PMO Carb Manifold Height Options

[defianty]

The engine I have for my six conversion is a 3.0 and was rebuilt and used as a spare for a guy who had an original RS. The engine was used whilst the RS engine was rebuilt. Once thing led to another and he only covered 1,000 miles with the 3.0 before the RS was complete.

The 3.0 had PMOs and I bought them with the engine. When I collected the engine all of the ancillaries were boxed separately and only today, almost a year later, when trying out the carbs for size I thought to myself - "Those look tall!"

Amongst the paper work I can see the 'Tall' manifolds were ordered and a quick google has revealed that these are going to be too tall for a 914, they measure 100mm. To big?

I'd speak to PMO themselves but I'm not sure how they'd be as I'm not the original owner. That and I don't know how to send a fax in 2017!

The good news is that early conversions to 3.0 with Webers and PMO intakes / not talls / fits fine with K&Ns / and the noise at 6 or 7K is something to deal with no matter what the intake system is.

I have no spacers between the heads and intakes and run 3 standard gasket sets between heads intakes and filter bases / no leaks there.

Sidebar: Note the cool flexible perfect fitting carbon fiber "tin" set I made.... Not to worry about flexing and bending when installing or temoving the engine... just pops into place and the rubber from Mark fits perfectly... off topic.... oops
