Project 1977 F100 - New radiator + electric fan!

Hi guys,

Thanks for the kind words, this truck is much easyer to work on than any of my other cars so its nice to be able to do custom stuff like this

havnt really done much since last update, too busy on other things.

I filled up again today though, most of this tank was city driving in horrible rainy cold weather and the engine was missfiring a bit for most of the tank so even with me introducing some hypermiling techniques (downhill coasts wherever possible - engine on, and pulse and glide at highway speeds - also engine on) i only managed just over half a MPG increase on the last tank (7.58mpg over the previous 6.98mpg)

still moving in the right direction though so i cant complain, and now its running much better so the next tank should see a bigger improvement.

thanks for lookin

Hi guys,

i did some more work on my dash yesterday, got the guage cluster all glued up, just needs to be trimmed now and i need to buy the rest of the guages.


the tiny holes will be for turn signal and high beam lights and along the bottom will be oil pressure, vacuum, and water temp guages.

i also got my reversing lights in the other day, i think i may have gone slightly overboard but i definitely wont have trouble seeing behind me at night anymore.




Thanks for looking

The back up lights are something I rarely, if ever, look to for efficiency changes. How often are they ever really lit up?!

Unless you're looking to shave every ounce, and even then, they could be literally the last thing on the list. They serve a valid purpose, no reason to pick on them.

I didn't add the back up lights for energy saving, my truck didn't come with any from factory so I couldn't see behind me when reversing before, Ive added these on a switch so now i can see behind me, they are brighter than i expected when i bought them though lol!

I ordered a water temp and oil pressure guage today to complete my new guage cluster, and also cut all of the factory connectors out of one of my old cars that is getting scrapped so i can service parts of the dash easily without cutting any wires (each section just unclips now)


Ive also fitted a Vacuum gauge now too, and continued wiring everything up to the factory style connectors, to pull my instrument cluster out now i just need to undo 1 plug, the speedo cable and the vac line instead of undoing 13 wires as well


The oil press and water temp gauges i ordered match the vac gauge too

Thanks for looking

Hi guys,

The oil pressure and water temp guages arrived today


I'm also nearly at refill time again so now that it has been running properly the last tank I can finally get a baseline for some mods

first thing I'm looking at is either diff or gearbox as I'm sick of watching all my fuel disappear doing >4000rpm on the motorway

Thanks for looking

Hi guys,

Refilled with LPG today, had a nasty surprise waiting for me at the pump... a 0.8mpg drop since the last tank

I'm not sure why this has happened, the weather has been similar to the last tank and so has my driving style and where I've been driving, the only thing i can think of that's changed has been the engine was misfiring and generally running bad last tank but this tank it was running well, this doesn't make sense to me...

can anyone else think why my mileage may have dropped so badly?

[Flakbadger]

Wow that's weird, I'm not exactly sure why it's doing so crappy 'cause I'm not the most experienced mechanic in the world... But I wonder if your carb is adjusted right? Being that this runs on LPG, is the fuel line under a bit of pressure? (EDIT: IE is it under MORE pressure than it was originally designed to run) It could be possible that the fuel line is leaking somewhere, especially if it's older.
Hopefully someone else smarter than me reads this and can give you better ideas. Best of luck.

[bobo333]

The LPG system has a separate tank/lines/carby, it doesn't use any of the usual gasoline parts, i haven't noticed any leaks (LPG has quite a strong smell), not sure if the carb is adjusted right i might have to go to one of my friends who is a mechanic and get him to look at it.

hey guys

not having any form of instant MPG feedback makes finding the optimum driving technique really difficult... this tank im trying DWL instead of pulse and glide at lower speeds as i dont think my glides were long enough to be useful over the last couple of tanks

ive nearly finished my dash now
speakers on each end:




amp inside where the glovebox used to be:


sub box between the seats:


painted (for now till i get around to trimming it all)




and LEDs installed above the speedo so i can see how fast im going:

Hi guys,

had another fill up today, mostly city driving again but this time i tried to use more DWL, DWB and keeping the vacuum up as much as possible instead of P+G, looks like this car much prefers this style of driving as it gave me 7.4mpg over the previous tanks 6.8mpg, although this tank had a bit warmer weather than the last couple and much less rain...

its really annoying having such long intervals between mileage calculations...

in other news i finally took off the mud flaps yesterday:


im still looking for an appropriate ratio diff or gearbox replacement and going through ideas for a aero bed cover and undertray, any suggestions dont hesitate to post on here
