Default 1994 Ford 460 mild performance upgrades

Hey all,

I just picked up a 1994 Ford Club Wagon with a 460 in it. I have a couple of questions about it. It's completely stock.

#1: What are the original HP and Torque ratings for this motor?

#2: What would some mild performance upgrades be? I could use some suggestions to get into the 300+ HP range, and also the 400+ range. Also, can I do this with the fuel injection, or would I have to replace that with a carburetor system?

I'm looking at upgrading the exhaust right now, but not sure really where to start. Thanks much!

-Pat

Stock ratings are 230hp / 395 ftlbs torque, I think. What I've read/heard s that the exhaust should be the first area to work over, a single 3" or 3 1/2" catback is a good start. Headers are next, I've heard that headers and exhaust will get you up near 300hp. I've got a single 3" behind my cat, and some shiny new headers are sitting in my garage waiting to be installed. Porting the heads and a slightly bigger cam are next for my truck, I've already got the cam from RHP, the cam and head work should get me over 300hp and thats where I'm gonna stop. 400hp is probably going to be hard, unless you ditch the EFI, that's not an option for me in the Peoples Republic of Kalifornistan....

Good luck

Thanks for the info.

I've read through the horsepower chart and even the starting selection (275-300) is suggesting a carb.

I was concerned about the extent of switching over fuel injection to a carbed setup, in regards to the computer mainly. Or is that as easy as just getting a new chip for the van?

I don't know what complications you'd have taking the EFI functions away from the computer. There are members here who probably do know, maybe they will jump in here. Late model EFI info can be hard to come by, but the info is here, you just gotta dig for it. My project is moving along at a glacial pace but when I'm done I'll start a thread with my final combo and how it runs. Maybe we can get a couple of sentences in the "known good combos" section about the EFI truck and van motors..

The 93 and up heads actually flow much better than the original E7TE's so...

Start with headers and a good free flowing exhaust system like banks etc.

Free flowing air intake with K&N filter

180 degree high flow thermostat.

Bump ignition timing to 12 to 13 initial from the factory 10 btdc.

addition of an adjustable fuel pressure regulator to increase fuel to air ratio at WOT which with the factor fuel tables is in the 13 to 14 to 1 range. This is really the end of the easy bolt ons.

Ported intake manifold.
Mild cam upgrade. Must be EFI compatable.
EFI double roller timing set is not retarded but should still be replaced.
performance chip for the ecm if not towing heavy loads.
BBK 61 mm throttle body.


EFI HP specs from 87 to 92:
230 HP @ 3600 rpm
390 TQ @ 2000 rpm

EFI HP specs from 93 to 97
245 HP @ 4000 RPM
400 TQ @ 2200 rpm


Just doing the bolts ons should get you to 300 HP easily.
Internal mods to 350 HP at which point the factory EFI is near its limit even with a chip and higher fuel pressure via an adjustable fuel pressure regulator.

I recently did a motor home fuelie combo and the difference was night and day.

The air intake silencer's removal does not help much on a completely stock engine but its removal is very important on a moded engine.

Hoirsepower ceiling on the production EFI system is about 350/375 HP maximum - and that takes a bit of tuning to get there.
As Scotty said,
1. Free flowing Cat Back exhaust with headers
2. Low restriction, Cold air intake system with IAT sensor moved.
3. 180 thermostat.
4. Asjustable fuel pressure regulator for WOT fuel; (46 pounds checked without vaccuum is about right).
5. A small EFI compatible, performance camshaft.
6. port the intake manifold.
7. belt pulley changes.

EDIT: That's about all - unless you get into changing a lot of other stuff; (injectors, throttle body, bigger camshaft, ported heads with big valves, software, etc.)

Alrighty, I have a hole in my radiator so the first performance upgrade is going in! Along with a new radiator, and I'm thinking of even getting an aluminum radiator for the weight difference, is: a 180 degree high flow thermostat.

What is the difference between stainless steel, copper and brass? Summit racing has 2 thermostats I'm looking at. One is all stainless steel and the other is stainless steel, copper, and brass. I'm assuming the all stainless steel one would be best, because of the rust protection? Is there a huge difference in weight?

(Ya I know I may be nit picky, but I want the best for my baby).

Edit: Also, I've done some additional research, and it looks like just installing the 180 degree thermostat will cause the engine computer to adjust the air/fuel mixture to run a bit more rich. So I have a couple more questions here about this:

Is there really that big of a difference in the 15 degrees in regards to engine performance, air/fuel mixture, and MPG?
Is there a way I can adjust my computer to "like" the new 180 degree thermostat without installing a chip, or new computer?
If I put in a high flow 195 degree thermostat, would that be the easiest option, but at what performance suffering compared to the 180 degree high flow?

I am Currently working to get 96 box can with a 460 and adding a five speed to replace the 460 and 4 speed in my 86 f350. Does anyone know if the EFI system will without the smog pumps and catalytic converts and emissions bull? I haven't got to dig through the engine yet does anyone know if the were using disturber in 94? I use my truck a lot for work so I'm trying to keep it as efficient as possible.
