Hi guys ( and ladies)
. Just looking for some input on a 455 build do I need a valley pan???and how about a stall converter pretty bumpy lumpy grind installed by eng builder comp cams says on their website a2200+ should be used...what if I use the stock torque possible fragmentTion!!. Thanks ...crankit

 

Not sure what you are asking on the valley pan.
Are you referring to the oil baffle that bolts in above the cam tunnel
or the “turkey tray” intake gasket or the aftermarket Mondello type valley pan ?
I would follow comp’s recommendation on the converter.

 

x2 on following the manufacturer recommendation on an aftermarket torque converter. You don't need to install the turkey tray intake manifold gasket, but I wouldn't leave the cam valley cover out of the engine.

 

Hey matt..I think iam going with the after market mondello style valley pan some have said the Turkey tray type dont seal well on alum intakes??? So no getting around the converter issue looks like a stall is the way to go dont want to frag my bell housing ...thank for the reply ...crankit

 

The use of a turkey tray or not, is up to you. The factory used turkey trays on their aluminum intake installations.

 

Thanks don...I have watched a few turkey trays installed and they look like ro many problems compared to aftermarket bolt and forget it with conventional gasket...thanks for the input..crankit

 

I found that composition intake gaskets under an aluminum intake manifold was not a “bolt and forget it” deal. I had to retorque the intake bolts twice at 2-3 month intervals before they stopped getting loose. Apparently the aluminum intake expansion and contraction during heat cycling kept crushing the gasket slightly, which resulted in loose bolts.

 

Hey fun...I see the confusion in my post...I meant the valley pan is set it and forget it now the composite intake gaskets are as you said retorque after a few heat and cool cycles...seem to me the turkey tray is more fiddling than its worth... thanks for the comments...I have alot more questions coming..thanks....crankit

 

If you want a great Stall converter call PTCRACE in Alabama and there is an Olds guys who works there but you really need to know your cam specs otherwise just cherry pick and get a 10 inch 3000 stall loose or tight depending on the weight of the car.

 

I have used the turkey tray factory gasket with aluminum manifolds. As a matter of fact that’s how olds put their engines with aluminum manifolds together.

Having said that, I think the composite gaskets are more forgiving when it comes to machining tolerances. If the block, heads, and intake are machined exactly how they are supposed to be, the turkey tray should work fine. If the block has been decked, heads surfaced, or the intake not machined exactly right, then the thin turkey tray might not seal as well.

Get with a reputable company for a converter recommendation. There are a ton of variables in converter stall speed.
