Jesus, mother of God, that's a long pickup tube!

Lots of the old stuff was front sump, with a short pick up. Which can still snap off with rpm if not braced.
The rear sump have a bracket that goes to a main stud

 

[CompNut]

Fucking Ford with their stupid ass front sumps.

 

[Briansshop]

Nothing in the way of the pan on the 2 I'm building now,so I found some flat bottom box pans. Round track stuff but will work good for me. 10 quarts.



Milodon makes one also,but the availability is on/off.

Today's news.

Comp cams instructions:

Use comp lubricant on the lobes and distributor gear (Part number 103). Cost the cam bearing journals with conventional 30 or 40wt oil

 

[89 Fox 427]

Lifters:

Clean lifters thoroughly with mineral spirits. It is not necessary to pre pump Hydraulic lifters full of engine oil prior to installation and valve adjustment. It is actually undesirable to do so as the pumped up lifters will cause valves to I open during the adjustment process rather than positioning the plunger in its operating position as it is supposed to do. Pre soaking in a bath of engine oil is a good idea but not mandatory.

.0015 to .002 lifter bore clearance is MINIMUM.

I can tell you right now, I'm pretty positive I only have .001" lifter bore clearance

 

[89 Fox 427]

These instructions also state ptv clearance minimum .100 intake, .125 exhaust

Nice. My 1st 351c fox body pan was a kevco. He actually sent me scrapers in the mail for free that I welded in myself (they were causing some fitment issues).
Stef's has some nice pans as well.

 

[BOSS#1540]

Good to know. I ran 60 on both, lol.
I'd stay at the 80 on the exhaust to be safe but intake can be less

How are you measuring this clearance?
9.9/10 you'll have too much lifter clearance even with an aftermarket block

I have other paperwork here that says .080 intake .100 exhaust. I think it was the heads. I'll have to check later.

Dial bore gauge and calipers. Again, I'll have to check later to verify

 

[BOSS#1540]

Calipers? Dial Calipers? If so they aren't accurate enough.
Get yourself a set of mitutoyo micrometers. Snug them up tight when measuring and check the lifter in a few places for roundness.
1.5 -2 thou is all you need. Too much lifter clearance causes an "oil leak"

Jesus, mother of God, that's a long pickup tube!

Just a bit longer than a LS pickup tube.

 

[BOSS#1540]

Could they not put the filter further away, like in the glove box, beside their purse.

 

[Steve439]

I just knew those LS designers were retarded.

Comp cams instructions:

Didn't somebody - maybe the lifter manufacturer - say not to put anything at all on the lobes?

Also comps directions lol

 

[89 Fox 427]

Well. It's been 3 hours of fucking myself.

The gears do not align. I'm starting to wonder if dart quality control is garbage, as I spoke to a well known guy last week and he mentioned such things including blocks not being machined square among other things.
