wow. Mad skillz, you has them.
Absolutely amazing.
I just hope we can keep up with you long enough to feel the fury!

That should be pretty easy. drivers will be instructed to take it easy until everyone has at least had one turn on it 
sorry, no pictures of tonight's progress. the damn server i host the pictures on appears to be down again 
anyways, I spent some time preparing all the components for the oil tank that is going in the front trunk. and i also made some exhaust baffles using perforated steel.
i also added a wideband O2 sensor to the #1 cylinder. i needed something to help tune it and i figured there's no reason to not just mount it permanently. this should mean significantly better AFR targets.

While I can't figure out why our simple 5.0L FI engine is sputtering at high rpm you're over here tuning by one cylinder at a time. You're my new hero (move over Speedy!)!
(p.s., know yer 5.0?)

I've spent a bunch of time with those ford 5.0L motors doing offroading. the ford setup is pretty hard to screw up. drop me an e-mail if you want a copy of the cut down schematic i normally use to wire those engines up.
and to clarify, i'm not tuning one cylinder at a time. i'm tunning one cylinder conservatively and letting the others land where they will (they should be close)
That is just incredible! You truly are the Charlie Daniels of the torque-wrench Marc, I can't wait to see it in person.
Ha! Who knew there were other Sammy Kershaw fans outside of the South?

It took me a bit to get the reference. thanks guys
this first fire video is spreading like wildfire. I've never had a video get over 600views in less than a day.
Off to work for now. the plan for tonight is to finish oil tank prep so i can hand it off to my buddy that makes me look like a i'm just flinging bird shit at metal when it comes to welding. i also plan on getting the exhaust finished up with the baffles so i can try firing again on Thursday and set a few basic operating parameters on the engine.
also, for those that are curious. i ended up setting the timing at 0 degrees for starting because i was really concerned about it firing backwards with the super slow cranking. given how easily it started i'm just going to leave that setting right there.
Make it to where it has a really long stumble on start-up and then fires off with a huge bang and tons of smokes pours out the exhaust like the WWII B-17 and F4U videos usually show. That would be smooth.

port injected EFI really solves quite a bit of that especially since i'm using super fine atomizing fuel injectors.
starts will become a bit more dramatic once the lower cylinders fill with oil. expect lots of smoke and harder starts.
that is awesome. well done.

F4U...drool.

Ok, now I really want one of those wasp engines!
There's one for sale:

Ear delicious...

that really is ear candy. the kinner dosen't sound that different at idle. but it really lost most of it's startup "personality" when i converted it to EFI.
I Love this project!!!
the leverage on that shaft has me worried also. but there's no way to know for sure. the size of the sprocket will help it.
You could add a free riding bearing plate to keep the chain tensioned. 2 surface mount bearings collared to stub shafts protruding from each sprocket mount and a slide assembly to adjust. Similar to the Harley Davidson big twins use with belt drives.
Somewhat like this:
It would also make a good place to mount your chain guard.

something like that has occurred to me as a possibility that i could implement, but unless i find some extra time out of thin air, it won't be happening. plus, i need a place for the cooling fan and i'm running out of room between the firewall and the end of the shaft.
I get you. If you were near Dallas I'd offer to come help. After building the Dauphine I have a decent idea of just how much work is involved in the last 10% of the project...

that was an awesome car.
thankfully I haven't been cutting corners as i go so i don't have a big mess to clean up.
the cage is scheduled for this weekend and the rest of the team is coming to help me. I need human welding clamps (way more configurable than any metal clamp, burns be damned!) and someone to row the slave boat (manual tube bender)
other than that, it should be pretty close. i suspect i'll still be tuning on Friday at the track.

another day in the shop.
welded up all the exhaust pipes and applied some high temp paint. 
(the bottom ones are there too, i just did not highlight the tips
i decided to add a wideband sensor to cyl #1:
added some baffles in the pipes though it was too late in the evening to test the noise level.
also finished all the machining for the oil tank. (excuse these pictures, they were taken from my cell phone in the shop)
the ports are: Fill, vent, in and out. the vent will be routed to the crankcase so i don't have to worry about the tank burping. the capacity is just a hair under 5 gallons, I'll probably fill it to about 4 or 4.5 gal. with the stuff in the motor and in the lines we're looking at about 5 gal total system capacity.
and to show off my buddy's welding:
hopefully he'll have time to weld in all the bungs tomorrow.

Wow.. nice fab work...
