Thanks. Stock water tube size. Looks like it’s just part of the original markings.

I just pulled my intercooler core and found the following engraved on it. Appears to read: CO396A5 possibly CO396AS? 717874-003 NOV-21-12 Then the core seems to be sealed with a whitish sealant to the frame. It still has all the factory stamping so not sure if this is due to a modification...

Your question will get more replies in the terminator section if you want to post there However, Have your mechanic look at all the bushings in the IRS for degradation of the rubber, IRS knuckles having torn boots on the upper joint as well. Anything rubber needs to be looked at for...

You have pressure at the schraider valve on the fuel rail?

Looking at HCMs and the UPR / eBay one is less than half of the others. I didn’t see a significant difference between the UPR and MMR. I know others such as Wonder Racing and others are different but for the ones that are like hockey pucks with a tab for a bolt is there actually any...

Actually it’s only plumbed into the intake for emissions purposes and to stop the engine from getting a mist of oil coating it in a production car. They want to burn the vapors as they have hydrocarbons in them rather than release them. Venting with a catch can on a “normal” motor saves you...

I can see the female plug being able to be found as there are plenty of returnless cars in the Ford lineup. My concern is the female connector to connect the original wiring harness connector to the new harness you are making. I would appreciate the years of the F150 that the plug may come...

I would appreciate the write up on wiring the dual FPDM as well.

drill a couple small holes on the thermostat skirt to let any trapped air past when vacuum bleeding. FYI usuallly a smal bubble doesn’t cause the slow overheating you are talking about though.

You answered your own question if you have power on the wiring harness at the pump hat and applying power at the pump that runs. The connector has an issue. You could also pull the harness at the other end and see adding power to the end near the fpdm will energize the pumps. Looks like...

Best improvement for handling before you tear into the IRS is to add full length subframe connectors. What is the purpose or intent of the improvements? Tightening up street driving, autocross, weekend track car, quarter mile car? You may want to make a couple calls to Kenny Brown and...

Do you hear the pump prime when you turn the key? I always wait till the prime stops and then turn the key the last bit to engage the starter.

I ran out of pump at 450 using a DW300 which is supposed to be 340lph. I would not expect a 260 ish pump to carry 450hp. You using the same injectors? Duty cycle would be irrelevant if not on the same size injectors.

Please tell me that was an attempt at a joke…. It’s a sales display. Private stalls there. The public toilets even have a music feature to cover up any additional noises……

OEM ford

Go look at the old gun debates on this stuff. It ended up being mostly vegetable or coconut oil iirc

You have 260 lbs of 9mm in your spare tire well?

Forgot to mention start looking through old posts here about the swap and the mach 1 forum had a ton of posts on it too iirc.

You have all the front accessories from the 03 motor? Alt and bracket, water pump, pulley bridge etc? you could run the same tank but if you leave a stock 01 pump in it expect the motor to last about 4 seconds under full throttle. If you have the 03 fuel hat with dual pumps you have to tear...

If you use the original dip stick the oil will be below the seam where the pan and block meet and below the crank. Our motor has the crank not swinging below the block. Since the crank can’t airate the oil if it’s below the block / oil pan line you can fill it to the normal dip stick’s reading...

Could you list the things you would do differently? It would be nice to see the issues based on your experience. Hopefully doing the swap soon myself.

The factory boss 302 rods were a common upgrade when they were cheap from ford. Ford caught on and raised the price so most go aftermarket now. They are supposed to be good to 600 hp iirc.

Have a procharger now on mine. Fun as the revs go up and tuned safely. No torque hit down low so a little easier on internals iirc. But after this I have a forged long block and an Eaton swap sitting in the garage for when I have time to get it all done. If you want 425-450 a used...

NOS is New Old Stock. A new part that has been typically discontinued by the manufacturer but is still new in box. Differentiates between new and available and new but unavailable. Muscle car parts that were NOS were a big thing on a correct restoration. Usually meant the date codes were...

With a 4K budget you are looking at a used procharger kit and tune. Stay at 400-425 and the motor under 3k will be no more stressed than it would have been NA. If you don’t drag race and it’s a weekend cruiser with conservative timing the motor will be fine. Compression and leak down test...
