Front or Rear Sump

[Skier0277]

First I want to thank everyone who participates on this forum. All of your posts have been very informative and helpful. I am currently in the process of planning to build a 65 Coupe in the spring. My question is regarding the engine for the car. I am considering using Fords 427 crate Engine with the aluminum block. This engine can come with a rear or front sump. Do anyof you have any experience or suggestions with this engine and which style sump do you recommend? The model numbers to the engine is the M-6007-Z427AFT or RFT. Thanks again for your help.

I have a 302 but from the looks of thing there is a lot of room and do not think it would make any differance. I would think rear so when you accerate the oil is in the rear?

Welcome. I have no firsthand experience with the engine or those oil pans, but I do know that if you plan to take the car on a track, you should look into whether either pan is a true baffled/trap door road race pan, or whether it is simply a stock-style unbaffled pan. Also, you may know this already, but there is a difference between road race baffles and a windage tray/crank scraper setup (which I hope the engine would have for the price). My best guess is that both pans are unbaffled, but I don't know and the FRP online catalog doesn't say. I have read on this forum, from a very knowledgeable racer, that there is no need to run a Fox Mustang, double-sump style pan, such as the rear sump pan on that engine, unless you already own one. Here is that thread: http://thefactoryfiveforum.com/showthread.php?6936-Oil-Pan-Question

The engine needs more oil when accelerating so rear sump....period. Especially with a 427 as all the oil will end up toward the rear of the pan it would be good to have the pickup where all the oil is. If you lost pressure under hard braking it probably won't hurt the engine.

If you plan to run sticky tires for more turning capability then a baffled pan like a Champ pan or armando will keep oil to the sump in a turn.

I have autocrossed with the champ pan for 3 years and they work great.

Thank you for the input. I thought the rear sump would be best because of acceleration but was not sure if there was something on the car that would require on option vs the other.

As far as the car is concerned it dosen't mater. there is nothing under the engine.

I agree with both Marshall and Chaz!??

The point that you need to focus on is, whether or not the sump has an internal baffle system designed for road racing applications. If it does, the system is designed to use what ever sump location the pan has.
