Alfie623 Posted February 10, 2020 Share Posted February 10, 2020 I've been a member for a few years with limited input or sharing so I thought I'd share my engine build here and then hopefully you'll see my next project in the works in the next few weeks. First I started with this 1986 351 HO. I bought the truck, which was in a pretty bad shape, just to get the engine, knowing that I would be finding a good recipient soon for a swap. It turns out the truck I bought had a lot of good parts and when all said and done I was able to make a few bucks after pulling the engine and I helped some other's out with parts they needed. Here is the engine on the day I brought the truck home. About a year later I found a truck I thought would be a great recipient, a 1983 Bronco found in Northern California. After some negotiating, some wire transfers and arranging transportation, the truck arrived. The truck is in great shape and has a bunch of options that I really wanted including the blank interior, power options and factory fog lights. Here is the old engine, a California emissions ECU controlled, carbureted 302. There is a whole bunch of stuff going on in there and it was a shame to tear apart a California compliant engine from 1983 but it just had to happen. Next up, I got into tearing the old engine down and finding new parts.... Link to comment Share on other sites More sharing options...
Alfie623 Posted February 10, 2020 Author Share Posted February 10, 2020 I stripped the 351 down to the bare naked block and got it ready to send to the machine shop for new parts. The machine shop used Melling components and Lightning specs for the cam. Rather than dictate how I thought the engine should be built, I gave the builder my goals and used his expertise as a 40 year race engine builder to spec the parts. The finished product is still an unknown at this point but I have confidence that I'll be happy. I knew the '86 351 was going to need to breath better so I found some GT40 heads on eBay and bought them. The heads were freshened up as part of the engine work. I also knew that I didn't want to run v-belts so off to the junk yard I went to find the parts and pieces to swap the engine to a serpentine drive. I learned along the way that I would want a Saginaw pump so the quest was to find a late '80's E-series with the correct engine. Link to comment Share on other sites More sharing options...

While the engine was at the machine shop I started acquiring the components I needed to complete the job. My goal is to build an engine that looks like it rolled off the factory line while using parts and pieces that would give me modern day power. You'll see I stayed with the grey color on the block and the accents are stainless, black and yellow. In addition to the Saginaw pump, I've decided to upgrade to a 3G alternator. I've added stainless shorty headers that flow into a 3" stainless exhaust. Here is most of the engine assembled. Link to comment Share on other sites More sharing options...

The ZF5 swap meant I needed pedals, a steering column and to do some fabrication on the driveshafts, the crossmember and the transfer case linkage. Another Bronco was purchased to get a lot of the key components. Here are some pics of the engine. In the next few weeks I plan to reinstall the radiator support and radiator and then fire her up for the first time. Spring is right around the corner and I can't wait to get this truck back on the road. Link to comment Share on other sites More sharing options...

Plus the Sag pump from the other thread. Quite a transformation. Link to comment Share on other sites More sharing options...
Rembrant Posted February 10, 2020 Share Posted February 10, 2020 http://forum.garysgaragemahal.com/file/n50415/IMG_3537.jpeg Excellent thread!! I am a big fan of the 351W engine and I suffer from a severe case of 35W envy! (I have a 302 in my 1984, with the same 3bar GT40 heads that you have). Love all of the pictures. A friend of mine has a 1997 F350 with a 351W roller engine in it that I would love to get and build up like yours. Anyway... Curious what you did for your fuel line there. Are you running a mechanical or electric pump? I see the hose there, but can't see where it goes... Link to comment Share on other sites More sharing options...

Are you running a mechanical or electric pump? I see the hose there, but can't see where it goes... Sorry, I've been meaning to reply to this. Obviously because of the serpentine swap I lost the mechanical fuel pump. Because I'm running an Edelbrock intake and carburetor I decided to go with their fuel pump as well. Because the pump pushes better than it pulls I mounted the pump along the frame rail 1/2 way between the trans and tank where there is already a hose connection or stress relief. I then used new hoses to connect to the stainless lines along the frame. In the engine bay I replace the hose from the hard line to the old fuel pump and ran the new hose directly to the filter you see in the photo. I have yet to start up the pump so the jury is still out but I have faith it'll all work fine. Link to comment Share on other sites More sharing options...
