308 V12 conversion begins

The one manifold is pretty much done but still no wire for the camera so I can't post the pics I took.

 

found the cord. Now you can see what I''ve been up to.

The second manifold is ready for profiling.

I blued it, scribed it, and cut to the lines the best I could......like being back in 3rd grade again

The profile doesn't actually do anything but remove metal so milled to scribe lines and sanded to make it pretty is plenty good enough.

 

And then there were 2.

I still need to weld around inside the top flange and do a LOT of grinding but I think I'm going cut down the rest of the TBs first because I want to see them on the engine. These are tucked in about as tight as they can be tucked I think and I think with a little angle back cut on the upper flange the cam covers will clear to come off.

Thanks.

For me the key is to only move 1 direction at a time. I move away, move about over, move back to the line. I like to come up to the line from whichever axis is more sqare to the line, it seems easier that way. These took me about 1.5 hour each to cut the shape on.

 

Just a quick then/now. Way back when I first looked at the TBs on the heads with stock ports the runners all kinds of ran into each other…they don’t any more. I moved the ports a lot.

I don't know...maybe. I've done all I can to keep it short, but at this point it is what it is. I'm going to do another test fit once I get the other 10 TBs modified and on so we'll know in a few days if it fits.

 

Erik whos been over to help a couple times made a suggestion I like yesterday. The QV looking air box should pop off quickly/easily to show off the TBs inside and I think I can make that happen without a lot of effort. I was planning to make the bottom removable anyway to be able to get the injectors in, so this would just mean using ball plungers in detents or similar to hold the top/sides on instead of screws.

Here’s a picture that shows kind of what I’d have……it’s kind of an optical illusion, but it you stare at it long enough you should notice there is an F1 engine in the pic with the top of the air box removed
