Crankshaft Scraper HP

put a corvette hp pan on my A been running it a long time

used with a baffle best for the $'s spent

think they are a repop item now???

hi$ item on ebay for originals.............pn#359942

 

Wet sump yes, no dry sump experience. Guys with that much ching wont let me play with thier toys...

 

I guess not

 

Yes I have....a 5 inch pan is good
A proper pick- up box is nice
Pass side kick out from the pan rail min 2 inchs full length
We use a rear mount starter when poss so a notch for starter clearace is not needed. But can't always
A built In curved tray with louvers is good but not necessary..... More important to corral the oil and have a proper scavange
There should only be about a qt in the pan when it's running if proper
Remember the 12-14 in of vacuum from the oil pump will keep the oil down

So after all this ramble I'm going to tell you that a trimmed scraper ( within .025 of every contour of the rods and crank full length of the pan rail) is a waste of time in this type of engine

Thanks Tony

 

So here's the next question (related) ... cam/lifters are apparently lubed by "splash oiling" ... if a street engine (plenty of low rpm/idle) is equipped with a windage tray and a crank scraper, is there a chance that the cam/lifters won't get the needed oiling?

 

Not according to Al...

I've seen a BBC dry out and ruin a flat tappet cam, but I'm sure there are a bunch of guys out there that have done it with no problems.

 

Your forgetting that oil is running down the sides of the lifter from the clearance in the lifter bore
We also use Lifters with a bleed hole to pressure oil at the face.... But not always

And I'm assuming if he is using a 5 stage drysump in a BBC
He prob is using a roller ....and those are just fine also with or without pressure pin oiling.... But I do like the idea of extra oiling at the pin... Not because of idling but valvetrain loads at rpm
