Figured I'd share the results of my 347 build to give others an idea of what to expect if they use similar parts.
This will be going into my '77 F100 single cab short bed.
Here's a short list of the major components used. I don't have detailed info offhand, so I'll probably come back and update some things when I go through my paperwork.
5.0 roller block from '96 Explorer
Eagle/Scat 347 rotating assembly components. Cast crank/Hypereutectic pistons/H beam rods.
AFR Enforcer heads (cast). No mods, right out of the box. 64cc chambers.
Summit racing Stage 2 intake manifold. No mods.
Melling 24227 cam. 222/232 duration @ .050. .509/.532 lift. 112 lsa
9.8:1 compression
I will be using a Sniper Stealth and Hyperspark ignition when it goes in my truck, but for the dyno run it ran with an 850cfm carb and a no-name MSD-type distributor provided by the shop running the dyno.
I'm kind of doing a '65 Mustang 289 look as far as the paint scheme and the air cleaner go. Just something about the black and gold that I like. Something different from all the blue engines, but still Ford.
That looks great and it has a lot of power in a very small light package.
Thanks!
Long story short, the original plan was a 521. I'm kind of glad I ended up keeping a small block in it though (originally a 302 in the truck) as I like how light the front end feels. I had a 75 F150 2wd lwb with a factory 460 in it before having this truck and it was super front end heavy in comparison to this one. It may even feel slightly more nimble with less iron on the engine now, we'll see.
I don't think that I've ever built one of those from scratch.
I freshened up one that was a 355 one time. The owner used it in a pavement modified circle track car and it did great, It was 65lbs lighter than a 350 Chevy or a 351 Windsor. Also since it was only an 8.200 deck height it worked almost like having the engine sitting about an inch lower in the race car.
Another one I rebuilt was for a local Mustang shop's race car. That one is a 369 built in a Dart block with an AFR head. It made 600 horsepower at 7000rpm on pump gas and they raced it a lot. Now it's in a Maverick that a guy runs auto-crossing and on track days.
It is a neat car. The guy who owns it has called me a few times to get some information on the engine. I think they might be like that to help with heat soak between rounds when doing auto cross. The little engine works great in this application.
It's sitting in the truck now, but its gonna be a while before its up and running. At some point when the weather is nicer I'll order a few parts and finish the install. Curious to see how bad the rear gear is with this engine compared to the factory 302.
