302 engine swap in a 1995 GT water pump problems

[astar]

I am swaping a newer 302 from Ford Racing into my 1995 GT. The only real problem I seem to have is that the new engine has a reverse direction water pump where as the stock engine has a clock-wise water pump. The surpentine belt will not fit and needs to turn the pump in the oposite direction. I heard that I need a flat pulley set that will replace the stock one. I also need to run a supercharger on this belt, but that probably makes no difference.
Any ideas on how I can solve this problem? If I do need this flat pulley set, can someone tell me where I can tell me how to find one?

I have a Ford Racing crate motor in my 95, i had to change the timing cover for my original 95 one as the one fitted is totally wrong for these. I also removed the fuel pump eccentric from the cam and ground a bit off the cam dowel, to make sure there's clearance, the 95 cover is very shallow.
Once i had my cover on i used a new 94-95 pump and everything was fine.

Was the pump that you finally used a reverse (counter-clockwise) pump? I haven't actually seen the engine being dropped in, but the shop called me and tolled me that the water pump pulley is not in the same place as the original. I assume the reason is that the stock water pump is a clockwise pump.
I ordered a 5.0L/302 – 340 HP GT-40 ALUMINUM HEAD FORD RACING PERFORMANCE CRATE ENGINE. Is the engine you used simillar?

I have exactly the same engine, yes its an earlier water pump thats fitted to the crate motor.
You will need the stock pump which is counter clockwise and of course the original timing cover :

What size injectors are you going with, also if you need any help with anything ask away, i've played about with just about all of it.

The supplier (PowerTorque in Coventry,UK) who sold me the engine wrote that this is a newer engine with an anit-clockwise pump. I assume then that I can use this pump if the stock one is also anti-clockwise. Is the stock one (a 1995 5.0) anti-clockwise?
If the direction of the water pump is ok (the stock was anti-clockwise), the only problem is that the water pump is on a different plane than the remaining pulleys. That is the water pump pulley is farther forward. Maybe there is an adapter I can use to move the pulley surface rearward?

The injectors or 42lbs. I have learned not to use the stock 19lbs, because I had a supercharger with an old rad. The engine overheated and the lean fuel mixture caused detonation which damaged the stock engine. That is why I am replacing the engine
I thought that transferring the supercharger would be the real problem, but it seem this water pump is.

Well there's a few issues why i would'nt use that new pump, its also longer, and does'nt fit the serpentine pulley, its not a newer engine, its designed to fit older Fox bodies even tho its "new".
The sump fits ok, its the same, but you cant use those nice valve covers without using a 3\8th spacer, and grinding of the manifold at the egr etc.
I'm only in Manchester, just pm me and you can ring me if you like on my home phone.

Thanks a lot for your advise. I am still at work so can I call you a bit later. I also want to talk to the shop installing the engine before I contact you. There was some problem with using the old timing cover ...

 

[95-stang]

They probably are'nt really trying i bet as its not fitting dead easy, ok i'm a mechanic by trade, but i did mine at home.
There should be no problem fitting the old cover if they remove the fuel pump eccentric and a bit off the cam locating dowel.

Like he said. Once you swap out the timing cover and replace the water pump with a 94-95 water pump, You should be go to go. Oh and you need to reuse the oil pan from your old engine too. The GT40 motors oil pan does not have a hole for the oil level sensor. So make sure they use the old oil pan.

 

[95-stang]

That could be, mines an export model and the oil level sensor is'nt fitted in my pan, its like the low water level sensor, it does'nt have that either.
You could just get away with the new pan if its an export Mustang.

 

[astar]

My stang was purchased in Canada. So I will probably take your advice and use the current oil pan. Thanks for the advice
Well I hope things go a little quicker know. This is the third set of modifications I'm doing (if you include the paint job), and I have been waiting for the parts to arrive and go through customs since the start of this summer.
It would be a great to finally get to drive it again.

 

[95-stang]

Well lets hope your driving it soon

You may have a problem as the new engine uses Ford roller rockers, and the stock valve covers will not clear these.
The Ford Racing covers that come with the new engine are fine, but you will be needing a 3\8" phenolic spacer to allow the upper intake to clear the valve covers.
Unless you can find some Fox body valve covers over there this is how close it is.

