Intake valley pan

[fleming442]

Is there supposed to be a smaller tray that goes above the camshaft in the lifter valley under the valley pan on a 403?


Something like this

You did get a roller cam!!!!!

I know that splash plate came on earlier engines; don't see why a 403 wouldn't?

No thats just a generic pic

One of the guys said dont forget to install the plate and i ws like WHAT FOOOOOOOOOOOOOOOOOOOOOOOOKING PLATE??!?!?!?!?!?!!?

 

[fleming442]

Should be the same across the board (260-455). You have the (2) 1/4-20 holes there, right?

 

[olds307 and 403]

I have never used that plate.

My 403 has no provisions for that tray to be mounted in it.

Don't worry about the plate. You have no way to attach it anyhow. Ive only ever seen it on blocks that are open in the center of the valley and you can see the camshaft.

 

[fleming442]

Agreed. I don't know about the newer blocks. It looks like casting it in was cheaper than stamping a plate and tapping holes.

So are you going with the turkey tray, or not? I'm leaning towards not, myself.

I dunno



I picked up 2 felpro trays from rockauto in the clearance section for 4 buxx each

They fit nicely and "lock" in.

But I have no idea yet

I have the mondello Windage tray in my SBO and felpro metal intake gaskets sealed with a good amount of RTV on my Edelbrock 7111 intake. The intake runners and coolant seem to seal awesome getting the front and rear to seal and not leak oil different story entirely.

Previously had the windage tray with fel pro fiber gaskets had vacuum leaks I could never find oil leaks and seeping coolant

First set up I had was a factory turkey tray and I believe I was able to seal that one I think

As a disclaimer though I am terrible at dealing gaskets it’s sad to say but I’m not sure I’ve ever had a dry gasket on the first shot one day though maybe
