FOR SALE: Maserati 3500 GT Vignale Spyder engine 1960, dismantled for overhaul, complete as pictured, good condition, engine number AM101-1201

Specifications:

The engine is a nice 3500 GT Vignale Spyder engine with number AM101-1201. Maserati Classiche has confirmed it is the original engine of Vignale Spyder AM101-1201, also based on the internal engine number 597.
The engine is complete with all internals and also with the cam covers and end-caps, flywheel and used clutch, front pulley and oil dip stick.

It came to me dismantled for overhaul, this way it is easy to overview all essential parts are present as visible on the pictures. I do know the valve wedges ("half moons") are missing and some nuts and washers. It is also missing one liner, which is obtainable new. The rest is all present.

The block is very nice with its original main bearing caps (numbered 597), its internals and also the head studs are not very corroded. The liners (only 5 are present) will of course need a bore to an oversize or replaced with new ones.
All essential parts are there, like 5 timing gears and timing chain, crankshaft gears, drive for ignition distributor, oil pump with gear, cam shafts with mounting pieces for timing gears, oil tubes, front pulley, flywheel, clutch, etc.

The crankshaft has a main bearing size about 75,6 mm (2nd undersize of 4) and con rod bearing size about 56,6 mm (2nd undersize of 4) so fine for rebuild.

The con rods are a matching set with numbers 1 through 6 on both sides of the con rods.

The cylinder head looks nice with minor corrosion in the coolant areas. There is some light corrosion visible where the head gasket did not press, but nothing serious.
The height of the head measured through the head stud opening is 113,9, to my knowledge a new head is 114 mm, to give an indication on how often it was grinded.
It comes with a set of GT camshafts. They are regrinded and appear to never have been used since, so far very good. I have no information who did this regrind. I measured the heights of the cams and they are not all 100% equal, although the cam profiles look the same. So I guess they can be used with the use of slightly different shims.
The head is complete with cam shaft bearing caps, cam covers, end-caps (= 2 caps with Maserati logo, 1 rev-counter-cable connector and 1 oil filler neck with cap), valves, springs, washers on top of the springs, etc. Also present are the nuts for mounting the head.

Alternative cylinder head at reduced price:

I do have an alternative cylinder head which could be swapped instead of the head described above. It will need more work, but in my opinion it can be overhauled well. With this alternative cylinder head, I am willing to offer the engine for a lower price. Please ask if this interests you.

The head is complete with 8 camshaft bearing caps, but they are not original to this head. So the line bore needs to be checked and maybe corrected. There has been done some welding to the head too, visible in the pictures. With some work and a last re-grind, this head should be well to use. I will include the parts as used valves, springs, washers on top of the springs with the 'half moons'. Normally parts as valves, springs, valve guides and tappets are renewed, they can be bought new. The height of the head measured through the head stud opening is 113,25, to my knowledge a new head is 114 mm, to give you an indication on how often is was grinded.

This head came from a running engine many many years ago that needed an overhaul. Because there was some corrosion and another better head (came then with engine 101-1446) then was available, it was swapped. If you look at engine 101-1446 there is no corrosion visible, so its original head was probably also without corrosion. Much later the engine 101-1446 and this head changed owner and then it was welded to improve it. I bought engine 101-1446 and this head from this last owner and he told me the welding was done by a professional (without further proof). I had in mind that the original head gasket only consists of 6 cupper rings and a rubber covering only the outer border of 1 cm. So only these spots are important for sealing on the block. That’s how I bought it and it was intended for my own car.

Alternative crankshaft at reduced price:

I also have an alternative crankshaft which will need custom bearings: its main bearings are 74,92 mm (5th undersize or so, non-standard), con rod bearings are 55,92 mm (5th undersize or so, non-standard). With this alternative crankshaft, I am willing to offer the engine for a lower price. Please ask if this interests you.

Alternative set of con rods at reduced price:

And last I have an alternative set of con rods, where 2 will need some work or changing to make them identical to rest. With this alternative set of con rods, I am willing to offer the engine for a lower price. Please ask if this interests you.