 

[astar]

Well it looks like I do have a problem with the valve covers. The intake manifold will not clear them, although the mechanic tells me he needs more like 3-4 (about 1 1/2") cm not 3/8". He also had to remove the oil refill because it is in a different place (under the intake on the manifold). He feels that the vovers can't be much lower than the ones from the new engine because rocker arms will not fit. Does this all sound familiar?
Another problem is that even if he were to lift the manifold by 3-4 cm, the hood would not close :crying:

How can I get around this problem? Where you able to get the ford racing valce covers to fit under the stock hood with the intake manifold?

An intake on the hood would solve this problem and provide cold air to the supercharger intake which is currently located just above the exhaust headers on the driver's side. The problem is I don't want the car to look tacky and a new hood is a large expense :dunno:

 

[95-stang]

Well i've been there and done that i'm afraid.
What you need are Fox body valve covers, Paul on here did have some for sale, they fit over roller rockers, the oil filler just misses the intake, and you dont need a spacer.

You will need to modify the egr tube lengthwise to suit.

Here's a rundown of how they fit:
http://www.sn95forums.com/forum/index.php?topic=28155.0

As you can see on mine, it just clears filler wise:

There probably are other covers that will fit, if you have the time to track them all down and mess around with them.
These will fit pretty well straight on and polish up etc, what Intake are you using btw?
If your running a blower no wonder your using bigger injectors.

 

[astar]

I am using the stock GT intake. Is it taller than the cobra one you are using ?

Is thera a way I can use the FR covers the engine came with? Are they really so tall that I need an extra 4 cm ?

And another question which may sound pretty obvious. What exactly are fox body valve covers and how are they different from the stock mustang GT covers?

 

[95-stang]

The Cobra [i use] and your stock intake are about the same height but yes the covers are tall.
To use the Ford Racing covers you will need to use one of these with the stock intake:

Its 1" tall, but your intake will just clear the hood even with it on, it may rub the insulation, but you should get away with it.
You will need to knock out the existing filler neck, weld in an alloy bung, then drill at the front [you will need to mock up for this] and fit a push in breather something like:
http://store.summitracing.com/partd...3408&N=700+4294888301+400304+115&autoview=sku
You can pull them out and use as an oil filler.

you can just see the breather behind the intake, this is how mine was.
There's still a bit of grinding to do here and there, and your egr will need extending just over an inch.

 

[astar]

Are you sure the hood will fit with a 1" spacer? Previously you wrote about a 3/8" spacer.
Also, is the breather you suggest on for oil filling, or is it necessary for another reason too?
What needed grinding? The covers or other parts?
Lastly how was the EGR extended?

Sorry for being so trivial, but I need to provide the guys doing this for me as much info as possible. Also, once I order something from the US it costs more to return it than to buy again (75% of the price is shipping and duties ) I need to be sure before I buy.

 

[95-stang]

Originally i had very tall Moroso covers, which needed a 1" spacer and the top of the intake rubbed the insulation.
This was too close, so when i got the motor with those FR covers, which are a lot shorter, i ran the Cobra intake with a 3\8th spacer, which gave me much more clearance, but this is Cobra, not stock.
But to get it all to fit i had to grind the aluminium on the underneath of the intake where the egr fits and on the ribs of the FR covers and a bit near the idle control valve.
The breather is just that, and the pipe from the breather went into the intake as does the stock filler, and it doubles up as a filler for oil.
I cut the EGR at its straightest point, and welded in some suitable tubing its part skill, part guesswork.
I have never tried fitting a stock manifold with spacers or aftermarket valve covers, but overall the stock intake is very close to the 94-95 Cobra dimensions.

There is no real spec or exact measurements for this sort of job, you have to keep assembling and then modifying, i blame Ford for their intake and hood design which gave no thought to all those who want to modify things.

A shame really as i have the spacers for a Cobra intake, but not stock.

That would give you plenty of valve cover clearance, and still be well under the hood, less grinding of everything, if any.
