Cobra 427

[afxracing]

Revell/Monogram makes and excellent 427 Cobra kit but it is 1/24 scale. I have a few built AMT 1/25 Cobra is in my collection and the Monogram kit looks out place next to them. So I want to build a 1/25 scale Big Block (BB) Cobra.

Comparison of scale. The AMT kit is on the right, The Sunny 427 kit is center and the Revell/Monogram is left.



Kit I am starting with.

The BB Cobra ran coil spring suspension. The small block (SB) car ran leaf spring suspension. The Sunny kit is based on the AMT kit which is a SB car. Although the Sunny kit includes most of the body mods for the BB car it includes and incorrect chassis and engine.

Here I have modified the Monogram suspension to fit the Sunny chassis. The stock AMT chassis is shown for comparison.

You will note I haven't modified the rear suspension. The rear suspension is almost complete obscured on the finished model. I may added the coil-overs (if I have room) to make the rear suspension more accurate.

Why don't you buy the Shelby Collectibles Cobra 289. It is pretty good and can be torn apart just like a plastic kit and it is supposed to be 1/24th scale. A lot more versions are available for the Cobra in 1/24th scale than 1/25th.

Yes there is a lot more Cobra choices in 1/24 scale. But a 1/24 scale 427 overwhelms my other 1/25 scale 289 Cobras. Its a lot of extra work but I think its worth it.

Thanks Paolo. The FIA Cobras maintained the original "D" shaped nose while the 427 cars have a larger oval shape and the oil cooler opening underneath. The 427 engine required a lot more cooling than the 289.

The gray car on the right is the AMT kit, a 289 Cobra. This kit:



This is what the nose of the AMT kit looks like. Picture is from another of my Cobra projects.



The nose of the Sunny 427 kit looks like this:

Using the 1/25 scale Revell Parts Pack 427 engine for the block, heads & transmission and some other bits. The headers, intake manifold and carbs come from the 1/24 scale Monogram 427 modified to fit.
