All right, due to its popularity, here's a pic of the 427 as it is right now in CAD:

Sooo Nice!!!
You have even put in the correct dry sump setup, this one I'm hopefully going to buy at least two of.
The HRM engine is also a small block for Mk I so this will probably be the only FE conversion engine for the Mk II and it would work for the Mk IV too...the Mk IV had dual Holley 4160 carbs tho'.

Did anyone say Mk IV dual Holleys? Might not need that aircleaner though ;)

The Mk IV  dual carburetor setup was a one year only and they didn't have that style air cleaner,  if they had air cleaners it was small round ones, one on each carburetor.
Ford used the Holley 4160 style carburetors mounted backwards, they will not fit otherwise as the float bowl will interfere with the distributor if mounted the other way, you have drawn in the 4150 style carburetors in this picture and they will not physically fit on a Ford FE dual carb intake manifold as they are too large, the 4160 is smaller and has only one metering block, the 4150 has two metering blocks and that and the upside down V shape where the fuel goes in makes them too long for this application.

Here is the dual carb setup on the 1967 LeMans Winner, car No 1.

The Mk IV had the carburetors mounted in air boxes and here are a couple of styles used, here is the No 4 car.

Here is car No 1 again now with the air box mounted.

Hello Håkan, you've got a sharp eye!  I just used the 4150 Holleys just for reference in my model, I have already drawn the 4160s too. What do you say, is a mid-riser intake correct for a Mk2 or Mk4 setup?

And you've got some great pics there, do you happen to have any length measurement of the Karkraft gearbox? I've already printed it in 1/8, and it looks so huge...

I'm not 100% sure but I think the Mk II and Mk IV had medium riser heads and intake manifolds, the high riser came in 1963 but was mostly used 64-65 in NASCAR and Drag Racing, I don't know if the high riser was used in anything else.
The Mk II was raced at LeMans in 1965 but none of the cars finished the race...and we all know the story for 1966.;)

The first picture is not J5, notice the triple stripes, J5 was dual stripes. The Holman-Moody cars has triple stripes. That is chassis J7

I believe the alternator was mounted near the crank shaft pulley like this.

Hello JC,

you're absolutely right!  The pic shows my WIP engine with stock auxiliaries, I'll have to correct the alternator position on the model. I wonder wether I'll have to draw the setup or if it can be done on the printed parts.

And of course the single Holley isn't correct either, but I've drawn the correct one already.

Yes you are absolutely right, I just looked at the color.
I looked at my files and the first picture is as you say car No 3, Chassis J7 driven by Andretti/Bianchi wich did not finish the 67 LeMans race.

As Mad Mike says, the single carburetor version for the Mk II should have this early style of the 4150 with the "LeMans" float bowls wich also can be seen in his engine picture above.

While you sort out the correct carburetor setups, you're all sorting it beautifully. BTW. I do believe that the dual 4 barrel setup was a tunnel port 427 and not an earlier mid rider or high riser. I could be wrong, hard to tell on the 1:1 pictures with all the plumbing in place.

Yes it's hard to see but it looks like they could have had both Mid-Riser and Tunnel Port, I have seen pictures of both setups in the Mk IV.
There is not that many Mk IV kits out there, only the IMC/Testors and MPC kits wich have engines, so that engine option may not be as desirable as the one for the Fujimi Mk II curbside kits, they used the dual carb setup in the Mk IIB for 1967 tho'.

55 Euros = $67.86 at the current exchange rate.  Looking at $80 with shipping I would guess.

It's a bit cheaper if you have an account. I think when I looked at it for me, logged in, it was 46.20ish Euro + 7.80ish shipping, came to 54 Euro....exchanged into Canadian was about $81. Expensive, yes. Super detailed and ultra cool looking yes, still sitting on the fence tho, I knew it would be pricey, but $80 just for the motor is steep. If I was a world class builder and knew putting it in a build would help me win a contest, sure, but alas, I'm not that guy, so $80 to sit in a kit that will be buried ontop of my workbench once completed??? Not sure yet, but I love GT40's so I'm likely to order one.
