Just curious if anyone has a quarter mile time, or maybe a 0-60 time for a 96 F350, Extended Cab, short bed 4X4 w/ 4.10 rear and a 460/auto? 33nch tires, cat back, fairly stock but zippy.

I got a bet going and no place to run our trucks on a track.

Thanks

 

I doubt seriously that it will beat your 6.0L

 

I know, but he thinks it will, and I got a 6 pack on it...

 

I've heard reports of 6.0's running in the 15's at the strip, that's pretty quick for a 7700lb. truck.

 

I heard that too, but what about the late model 460?

 

1991 F-250HD 4x4 regular cab : 16.91@86.2mph
EFI460(230hp/390lb./ft. of torque)
E4OD/4.10:1 axle gearing

1993 F-250HD 4x4 regular cab : 17.40@76mph
EFI460(230hp/390 lb./ft. of torque)
E4OD/4.10:1 axle gearing

1997 F-350 4x4 Crew Cab longbed: 18.85@75.5mph
EFI460(245hp/400 lb./ft. of torque)
E4OD/4.10:1 axle gearing

1994 F-250HD 4x4 regular cab :?????????????
Stock 245@4,000rpm/400 lb./ft.@2,200rpm

Now : Vortech blower(6psi of boost), aftermarket cam, Borla headers, open element K&N filter, Motorsport ignition wires, MSD with timing control, aftermarket "chip", true 3" dual exhaust with twin cats&Flowmaster Series 30 mufflers. 420hp@5,000rpm/577 lb./ft. of torque@2,500rpm. It came stock with a weak-kneed E4OD(just had rebuilt $2,500), and 4.10:1 gears with a rear limited-slip axle. I'm the original owner. Just got it up&running again. Is it fast? YES!

 

Put pics of your blown 460 up!!!!!!!!!!!

Impressionable minds need to see!!!!

 

You running mass air on that thing??

Nope, it's still factory Speed Density. Converting it to a Mass Air system is on "the to do" list. Right now, I just got it up and running again. I have some pictures of the supercharger installed that I took back in September of '99 when it went on. I'll have to find some decent pictures of the truck, or take some new ones, and create another gallery.

 

I know a ton of guys that are chomping at the bit as far as how to do this with speed density. I don't know of anyone who's been able to get much more than stock level of hp/torque out of that system. It just isn't as flexible as mass air. Surely there is more to it than just a chip. Please let us know!!!!

Vortech system for my truck ('87-'95 EFI460) stays with stock Speed Density system.In the kit they provide a FMU(fuel management unit), which helps provide adequate fuel pressure. It also comes with an MSD with timing control. You can adjust the timing from inside the cab by turning a button. My EFI460 has much more than just a chip. It ran fine before the cam swap. The cam I chose was a Crane grind with the exact specs as a EFI460 truck cam which Ford Motorsport SVO(now Ford Racing Performance Parts) offered, which was said to work with Speed Density. Their part # was M-6250-T460, but I don't think it's available anymore. The Crane cam specs are the same (204 intake/216 exhaust @.050" and .487" intake/.519" exhaust). When I contacted Crane Cams, told them the year, computer system, and upgrades I made to my EFI460, this is the cam they suggested. "It works well with supercharged applications." Couldn't use stock springs, so I also got their suggested valve spring kit, and timing chain kit. With the cam, it still runs good, but I'm suspecting that the off- the- shelf chip needs to be replaced by a custom chip. Right now, I'm just trying to work out some minor bugs 'cause it has been sitting for a little over a year. The stock E4OD didn't like having such a powerful 460 in front of it. Now we're back on the road, but it's time for new plugs, wires, and an oil change before we're really ready to go. I'm thinking on trying out a custom chip before trying to convert it to a Mass Air system. From what I was told about Speed Density EFI460s, you can upgrade the exhaust & air intake systems with no problems, but it's when you start talking going with a "big" performance cam and/or aftermarket heads that you'll run into problems. If you took a stone stock EFI460, and installed a supercharger kit to it, with the Speed Density system in place, it would work fine, but you'll need the FMU, and MSD with timing control to do so. I've had my 1994 EFI460 pickup since it was new, and I've tried just about every trick to extract more power out of it. It's a learning experience.....for lack of some choice words. I've written every aftermarket performance parts company asking for EFI460 pieces, but they all said 302&351 trucks are more popular, hence they cater more to EFI smallblocks(which I can't argue with, I've got a EFI302 Bronco-my next project-which is my daily driver). Funny thing is my EFI460 pickup started out as a "daily driver" nine years ago. I think the whole thing sorta snowballed into this "creation" I now have. I could still use it as a daily driver, but when you're into the throttle a lot, you basically can watch the fuel gauge move. I love the power, though!
