The McLaren that AMT designed and passed off for many 1974-75 McLaren M16s was actually based on a 1973 McLaren Indycar and has many inaccuracies. One glaring error was the straight exhaust that was not used on the 74-76 McLarens. The gearbox doesn't look like any gearbox used in any car, ever. If possible we recommend using a Bill Jorgensen kit or conversion kit for even greater accuracy. This kit is recommended for advanced modelers who are willing to modify the kit for better fit and accuracy.

Offenhauser engine and gearbox

1/25 scale resin

Highly detailed replacement Offenhauser engine and gearbox for the AMT kits. This particular configuration is designed for use in the McLaren kits - the difference from the Eagle configuration is an extra spacer between the engine and gearbox. Will probably work as-is with an Eagle, but to be correct you can trim out 1/10" from the spacer. You can use the AMT exhaust/intakes, aftermarket parts prodcued by Bill Jorgensen or Lance Sellers or you can use our own highly-accurate and detailed parts, which are available as 3d prints through our Shapeways store.

Each kit includes one block/gearbox, one mounting plate and one left side burst plate.

Our 3d printed accesories for this product can be found at our Shapeways Store Offenhauser Parts section.
