Move the pivot point back, onto the main body. That will increase the clearance while the hood is opened.

We have also found that when using original GT40 cast wheels, 11.75" is the maximum rotor diameter in the front.

What brand of replica do you have?

I've got a very crude DWG 3D model of a 302 that includes the engine mount bosses (and some other stuff). Some of the surfaces are missing, but that shouldn't effect what you need. E-mail me at [email protected]

This is probably due to gyroscopic reaction. Not much you can do to change it except reduce the rotational inertia with lighter wheels and tires.

A copy of the ERA system. It even uses the same BMW slave. However, we put the bleeder at the top.

The temperature variation from side to side is way too much. Measuring the temperature of each pipe near the head will isolate any cylinder that's weak. Something's not right, either mixture-wise or even no ignition at all.

If it has a bolt-on steering arm, a custom (shorter) one might be the simplest path.

If you are using the trans in its original (Ford GT) orientation, we recommend these modifications: http://www.erareplicas.com/gtman/transaxle/zf-mods.pdf

It shows OK for me in Foxit Reader. (Their viewer is in Beta, but it works.)

The biggest weakness (torsionally) that I see is through the area near the front of the side "pods". The structure needs something to tie the two pods together like a large transverse box well connected to the side structures.

Note that all those engines really have the same cylinders firing 90 degrees apart, just in a different sequence. If the tube lengths from the heads to the collector are equal, the same layout into the collector will work, no matter which engine.

Without some indication of what's happening in the vertical plane, it's impossible to properly evaluate either design.

You are assuming a single 5/8" master cylinder to operate both front and rear brakes. Typically, there are two masters on a balance bar system. The balance bar geometry decreases the force into each master cylinder by roughly 50%.
