looking from the front...

Here is a top view of just the flat plate.

VERRRY NICE! And seeing it in a GOLD hue!...Kenny,you know where this is going! Please try to make this a "reality" before April..when I plan to start putting the ole' 440 back together! BTW...do I get a "Decal Buyer's Discount" on this newfangled valley plate???? I hope so! Keep up the good work,my man!

Haha! Thanks eh! I will try to get to the shop tomorrow to nail down some dimensions.

I think April should be a fairly easy target. I would like to have the first run done soon. What would be ideal for yours Randy, would be to ship it with your decals. As for a discount, we will work something out!

Kenny,shipping EVERYTHING at once would be ideal! Know ANYONE who needs a USED Indy plate?..excellent shape,fair price! Waiting for the K-1's to arrive this week..then off to get the rotating assembly balanced. Always a GOOD thing to not only go faster...but improve,and STRENGTHEN the bottom-end as well!

I trimmed the tin even with the bottom of the port runners and bent the "tabs" under each head and sealed it.

I thought about adding a lip that went under the the heads. This would help with sealing. However, this would require the heads to be lifted whenever the valley plate is to be removed. I could maybe make 45 degree angles that bolt to the flat plate. Then the plate could be removable still. This would of course bring the price up, but possibly a better product in the sealing department.

One other thought, would anyone possibly want a screw in breather on the plate? This could be an added option. This would allow you to run valve covers with out breathers to make for a cleaner look. If the breather on the valley plate was in the back, you wouldn't really see it even.

Any other options anyone can think of? I am all ears!

-Kenny

Kenny..I believe a 45* bevel on the plate-to-head buttment,similar to the Indy design, would be the easiest..and most efficient design for leak-proof sealing! The smaller the gap,the less sealent used= NO OIL LEAKS,OR SEEPING! I would keep it SIMPLE..ONE PIECE..more affordable! As far as the breather incorporated on the plate itself...EXCELLENT IDEA...as long as it's as efficient as valve cover breathers! Real glad you're working on this MUCH-NEEDED piece!

Wouldn't it be difficult to baffle a breather mounted directly in the valley? I would think there is less oil splash/vapor under the valve covers than compared to under the valley plate.

I think the right breather would do just fine in the valley pan. This could be an option that is an add in if it isn't wanted.

-Kenny

I guess what style valve covers you have would determine the "need" for the valley plate breather. It would be nice to have that option!

any more on it yet? price? availibility?

i know a couple guys that tried running a vac pump from their valley plate with god aweful results
