Default 427 side oiler

Greetings, I want to mount a 427 side oiler for my cobra, I have the block and some low riser heads, I live in the tropics very hot, what combination can I use so that the temperature does not rise, thanks

I have a 427 SO in my Cobra with a radiator and oil cooler in central California and do not have overheating issues at all.
If there’s something you’d like me to check I can share it with you.

I would definitely run (2) Puller Fans to get your radiator cooling efficiently. It replaces your regular fan, and comes with a shroud.

The OP needs to give a ton more information about his build/Cobra to receive focused advice. Otherwise we're pretty much shooting in the dark. There are many variables.

For my 2 cents on this thread, the pulling double electric fans are a great idea, add an entire bottle of waterwetter, I was able to bring my temp at least 8-10 degrees cooler in the NYS summers. Also make certain that your alternator wheel is not impacting on your fan performance, I had to get a smaller diameter pulley for mine. Other than that. get used to the idea of the 427 SO wanting open roads vs heavy traffic.

If you're really looking to lower your boiling point as well, do not run water in your cooling system! There is a new product out there called "Evans Waterless Coolant". Jay Leno showed the product on his site, and a friend of mine is running it on his Nomad with his LS3 engine. It's non corrosive, and you will never need to change your coolant ever again. There is a flush product if you have run water and Anti-Freeze, and then after you have ensured all the water is out of your block & radiator, simply add the Evans Waterless Coolant. You can google the product. Good luck!

Is it good for aluminum?

Suppose to be great with Aluminum, as it's not corrosive as Anti-Freeze is when it sits too long.

OP your engine operating temperature will not be affected by the oiling system you choose, side oiler or top oiler. The oil system only determines how lubricant is delivered to the engine's internals.

Your engine operating temperature is going to be determined by your cam choice, how you phase it to the crank, your ignition timing (initial, total and how fast you bring it in), compression ratio and how the finished engine is tuned.

Once you have completed your build and before or after you install it in the car you would be doing yourself a big favor by taking the engine or the engine and the car to a dyno shop to get tuned. In the car may be the better approach because you will be using the cars fuel system, cooling system and engine management system, if you choose to go EFI

If you opt for carbs (like most of us have) the proper fuel delivery will likely require more than the simple jet and power valve changes most of us are familiar with. You could end up in the emulsion tube and air bleed adjustment sandbox and your best friend will be the guy tuning your engine on the dyno and the oxygen sensor he places in your exhaust.

If you just put it together and SWAG (Scientific Wild Ass Guess) the tune you might get close but then again you might not — more often than not the answer is the might not side of the street. If you go to a shop that specializes in tuning carbureted engines he should have all the carb fuel delivery components you are likely to be needing.

Many dyno shops today specialize in EFI managed engines. There is a very real chance they will not have adequate familiarity with carbureted engines (or air bleeds, emulsion tubes etc) to deliver on the tuning promise for you. You need to find a shop that specializes in carbureted engines. That will not be easy but it is essential.

In the end you will have a properly tuned engine that has gobs of torque and power and good street manners.

A good shortcut on all this work is to go to Bykins or Kraft and buy the finished engine from them (you can ask them to use your block if that's important to you). They not only have two truckloads of experience but they have run their configurations on their own dynos, tuned them on those dyno and produce well tuned, well mannered, high power engine packages for guys like us.

Parting thought, medium riser heads are not hard to find. Low riser heads will leave you disappointed in the power department. Low riser heads will be less expensive but not a lot. Reach higher, you won't be disappointed. Either of the two engine builders can easily help you out in the head sourcing department.

Throwing caution to the wind and taking a DIY shot at this is probably not a very good idea. In the end you will spend more and get less — when you didn't need to.
