Ford V10 height problem - is dry sump a fix?

just dreamin · #1 (**permalink**) 11-14-2011, 05:04 AM

My ford v10 wont fit under my cobra bonnet (hood for US) because it is too tall. I can lower it 4" if I dry sump it which looks like it will work. However I have some tech questions re oil circulation within the block. 1. Do I remove the factory oil pump and if so what mods are required in this area? 2. Where do I introduce the main feed from the external pump to the block and not have a problem with oil pressure/distribution? 3. Has this been done before and is there any special fittings reqd or available.
I have a full dry sump package available in my shed but not the knowledge to utilise it. As these motors are a rare item here its unlikely anyone in Australia would have experienced this issue in the past and I hope there is help out there somewhere, thank you.

Just dreamin,

Aviaid has been building dry sumps for the 4.6 and 5.4 Mod Ford motor for some time. Here is a link to the prod and home pages:

what motor is it exactly?

The 6.8L V10 is just a 5.4 with two more cylinders tacked on (do the math) and the oiling system is the same. Other than the pan, the dry sump system for the V10 would be the same as the 5.4 V8. The 5.4 and 6.8 share rods, bores, bore centers etc. This was the "modular" motor sytem, the block could be machined on the same line and equipment thus "modular". Initially there was to be 90 degree V6 version also.

John, I think you're seeking the wrong kind of help, I have organised the men in white coates and they will be there shortly.

Thats a brave move dumping a 6.8 V10 in there

gotta see it when it's finished.

Cheers

Will the gearbox bell housing be too low if you drop it all 4 inches?

Jason thanks for the link, I will be following it up, Slipry thanks for the kind words of encouragement, Boxhead I looked at that and it will be the lowest point,but But I can modify the bottom and flatten it off. Also the block comes down all the way around the crankshaft (6 bolt mains) so a 2" sump is still quite low anyway. Now I thought this was going to be a low key enquiry and not be noticed however as dave points out the man in a white coat was here and said it would be easyer to road register this motor than the 460 in my robnel. No this motor is bound for the track and hillclimbs as what else could I do with something that made 680 hp and 600ft/lb of torque on the engine dyno. It also made 500ft/lb at 2500 revs and runs on pump gas.
This motor was built for ford Aust and went into a year 2000 mustang convertable to showcase the imports of same car into Oz. It was supercharged and intercooled, fuel injected by motec, manley rods, JE forged pistons, custom steel crank girdle, ARP bolts, O ringed with copper gaskets, Blah Blah Blah etc. I am hoping to enter it in street class at the nationals There was an article on the car in Zoom magazine and also on AutoSpeed - Smoking Horse on the net.

I remember seeing the article on that mustang. It was a burnout car from memory with independent front wheel brakes so they could apply the front inner wheel brake and pivot the car around it when doing donuts.

The ford V10 motor is from the truck division much like the Dodge Viper V10 started out in the Dodge Ram. It's pretty heavy compared to the Viper V10 motor as it runs an Iron block (truck motor). I believe the first Vipers had the Iron truck block and then switched to an aluminum one.

Should still be a cool thing to see under the hood.

Wasn't that the engine they put in the "Daisy" prototype ??? The "NEW" Ford version of the Cobra.

No I think you are refering to the prototype Cobra built in 2004 fitted with the dry sump all Aluminium 6.4 litre V10

Just a suggestion but you might try contacting Bill Emerson who is on CC. He used to be listed as Emerson Motorsports and he built a Cobra for a guy here using the V-10 and I am pretty sure that they used a dry sump in it but that was some time ago and I am not positive. Regardless he could tell you what they had to do to get everything in and clearing ok.

Be careful with the heads on that motor. The stock aluminum heads have a history of blowing spark plug bosses right out of the head.

Agree.

If you drop it that far, you'll need to consider flywheel diameter and the corresponding bellhousing, driveline angles, extractors and the rest of the exhaust system.

If you can run a smaller flywheel, how then to start the engine?
