Dimensions - early Valiant

Why not tell us what you plan to install? If someone's done it, they can give you some pointers.

No worries. I'm in Australia and interested in swapping in a a standard Ford Turbo Barra engine. These things make enough grunt out of the factory to get a heavy Falcon down a race track on regular radials in 12.6 secs. Early Valiant is 1000lbs lighter but my not have the height in the engine bay.
