here who knows a little about Fords. You seem to have a lot of text available...specs and casting no's and info like that. That's cool. It answers a lot of questions. But you need to chill when it comes to YOUR opinion, and calling someone elses' stupid. You've posted some pretty "interesting" things here yourself. It's not impressive, and you're no John Caase, IMO.
058...it's oil galley, not gallery.Since you are bent on correcting me and others because you cannot admit you are wrong here goes: A galley is a place on a ship where food is prepared, a gallery is a passageway....Look it up. My definition is from the Office Edition of Webster's New Riverside Dictionary. Second: What does horsepower have to do with oiling? Either it oils or it doesn't, so according to you if my engine makes 701 hp the oiling system is inadaquate? In your infinite wisdom what would you do to improve this totally inadaquate system? Third: the restrictors you so lovingly refer to are the restrictors threaded into the driver side lifter bank passage [gallery] of the 351 C as it comes off the #5 main bearing saddle. This is the only basic difference of the system between the 351C and the 460. Fourth: If you really knew the architecture of the 460 you would know ANY block can be 4 bolted regardless of block type, cast web or machined web block. I have done both. fifth: It does very little to drill the pump passage to filter pad to 5/8" as it will not flow much more oil than the 1/2" passage that ALL 460s are from the factory since the oil pump passage [gallery] is only about 1/2". There is only one thing worse than no information and that is bad information. I'm very happy to set you straight as I'm sure you will be able to use this new found info. in your engine building career.
