Need for Speed!

This is my work in progress thread to my 1977 F150. I purchased the truck as a stock 2wd swaped 351w / C6 truck with a 2.72 9" rear end. The minute I bought the truck I knew I was going to swap it to EFI but it needs to be done affordable as this is going to be my run around the shop work truck. I also know overdrive is about necessary these days so that needs to be in my upgrades to gain more power and fuel economy. This truck will be a daily driver so no antique tags for it. It will need a Virginia state inspection when complete(no smog here). Here is the plan: Engine: 351w roller block, Explorer GT40 heads (.5" head bolt holes) Intake: Knock off PP 351w mustang intake Fuel system: Mid 90s F150 factory rear tank setup. Ignition...

Had a crazy thought for an EV conversion project... to find an AWD or 4wd Explorer with a busted engine, then get an EV West kit. Trouble is.... That kit can put out 1000 lb-ft of torque, or in layman terms, over 3x the 4th gen v8. I could obviously limit that with varied power input, or use a less powerful motor set, but I'm wondering how close I can get to that number without shredding more than tires. Anyone else pushing the torque limits of the AWD or 4WD system with conventional engines? Are there upgrades that are easy and common in order to beef these up? Edited to expand to 4WD as well. I am not dead set on AWD.

I recently hrydrolocked my motor(4.0 ohv) and believe I bent a rod because the engine won't turn over by the crank with the plugs removed. So I figured it would be a good opportunity to do a full overhaul on my 300k+ mile motor. And while I'm in there, may as well go all out! So my plan from reading posts from you guys, is as follows: my 95tm block bored as little as possible, comp 422 cam, my 95tm heads checked and milled for 988 springs by a shop, and mildly p&p by yours truly, along with the lower intake, 91tm pistons to up the compression, New crank, bearings, all seals and all gaskets. And of course a snorkel to prevent this happening again. I have a few questions that I need help with though. I have read that the 91tm pistons are...

Hey! :D So I just read alot of threads of people that has sc their ohv explorer. I have wanted to do it a long time now. But not sure what i need. :confused2: The List i have come up with to now is: -Supercharger M90 -New injectors -New MAF -New fuel pump -Intercooler(if i go over 5psi??) -wideband -New drivebelt -New MAP -Intake manifold adapter for the SC -New gaskets I don't going to rebuild the engine any time soon. So looking at a small power increase. Maybe 180HP or so? :rolleyes: The Trans will hold as long as it does... But will add coolers on it. Just in case, maybe a auxiliary filter too! But the truck is a 1995, so i will have problem with tuning it. So how is a smart way to deal with the OBD1? :dunno: The truck...

So ive recently decided to cam swap my explorer, and messaged comp cams about my idea, and had them recommend me a kit (k35-349-8 xe264hr cam) including guide plates, rockers, springs etc. I have a question about the studs, will i need extended studs, or will my stock studs work? Im not very good with cams and cranks, so this is still kind of new to me. Any suggestions would be great. I have read that the studs were extended to 6.3s or somewhere around there, but they also had some headwork done, will i need the same even though i have stock heads?

Well guys been super busy and had parts to do this sitting around for awhile. Fortunately enough my timing cover gasket went from no leak to straight peeing in a 2 mile drive recently. Here is a few notes and parts I used, I'll add part numbers and update original post wen done... -Comp Cams 35‑349‑8 Xtreme Energy Cam -Alex's parts gt40p springs -Alex's parts 6.305 extended pushrods (figured this out after cam was installed and stockers are WAY too short) I already had a few supporting mods along with 1.6 roller rockers and roller timing chain setup on the truck when it was built. Put about 15k hard miles on her in 2 years and she sure needed a little cleaning. Rps20160914_204634 by boominXplorer posted September 14, 2016 at 8:54...

