My last build was with MMR 4.75 stroker kit for my 03 Cobra with a gen 3r 2.65 VMP
Sounds like a good build! My marauder engine is an iron block with Manley stock stroke crank, h-tuff Manley h beams and CPs with stainless rings and the 2.65 on top. I went a little heavier on the rotating assembly but she wraps out nicely.

But if I were to go N/A without the larger bores I would at least throw a coyote crank and rods in there. Inexpensive high quality mass production components, kind of like a Chevy thing! So that is a win for mod ford rodders… not to mention the weight savings

I remember reading about using a coyote crank but at least one of the issues was the oil pump. I don't remember full details, but the coyote crank is not plug and play. The woodruff key and oil pump rings a bell. Do you have more information on how to modify a coyote crank for these 4.6 block?

Is that a big dog's ported intake?

Hope the kids are feeling better.

Upgrading to extended range senor. If using same tube does maf transfer need to be adjusted?

Like I suspected, I mixed up a plug. It's funny that two identical plugs are in the same area. I had the TCM in the wrong plug. As soon as I switched plugs, I had OD control.

I can't find any information online but I'm looking for a diagram on how the TCM is wired. From my understanding the TCM tells the ecu to turn the overdrive off or on via pin 41. Right now, I have no control of the OD function. I've been pressing my luck doing pulls with the OD on. I want to make sure the wiring going to the TCM is good. I had to do a heater core and I might have missed something putting the dash back together.

I have an aftermarket pioneer balancer that is balanced with the motor so I don’t want to swap for the explorer timing cover set up. I have a 36-1 wheel I can’t mount behind the crank pulley. Guess I’ll have to fab a bracket and use some shims for gapping the sensor.

I'm in the planning stage of doing the same thing for my SN95. Its easy for me to use the explorer timing cover because its basically the same as 94-95 mustangs. I was going to order this trigger wheel.

Great. Thanks for the information

Was thinking about this. If I used a 03-04 sedan ecu and wire harness. A explorer timing cover, 36-1 wheel from explorer and ls coils. What else would I be lacking?

youd need a hall effect vr though

best bet is eec v so u wouldnt need an edia module
03 04 luxury sedan ecu

So I've heard a couple people online say this and was wondering how true this is. If you decrease your fuel pressure the ecu will increase injector pulse width to keep commanded lambse . Likewise if you increase pressure it will shorten pulse width. Alway in context of unturned guys cranking up fuel pressure with adjustable regulator l.
