windage tray for mild build ?
I am building a mild street 400 for the street car. The 400 had no windage tray from the factory. Should I look at installing one for a mild 400 build? I am thinking for $100 can't hurt but don't know if it would be a waste of money.

I think I would get a pan that has the sump built in to help contain the oil at the pump.Tom

Not worth the effort or cost. I don't even have one.
|
I would, especially on a street engine.... We always try to use them. The factory spent a lot of dough installing them on millions of engines.... I'm betting they did something positive. Pontiac "did things for a reason". They stopped using windage trays when cost cutting took precedence over quality.

I don’t have one. But, I do run the Canton 15-400 pan that keeps the oil away from the crank. Even at 7 qts.

You need to check caps if they are even tapped for one
|
What year did they stop using them?

I believe the factory stopped using them in mid 72 when the baffled oil pan became the standard.
The baffled pan was instagted by the handling that the Trans Ams where capable of. |
The 1974 engines still had the windage trays, they stopped using them in 1975 from what I’ve seen.
Had ‘73 and ‘74 455s both equipped with trays. Also had a ‘75 455, no tray. All three were virgin not rebuilt. All 3 engines had the baffled oil pan. |

https://www.gtoforum.com/threads/pon...e-tech.137776/ Similar information regarding production dates within the H-O Racing Pontiac book where it was stated "Pontiac has used windage trays on all their V-8's up though mid-1973". ( Information provided in this post does not represent any endorsement. And unless specified it is not based on personal experience and is offered for general interest only ) Note the comment and pictures regarding the full length tray was more prone to cracking. That happened to one I installed many years ago. . |
Here is a links on discussions regarding the factory trays cracking. These are only two of many such threads..

I have a 74 YY 455 that doesn’t have a tray and a 73 YC 455 that does.

If your caps are tapped it seems like a no brainer to add one. Windage tray and/or a factory-style baffled pan are a baseline for any build IMO.

My engine was a 74 400 and had no windage tray. Caps are not drilled for one. Lower dipstick tube was bolted to the top of the center cap.
I was thinking of a windage tray that I used on the race car. It mounts between the pan and block. https://www.summitracing.com/parts/c...8/make/pontiac |
Mike, using that tray, how is the pan gasket situated?
