I posted this under technical too - I hope that's okay! I know I tend to not read the tech board that much.

Anyway here is the deal.

okay so everything is almost good to go but the oil pan. Some horrible noise coming from there, squealing is what I would call it. My husband thought he had a solution but it didn't work. Talk about frustrating!

So with a 383 stroker motor which oil pan do I use to clear the box (now i forget if he said steering, gear of some other box)? Its an 86 block 1 piece oil pan gasket if that helps.

Someone posted a few years back here that they used a Moroso 7 qt but didn't say which one and the link is dead. the pictures on the Moroso site aren't yielding a lot of insight if it will clear or not.

Thanks!
 
I haven't been following your build......don't know what your transmission is, but a bad throwout bearing will put out a god awful squeal when bad.
 
I've got a Moroso 7 qt. pan on my 383 with a 700R-4. I'll look for the reciept tonight to see what part #. I think I bought it from Summit Racing.
 
Just curiious.......did you find out what was causing the squealing noise?
 
You have to be careful and make sure the pan is notched for clearance with a stroker. If not, your connecting rods might hit as the crank spins. The Moroso I bought emphasized that it was notched for a stroker. I had to work late and didn't get home till 9:00 last night and didn't have a chance to look at my reciepts. Sorry! I will look tonight for sure.

I looked on the Summit websight and the pan is # 20195. If you look at the large picture, you can see the clearance notches for the stroker.
 
working on it right now. Might be flywheel hitting the alternator?
 
If the flywheel is hitting the alternator, to use the vernacular...you in some deep shit, girl.
:)

As for the oil pan issue, if the car in question is the 82 listed in your "my Corvette" information, there is no interferrance problem with the oil pan and steering box on that car.

The pan you need for the 86 block should be the same unit which came off your original engine...along with the windage tray and the oil pump pickup.

Typically, a 383 is a stock 350 block with a stock 400 small-block crankshaft or an aftermarket preproduction of a 400 crank. There should not be a need for modifying the oil pan unless the connecting rods and/or their bolts are something very unusual.

If there is a squealing coming from the engine, my guess is it's not a problem with the oil pan but some other situation. If there was a rod clearance problem and you ran the engine, you'd hear a loud banging rattle as the rod bolts "machined" the pan for clearance. You'd not hear a squeal.

In any event, I'll be interested to hear the bottom line on this.

To make a squeal, you've have to have two parts, one rotating and the other stationary, in continuous contact. For example: flex plate rubbing on something.
 
This is the girl version of what it was.

There was in fact an issue with the pan only about 1/16 of an inch if that. I am glad I got the new oil pan as the plug is on the side of it which should help as you know how low these cars are.

But with the oil pan off there was still the squel. I could feel my spirits sink. It was hard to believe yet another crazy problem. So it was the mini torque starter hitting the flywheel ( I was tired I know where the alternator is LOL). So the starter had to come off and he fabricated two rings out of a metal clothes hanger to fit inside and that seems to have fixed it.

They don't call him MacGyver for nothing!

Thank you all for your ideas and just being here throughout this build. I keep thinking its been 2 years since I last drove her. He put the new motor together around this time last year and really just started the whole thing after January so I guess I need to learn some patience. Plus the interior is just about done too. So next year the only thing to do is some paint or some decals to cover the doors.
