[@darinwilton9122]

i did a similar upgrade on my 81. had a 302 with an 86 efi bank fired system like this one had. i put in a weiand stealth intake, holley sniper kit, billet speed fx hei distributor, and also full length hooker headers with thrush welded mufflers turned down before the rear end. perfect old-school sound in my opinion. and my truck used to have the crappy aod trans and i put in a 5-speed from a 92 flareside. the 302 was from a 94 mustang so it has the roller cam in it. talk about waking up a truck. been running great for the last 5 years while only having to replace the o2 sensor after the first 11 months. anyway, love the videos and the work Mook does on vehicles. oh, almost forgot, get rid of the oem oil pump shaft and go with an ARP pump shaft to save yourself the future trouble of twisting the oem shaft in half like i did from having a heavy foot lmao keep them videos coming :)

[@AutoCrete]

GOOD EPISODE! I learned quite a bit about installing aftermarket fuel injection from this video. In the mid 80's fuel injection was near magic and Edelbrock made one that gave Chev 350's a really solid kick in the pants. Again, back then FI was considered "near magic". Damn I'm a fossil!

[@taylorhelm7146]

So from working on these 2G alternators myself and digging through forums, I'll give yall some helpful info. If the battery is dead and you try jump the car, its known to fry the 2Gs. It's best to recharge the battery, not jump. Its often typical to change both the battery and alternator in THIS type of setup. They also only go as high as like 110 amps depending on the model, usually around 75 amps for most. That's why people generally recommend installing a 3G and upgrading the gauge of wire for the charging system circuit.

[@Axle..]

I would highly recommend upgrading your alternator to the 3G version, the 2G are known to not charge very well. All you need is put some 3G plugs on your existing alternator wire and grind off a bit of the alternator bracket as the 3G one is a bit bigger, but it will bolt up once that is done. I did it myself and have had no troubles with it. It also opens up other upgrades like putting in a new radio or any other higher power draw upgrades you might think to do.

[@Maples01]

The 2G is known to start fires, in fact, the replacement wiring harness warns it can catch on fire so its best to get them off ASAP, I put a 3G on a 73 Econoline, learned they must use a serpentine belt tho, it will burn up a V-belt, must run at least 2 v-belts when using on a vintage engine.

[@brandonjohnston7746]

@@Maples01 bingo 💯

[@Maples01]

@@brandonjohnston7746 I have a guy who builds mine, while you can find 200 amp 3G alternators on ebay, you will not find the guts to build one, they have been discontinued, which has me skeptical of what is sold online as a 200 amp 3G, I believe they just swap the pulley to spin them faster. I can tell you the durability of the 3G is like no other, my wheelchair cable, 2 gauge, fell on my exhaust, welding itself to it, boiled over my battery putting the alternator in over charge, I don't know how long it was like that, did not damage the alternator, won me over. I was going to put one on my 89 E150, but my shop guy told me it is not a 2G as it should be, its a special order large case found on RV's and Ambulances.

I bought Hooker ceramic coated headers for my 95 351 project truck, would not clear the frame on passenger side, couldn't tighten them at all. Summit support was great, took them back and I tried Headman, those slipped right in from below without even needing to remove the starter. Sadly they didn't have a ceramic coated version. Cool project you have going

Alternators on mine as well. I just changed mine but had a tester that tested the battery as well and it also had a dead cell even though the new alternator charged the battery, the starting, cranking was just not right so had to replace the battery. The newer alternator i got has a permanent alternator wire since they were running into corrosion with that connector. Had to splice but its solid now.

Superduty bolt kit for the bed. Everything becomes accessible from above. Dorman 924311. You will have no regrets and they will work at least back to the 1973 model year with a slight modification to the width of the frame on the rear bolt only.

[@bigmizzymike]

Oh look it's a Mook. Yay!

[@Billhatestheinternet]

A lot of guys used to use RTV on top of the cork valve cover gasket (so it would adhere to the cover), and use grease on the side of the gasket facing the head (axle grease will seal in motor oil). This was to facilitate more convenient (and less messy) valve adjustments, as well as not needing to replace the gasket every single time.

Regarding the factory bed mount bolts, one can use Torx head bolts and U-nuts in place of the original style shoulder bolts & nuts that are so prone to becoming one piece. I have done this with a couple of OBS truck beds and sourced my bolts & nuts from late '90s Rangers. Remember to also use a proper anti-seize compound when reinstalling the bed.

Kinda funny, I swear the only thing that works on my 1993 F150 IS the EFI system! AC? Nope... Heat? Sure, if you want the fan on full blast. Power windows? Eh, kinda? The drivers side window seems to want to fall into the door, rear gas tank leaks, front one is plastic so it should last another 30 years before turning to dust, and don't get me started on the rest of the truck, especially the oil gauge, which is just having a moment and flailing wildly around, it works when you're cruising but at idle the oil pressure is "AAAAAAAHHHHH!".

We had a 98 v-6 ford fuel injected car. Almost all the plug ins under the hood would crack and break when you went to unplug them, so frustrating. I removed the intake to cleanup and replace injectors then ended up just reassembling and driving it down to use as a trade in. The heat buildup under the hood must have weakened the plastic connectors and the snap locks would break.

I've got a 90 F150 4x4 extra cab and had problem with fuel it ended up being the switch on the dash. I had to test it a lot cause it wouldn't do it every time and that's with the switch being out and on my bench. Then I couldn't find the right replace switch with the right face so I had to take apart the old and the new switches and modify to fit and that took care of it. I would have like to have seen all of the removing of the fuel lines and everything you did. Sorry for this being long. You done the right thing by going with the long tube headers I'm putting on the shorty "bolt in" headers and one side is not the same as the other right is smaller and mine was a true dual exhaust now I'm stuck until move funds are found for new exhaust it could use it but it still had some life left but the new shorty's still look good under the hood 👍

If I remember correctly a 4.0 90's Ford Explorer belt is the correct length for the air pump delete. (I had a 89 myself) In those years there is a aluminum piece in the column that actuates the ignition switch that cracks and breaks causing them not to crank as it can't push the switch hard enough. Tilting the column up might temporarily help.

I know I'm late. Mook, there's a really easy way to keep the twin tanks and keep modern EFI. Use a low pressure carbie pump in the second tank (or an external clicky clack) Then run a double T or pair of T barbs in the vent or the primary tank. Then you can pump the fuel from the second tank into the first, without needing one of the un reliable tank selectors.

[@dispatch444]

Makes me miss my Ferd straight six 4 speed manual. Mine was the two tank flavor, believe it or not I had absolutely no issues with any part of the fuel system.
