    351W lower head bolt coolant leak

    At my wits end on this engine. Correct me here but 94 plus 351w roller block head bolts do NOT pass into the water jackets? I have a coolant leak that I tracked to the lower head bolt D side # 2 in the torque sequence. This is the only one leaking and you can clearly see coolant coming out as...

    PCV valve sucking oil GT40 intake

    While tearing down my engine to fix the head gasket issue (see thread) http://classicbroncos.com/forums/showthread.php?t=266011 I noticed I was sucking some oil into the intake via the PCV valve in the rear of my GT40 lower intake. My gt40 lower does have the baffle on the bottom. I do not...

    Bubbles in coolant reservoir on my fresh 351W build

    Well I knew my 351W and EFI project went too smoothly. First I bust a Trac-Loc unit (installed a TrueTrac weekend before last) and now I have bubbles in my coolant reservoir. Engine is strong, runs great lots of power. I've got 100-150 miles on the build. Been driving it normal. Driving last...

    TrueTrac install questions Updated

    Well decision made, I'm going to go with a TrueTrac 31 spline. I've read the install instructions and can't find any information on: Bearing size (saw where someone said it needed 102949 bearings vs. stock ? Ring gear bolt size and length? I know my T-loc needed the small heads and 1 1/4...

    Something just went bang/clunk no more rear drive Problem found

    Well was on my way to lunch. Pulled out of my road and went to shift to second and bang/clunk and lost 98% of forward drive. It would still go forward but like at 2mph and any little hill would stop all forward momentum. Pulled to a stop and while in gear, she rolled backwards. Nothing...

    Grafted rear quarters vendor had them now they don't?

    So does anyone know of a source for these? One vendor was selling them and now they no longer list them. Was looking to do this as my next project. My fenders are cut and I want the original fronts and grafted rears. Anyone doing their own? Using maybe 78-79 rear's or maybe F100's? Tim

    351W and EFI conversion project a success

    Fired up the 351W last night and let it idle for a bit. No leaks no drips no errors that I could find. It's been a long project from start to finish but she's done but for buttoning up a few small things. My project started Dec 25th 2014 when I bought the 96 donor van for the 351w. Parted...

    Low Pressure external EFI pump recomendations

    What pump is everyone running? ACDelco EP247 or something different? Been around and around on if I need LP pump and accumulator and had planed on NOT running them but now I'm kicking the idea around. I know some are LOUD as all get out. I would like to get one that's not going to be heard...

    EFI inline fuel filter questions

    It appears that most off the shelf inline metal filters are 5/15th inlet and outlet. I found one Fram that has a 3/8th inlet but 5/15th outlet. I'm plumbing my system with 3/8th braided and hard lines and I'm worried that running a filter with 5/16th inlet and outlet will cause pressure...

    74 ignition switch EFI wiring help

    Trying to button up my 351W and EFI conversion and think my ignition switch is faulty. Heck, maybe not even the correct one for 74 I did some searching and looking at the vendors sites and I seem to have more wires to my switch than what I can find. Not surprising as my wiring is hacked all...

    Trying to figure out the integration into the Bronco harness. I've already taken off the stock regulator. My 74 has a plug on the firewall with 3 wires, black, black and green/yellow/red (faded badly) Guessing the green/yellow/red connects to the green/red from the 3G Alt. The 2 black wires...

    EFI air filter which one?

    Got some questions on what everyone is running for air filters with their EFI setup. I noticed via searching that several different shapes are being used and it appears different makes as well. What size is everyone running? I was looking at an oil less AEM 21-204DK or the 21-2049DK. Will a...

    O2 sensor wiring help

    So I've taken my 96 van Speed Density wiring harness and have converted it to Mass Air. I have everything wired up but the O2 sensors and I think I'm Jedi mind tricking myself. So I'm using a 95 mustang GT ECU (because it works well with the wiring and remote TFI from the van) and the O2...

    OK, so I'm finishing up the loose ends on my 351W conversion and have the 02 F250 7.3PSD Lower Radiator hose in hand and I just don't see how in the word it's going to fit. I have the correct hose (there are 2 listed and I have the one for the straight outlet not the curved) but I can't...

    EFI Fuel system help...tank, pump, etc.

    Getting closer and closer to the finish line on my 351W conversion and have started thinking about the fuel system. Seems to be 2 ways to go 1. External pump with accumulator 2. Internal pump. What's the best and why? I'm hoping to run a tank from Aero as I can get a custom 18-20 gal tank...
