Shelby Cobra 427 '66 Sebring - 4/21 Finished

Recommended Posts

Since I'm in a Cobra mood and I had to surrender my Dragonsake to the resin caster I thought I would scratch that itch by taking on a 1/25 scale Cobra 427.  Revellogram offers a very nice 427 but it is 1/24 scale.  Since I have a few 1/25 scale 289 Cobras in my collection I really want a 1/25 scale 427 to keep everything in scale.  Here the scale difference is obvious.  The gray car on the right is the AMT Cobra, middle car is the Sunny 427 and the red car on the left is the Monogram kit.

The Sunny/Minicraft kit doesn't get much love and while some of the criticism is deserved I think (hope) I can build a respectable big block Cobra. 

Personally I like the Sunny body  Here it is a compared to the Monogram.

I don't intend on correcting every discrepancy in an effort to create the ultimate 1/25 scale 427 but I do want it to look the part to any knowledgeable Cobra fan.

The Sunny kit is based on the AMT kit and this is where the problems begin. The AMT kit (which I also like very much) is a small block (260/289) chassis and as such used the leaf spring suspension.  The big block (427) car ran the updated coil spring suspension.  So the first order of business is the attempt the suspension conversion. I have modified the front suspension components from an old glue bomb Monogram.  Here compared to a stock AMT chassis you can see the differences.  Note my modified suspension is still missing the coil over shocks and the steering tie-rods.

You know I will be watching. I am sure you will do a fine job. Very interested in the outcome.

Best of luck JC, that's not an easy conversion. Even building the Minicraft out of box is difficult enough, with the front metal axle. I nearly threw it out of the window several times.

I'm sure it'll be gorgeous when you're finished though:D

Thanks Ray & Shay.  I know there are some passionate Cobra fans on this forum, including myself and I won't meet everyone's expectation on this build I am sure. Not trying to set the bar just raise it a bit.

Looking at the first pic with the 3 bodies, the difference in the rear of the bodies between the AMT and the other 2, is that because of small block versus big block?

It is Robert.  The big block car had both front and the rear fenders widened to fit larger tires.  In fact they increased the width of the whole car to accomidate the bigger engine. They also beefed up the chassis by increasing the main fame tubes from 3" OD on the SB chassis to 4"OD on the BB chassis.

Towards the end of the Shelby contract  AC cars did a short run of SB engined cars using the BB coils spring chassis.  They called their car an AC289.

Thanks Len & Carl. 

I plan to make the front suspension fairly accurate since it is visible in the engine bay and from underneath.   I am taking a bit of a short cut with the rear suspension using the leaf springs in lieu of fabricating the upper A arms which would be almost fully obscured on the completed build.  I hope I have room to add the coil overs at the rear suspension. Some reference photos for comparison.

Yea Mike the Cougar II was built on a Cobra leaf spring chassis CSX2008 and the IMC kit is indeed based on the AMT chassis.  Here is a picture of the Cougar II chassis from Bill Geary's excellent build of that kit.

Glad to see this in the works. I'm deprived with having no Cobra kit and have wanted to see one going together. The kit bashing makes it even better!  :)

AC had to modify the foot boxes to make room for the 427.  Of course the Sunny kit doesn't includes these mods.  The interior on the right is the kit part, the one on the left I have modified.

I now have room (I hope) to squeeze in the Revel Parts Pack 427.

Fabricated some simple shocks.  I will add the coil springs before they are permanently installed.

Thanks Carl & Dave.

Started modifying the Monogram parts to fit the Revell engine block.

DSCN2981

Plan on using the Monogram hood as well.  A quick test fit shows everything should fit under the hood.

More engine fitting.

Headers even line up with the fender opening - I love it when that happens:)
