Alfa V6 sizing and stuff...
akumabito - 22/1/08 at 12:18 AM

I found one of Johnmor's old posts, stating the 3.0 V6 12V engine is 640mm tall, 540mm wide and 710mm long. A silly question maybe, but can the engine be made shorter at all? Johnmor said the length was measured over the distributor. Any way to relocate this? Any other tricks to shorten the engine a few cms? I'm looking for a way to gain about 15cm.

(yea, still drawing on napkins. Not actually building anything.. )

Assuming the v6 is even fire, replace the dizzy with a ford edis system. Requires a 36 -1 trigger wheel and a sytem to tell the advance required.

10 btdc is the defualt timing.

If you need save 150mm you may be
pushing it.

If you used a dizzy from an Alfa 75 it mounts on the front of the engine and may save around 80mm or you could use the coil packs from an alfa 155 2.5 v6.

At the other end of the engine is the thermostat housing that protrudes through the cam belt area . The Alfa 155 used somehting slightly less protruding so may save anther 50mm.
The plenum chamber sticks out a bit too

The block itself is only around 520mm long so there is hope. Here's some pics

Owelly put his plenum on the other head and extended the pipe. This was cos he had room at the front, but was tight to the bulk head.

He the put a 90 degree bend on the end

two sets of triumph 3 cyl throttle bodies (which cost pennies on ebay) plus megasquirt, does away with the dizzy and the plenum in one go, just a manifold to make.
