Ferrari 360 engine and transaxle

[scott]

Rob, you may already know this but on the early 360 engines there were 2 critical changes necessary:
1. Replacement of the cam variator shaft – critical owing to dire consequences of failure (engine is toast).
2. Starter ring gear (3-bolt to 6-bolt).

the lift can be anything till the spring binds, then the spring is changed, and again lift can be increased, or to the point the buckets start to fail..... etc etc etc etc,
rule of thumb is that there's no point in running more lift than 1/4th of the valve diameter, hence the nice thing about 3 intake valves: smaller valves means less lift required, + possible smaller and lighter single valve, with less engergy required to opperate, All this adds to higher rpm capabilities which equals more power for the torque produced and that is where that intake port comes into play....

like pointed out before. it's an engineering marvel.

good going Mesa and Thanks for sharing, quetsion though

Has this engine got the cam fazing only in the timing of it, or does it also have varriable lift?
I understand that ferrari has use some sort of elliptical lop desing and that the complete profile-part of the cam touching the bucket could shift left to right changing the complet profile of it for a givven RPM, if so could you show us that? I've only read it in a mag once or twice but cannot find any pictures of it anywhere. would be nice!

Each exhaust camshaft has a timing variator which, by the way, is controlled by the Motronic ECU. Something to think about when changing electronics.

It does nothing more than retard the exhaust (only) timing by 10 degrees under certain conditions (like high rpm).

Scott,
The Pectel unit does have the ability to control VCT so it should be able to handle the job. Thanks for the heads up on the updates for the engine, fortunately I was already aware of the need.

Thomas,
As Scott said there is no cam profile altering technology in this engine, only timing.

It's sounds like you know what you are doing so you should have some fun! My 360 had a Tubi exhaust and no cats, and there is a nice tunnel up the canyon from me. I loved the sound of the flat plane crank engine at 8500 rpm in the tunnel, sounded like an F1 car.

follow the link and you will see a V12 build from start to finish. Truly a work of art.http://www.autoclips.net/video/play/4713.

As my SLC nears delivery I need to create some room, therefore I’m getting off the fence and officially offering my Ferrari powertrain for sale.

360 Modena, five valves per cylinder, titanium valves and rods, cable shift 6 speed. 17,500 USD for everything I have.

Engine, clutch, transaxle, approximately 18,000 miles. Heads and pan pulled for inspection, Ferrari service and parts manual CD included with sale.

No induction system (I planned to fabricate my own ITB manifold), no generator or A/C pump.

Main needed items – cam belts, cam belt covers, cam belt tensioners, one cam variator, external oil return pipe, full gasket set, 6 bolt starter ring gear, starter.
