4 Valve Head Casting on EBay

I am surprised to see no discussion on the GTAm 4 valve raw head casting on EBay. Or is it somewhere else.

I passed on one of these that was used in an Alfa powered sports racer, many years ago in Miami. it was a complete engine with monosleeve, and had the cradle to hold the cams too. I later learned it went to Malaysia.

Just curious on cost to finish it.......

My guess, is much, much more than it costs.

My Gtam head 8V, was in bad shape, and it cost over $2K to repair
even though it was new, but has been fiddled on.

GTAm 4 Valve Auto Delta head

Hi Dave,
I purchased the GTAm 4 valve Auto Delta head in raw form, so I thought. The seller was offering it in the US, managed to convince him to send it to Australia.
There was another complete engine with mono sleeve, that had the cradle to hold the cams and some other spares that went to a very successful local 105 Alfa Romeo racing driver in Jakarta. I contacted him, but he sold most of the items except the spare cams and the new pistons. I was looking for a cradle to hold the cams and a cam cover and he did not have these.
I contacted a few engineers and they said I needed the drawings and the camshafts to have enough parts and dimensions to engineer the cam cradles and cam covers etc.

Then whilst looking for something else, I discovered I had the drawings all along, wow!, how lucky was that. The drawings list the dimensions of the head. To my surprise the head was actually 'semi finished' as it had the correct measurements when compared with the drawings, i.e. datum points were there. The head only needs valves installed i.e. angles, sizes and inlet and outlets ports and combustion chamber porting dimensions were also listed in the drawings.

I quickly got back to Jakarta and managed to acquire the 4 valve camshafts and a set of 4 valve pistons (At Chinese new year prices = 'very low prices').
At this point it is destined to go on my 1969 AR00551 engine/block and to run fuel injection.
Cheers Steve
p.s Happy Chinese New year on the 5th February 2019 every one.

Marcus Lipp in Austria is busy with one, he made up the cam cradles himself.
