I am looking for an oil pan for a 400, Summit lists 1 from Spectre that fits 68-77 Firebirds, but a stock pan would be nice, anybody used the Summit chrome pan or 1 of the other chrome pans listed on E-bay that are even cheaper. I have heard that cheap chrome pans leak, any opinions, thanks Jeff

I used a Milidon stock replacement.

It's not the pan than leaks. It's the fact that the replacement oil pans are all machined to use the mid '70's rubber 3-tab rear oil pan seal which is prone to "blowing" out causing a nasty leak. There was an letter to the editor in HPP back a couple of issues on this subject and it happened to me so I need to pull my engine back out down the road.

There are a couple of solutions. One, put gasket seal on both sides of the 3-tab seal, let it dry, tighten down the pan and pray it will not blow out, or have an aftermarket pan modified to accept the much better replacement design 5-tab rear seal.

The HPP article also pointed out that if you have an early block, where the rear bearing cap is machined with a groove to accept the early cork rear pan seal, you are also good to go using that type of seal with an aftermarket pan.

I used a stock steel replacement I got from PAW. Seems to be working fine so far.