Since i plan on running a supercharger and about 5 psi, I will most likely need a tune. I plan on using the moddbox kit and they also offer an online tuning service but I wanted to see about maybe getting a dyno tune to dial in the fine details. Does anyone know of a good tuner in Southern California? I live in San Bernardino but am willing to drive anywhere from Santa Barbara to San Diego. Also, what is a general cost of a dyno tune? That might also be nice to know haha

Finished up my m90 and just ordered some new oil for it. Should be good to go. In preparation for actually installing a supercharger, or a turbo, I'm sure everyone wants to add some gauges. I think boost/vacuum and AFR are pretty important. I would like to have some input from others on which vehicle components should be monitored when going with forced induction. I personally plan on using two PLX DM-6 gauges, which can connect to 16 sensors each, but I want two so that I can simultaneous display boost and AFR. I like that they are really thin and plan on installing them on the gauge bezel; they should only cover the PRNDL Haha. I don't want this post to be about which brand is best. I mentioned my plan to keep everyone updated with...

[Edits to follow - work in progress] Where to find the 4.0L SOHC: 1997-2010 Ford Explorer/Mercury Mountaineer 2001-2010 Ford Sport Trac 2001-2010 Mazda B4000 2001-2011 Ford Ranger 2005-2009 Land Rover LR3 2005-2010 Ford Mustang 2006-2010 Ford Sport Trac For us, this story begins in 1997 with the first of the 4.0L SOHC engines being sold in the Explorers. Ford used a "Rocker Arm" part number F77Z-6564-AB in the first of the SOHC engines (1997-1998ish), which was very similar to the follower used in the 4.6/5.4L 2v and 4v motors, but with no oiling hole. Original 4.0L SOHC "Rocker Arms" (cam follower) This is the oiler feed line [part 6578 above] and this is an indicator of an early 4.0L SOHC (1997-2007ish). These engines have...

so jds been nagging and nagging me to get away from not having any boost. he even set me up with contact info for a vortech kit, and after waiting for a month or so to get things straight with money, i bought it from a guy. he bought it used and never installed it. just reshipped it to me the way he got it. so i may be missing a few nuts and bolts. hopefully a couple people on here can point me to what might be missing and any extra tips with it. im gonna try and email vortech and see if i can get an installation guide or parts list. so ill need new pipe boots, a couple are torn, all of em are used. and wrap the intake pipes. engines gonna be stock compression 94 block, new pistons, maybe sohc pan, 422, 93tm heads with si valves, 988...

Parts and Info for my Turbocharged 4.0 from my thread http://www.explorerforum.com/forums/showthread.php?t=426937 This list is the basic parts (major items) I used to end up with a turbocharged 4.0 OHV. I hoped this could help consolidate information from the thread and from the research I've done to this point. This setup has resulted in great drivability allowing me to keep up with modern traffic. Boost comes on fast if you want to get on the go pedal but it also allows you to cruise out of boost at around stoich or slightly leaner programmed/tuned appropriately to do so. This set up would allow you to run 7 pounds on a daily driver, to this point in time, safely and reliably and I can pass obd2 emissions testing. Smaller...

Hey guys, I'm finding it difficult to find anything on this so i thought i would just start a new thread. I'm new so I apologize for anything i'm about to say that sounds ignorant....BUT, Is there anyone who knows about the dangers of using a chip or removing the governor(the thing that ruins your fun when you hit 110 mph) as far as whether the axles can handle it or if anything has been know to catastrophically malfunction...I wanna go fast but I just don't want to die the first time I do. What should i upgrade first? I'm ordering some basic upgraded parts(intake, exhaust, injectors,...); I just want to know if there's anything i should add to the list.

About a month ago I got Nitrous on my 1994 Explorer and I've been waiting to try it out at the track. Wednesday was the first Test & Tune night at Bandimere Speedway. Currently spraying 50 HP with NGK TR6 spark plugs. After a couple runs the spark plugs looked great. Probably gonna try a 75 shot sometime soon. I gotta thank user jd4242 for his help on getting the kit installed. Up here at 5800 feet above sea level, cars run a lot slower. With only a KKM intake and Dynomax muffer my fastest run ever was 19.30 at 70 mph. Here at the time slips Quite a big drop in ET and good MPH gain. This kit was definatly worth it whether it's racing or just messing around on the streets. Video of me at Bandimere Speedway...

I'm wanting to put a 347 in my 97 5.0 should I stroke the motor thats in it or drop a turn key carb 347 in it?

Does anyone know if someone makes a 3" mandrel exhaust kit for our trucks? I need at least 3" for my '02 Sport Trac 4x4 due to running 9lbs boost from my supercharger. Thanks in advance
