Modified Duratec Intake Manifold
By brad on May 7, 2009 | In Photos

Manifold was cut apart, throttle body moved behind head and connected with 2.75" hose (with metal spring liner to avoid collapse under vacuum).

Similar shot

Looking from other side, throttle body w/ hose in the background. Note that TPS is inverted from normal app to keep away from heat shield and exh manifold - just disassemble and flip 180 degrees.
EGR port in manifold was eliminated in this app - no emissions requirement for '73 car. Port plugged, EGR valve replaced with blanking plate.

I have a few questions, which you might be about to answer, before commiting to another engine change:
Does the sump fit between the chassis rails?
Will you need to bulge the bonnet?
Does the front pulley fit ok behind the crossmember supporting the steering rack?
What bellhousing are you using?
I could go on for several pages I think. Any help greatly appreciated.

The sump fits fine between the rails, but yes I'll need to bulge the bonnet. The DOHC is very tall.
The pulley fits OK, although I have notched the crossmember to facilitate ease of installation/removal.
The bellhousing is a custom one made by a guy who runs "Quad4Rods". It bolted up perfectly. (www.quad4rods.com)
So, I'll try and stay connected through the winter and look forward to future posts.

The photo of the front of the engine bay is very helpful. What determined the height of the engine? The gearbox or the bottom pulley fitting above the front cross member? What gearbox are you using? I’m keen not to have a bonnet bulge, if I removed the crossmember and put the strength back somewhere else do you think I could get the engine low enough, dry sump obviously.
My car is LHD, looks like things might be quite tight with the exhaust and steering column.
Keep us up to date on the progress.
PS. Those wheels are huge.
