New Member - future fox body project

[ziggy75]

Hello everyone. I am new to the forum. I have owned several Mustangs during my lifetime. I have owned two fox bodies and a few sn-95's. I've been researching for some time now for the purpose of doing a DOHC swap into a fox. Not sure what year yet. They are all great in their own way. My main interest is either a 5.4 Navi or a 4.6 Teksid and build from that. I know it would be much easier to just drop in a 4.6 but I like to make things complex and that is why I am leaning towards a 5.4. I am sure I will find plenty of info here.

Welcome to the forum. You will find most of the answers you're looking for right here. You'll find several 5.4 and 4.6 DOHC conversion done or almost done. I can't help much with the 5.4, as I've never done that one, but feel free to ask all the questions you want. Someone will likely chime in.

Thanks for the welcome. I sold my 94 Mustang of 12 years last July and miss it terribly. I had swapped in a 351w and loved the torque that thing made. It was all fuel injected and tuned myself with Tweecer. Gas mileage was ok but could have been better. I have heard many people argue that the mod motors are far too expensive than the pushrods. I use to agree with them. That is until I began pricing parts. I had roughly $800 into my shortblock, $1500 in AFR heads, $600 into intake, $300 into a cam, $200 or so for throttle body and so on. Anymore, you can purchase a Mark VIII and make a few changes to make a decent 300 horse. Not to mention, if I went with a 5.4 navi, or even a used 5.0 DOHC from an f-150. The parts that were used with these engines are far more efficient than what the 5.0 pushrod used. I am not knocking the pushrod because it does serve its purpose. But if I am going to purchase all these parts for a pushrod, I can have comparable parts that are OEM. Only big set back is forging internals. I do believe the pushrod setup is more cost effective. I do feel that in a few years these forged parts will drop in price.

Here's a forged crank you could probably have fairly cheap http://www.ebay.com/itm/4-6-Ford-Mu...Parts_Accessories&hash=item417b3cf0b9&vxp=mtr

There are always parts floating around out there that can be cleaned up and put together. I built pushrod motors for years before I decided to switch. The parts for the 4 valves tend to be a bit more that the 2 valve motors, but not that much more.
