Why do head gaskets have much smaller coolant passages that the head and block? Is it to keep water pressure up? I thought they had sent me the wrong one, but found the original and it was same way.

I am wanting to run some aftermarket valve covers on an Explorer 5.0, but they most all come with a hole on each cover, as carbed engines use one hole for PVC and the other for a breather oil cap. EFI requires all air entering engine metered right. So how have yall plugged the extra on some like...

I heard a guy tell me a while back a Justice of the Peace can get a title for abandoned vehicles so I googled it. I am in Louisiana and found this document. I stopped by a Justice of the Peace the other day and the lady was very knowledgeable and said no problem. Just get the vin run and a...

I think I could do this all day. It will prolly only cost $$200 a gun in about 10 years the rate electronics keep getting cheaper. https://m.youtube.com/watch?v=Qjj6SadiJO4

Anyone got a 351 lower gt 40 they want to sell?

I noticed a 1996 351 e250 van and decided to pop this motor out. I didnt want the E7 heads or lower intake and ditching them let me pay just $110 for a short block. If I use it I will put some GT 40P heads on it and the Lightning lower with an Explorer EFI. Pulled the heads in the junk yard...

I am going to pull a Explorer motor and trans and was gonna leave the harness connected while pulling. Any advice on what needs to come home with me and where I can cut things and dont need? I am assuming I just cut the OBD2 plug a foot or so from the dash harness and bring it with me. I tried...

Can I use the Explorer flex plate and Explorer harmonic balancer together on a 351 and be good? Or do I have to use the 351 flex plate and get the balancer converted by DamperDudes? If I use the Explorer damper on a 1996 truck 351 serpentine, will the truck crank pulley bolt to the re...

Thinking of stroking a 5.0 and reading on some mustang sites where they talk about balancing is a must. Is this cause they are drag racing and spinning 6-7000 RPM? Or do 99% of people just assemble them like a stock rotating assembly and rock on down the road?

I was looking at sbf heads for a potential 302 upgrade and 347 stroker down the road. I found heads flowing from 180 to 250 on intake, and some of the heads had great intake flow but not very well on exhaust. Question is..... if I were to buy the better heads and put them on a stock explorer...

I like the looks of modern vehicles with a gray or black interior regardless of exterior color. Any of yall done the hard top, dash, door interior metal gray or black with a white, blue, red, green exterior?

I have been reading various threads on multiple websites about priming sand blasted metal. I have the underside of the tub blasted and it is either perfectly bare metal gray or has a very slight red in a few areas the gun couldn't blast perfect but those areas are clean. Some people are saying...

How much hp/air flow do the stock upper and lower Explorer/Mustang upper and lower efi intake max out at? Trying to figure out basically if I would be wasting money on a really nice high flow head if the intake cant keep up.

I obviously need to remove the center part, but dont have the key to put in there and insert the paper clip and turn. Should I start drilling and tear everything to hell and plan on replacing ignition switch, bezel by the time I am done tearing it all to hell?

How many upgrades like high flow heads, cam, and headers can the OBD 2 Explorer efi handle with stock injectors and computer?

I was researching a 1.9 VW TDI swap for my dad's cj and found this ax15 adapter. So this means we could take a 175 diesel torque 1.9VW turbo engine at 1700rpm, adapt it to a ax15, then adapt the ax15 to our Dana 20 and rock and roll. They have came out with a manual injection pump for these 1.9...

Any real difference in the ATK or Blueprint engine quality from summit in y'alls opinion?

Well most of us just bolt our heavy duty bumpers on and do not think about how easy it could get torn off when getting pulled out of the mud or in a wreck due to the minimal frame material after the 4 bolts. Here is what happen to a friend of mine when someone hit him at a wierd angle and the...

My friends Bronco I have been working on had a short that about drove us crazy that turned out to be the voltage regulator was shorted. He installed the new one and the draw went away. But when I measure his voltage his battery reads about 12.8 volts with key off, then when it starts the volts...

Who has installed both and what's the difficulty of one compared to the other? Centech is $650 and Painless is $950. I read a thread where multiple people said they were able to install the Painless in about 10 hours.
