My son puts one of those legs in his front window every Christmas,
so yes, I'm familiar.

Funny, that thing was delivered to him in the same box as the movie....

I trimmed .125 off of the end of the coil. Also shortened the top of the plug tubes by .200.

The threaded spacers to mount the coils are .400 thick.

Very cool!

With the coil on plug setup do you use a distributor? I can't see what's under the distributor hold-down.

Thanks. No distributor, just a cam sensor that Andy makes.

thank you for the info ! bow
i'm not sure i can ever use it, but it's nice to know a relatively easy coil-on-plug setup can be installed on a hemi and look good as well. up

I moved the engine to a rolling table, installed clutch and flywheel. Did a cranking compression test on one cylinder just out of curiosity.

Also didn't like the look of the vacuum pump relief valve so put it inside a breather.

Also Brian Smith designed some header flanges for me but was unable to find someone to machine them for less than $1400 shocked Not really sure where to go with that so may just bail on my header building idea and order some TTi's.

That EFI/COP setup is so beautiful this thread should be put in the tech archives for later reference.

Hasn't been much interest in maintaining the tech archives....And once it is archived, nobody can reply to it.

I would suggest, at whatever point it's comfortable to move, that it should be moved to the Member's project area instead.
It's over here
Supposedly pictures will be saved as long as the servers keep running, and the thread can be replied to continuously.

Great thread ! up

As an aside, I believe the OEM AUDI/VW coil packs are a direct fit and don't require trimming like the Coyote coils do. It would perhaps depend on whether you are using Indy or Stage V heads as I believe the Indy plug tubes are taller.

I will be going down the EFI path at a later time on my 572 and am collecting parts atm.

The breather cap / relief valve is positively inspired.
The whole project is pretty awesome , but those little touches are what shoves a project to the front of the line for me.
Very nice !

Well thank you, much appreciated.

I originally made a bracket (that I didn't take photos of) to brace the top alternator mount to the water pump..... Then noticed after tensioning the vacuum pump it was easily flexing on it's studs if I pulled on the belt.

Hmmm, don't like that.

Toss alternator support bracket in the trash and start over to include vacuum pump. Very solid now.

Finally caved and ordered some TTi headers. Very impressed by the construction and fitment. Thick flat flanges, not just a ground down weld beat at each port.

I welded o2 bungs in them and had them coated locally. Color is called "titanium" and they say rated for 1800deg. Installed with my favorite sealant, Toyota FIPG and no gaskets. Also used Zircoflex ceramic heat shield around the starter.

Some more photos. Everything fits well so far. Also wired up an output to a relay to use the hood turn signal lights as a shift light as well smile
