EXCELLENT core cylinder head

2.0 L Alfa Weber Motor, Rebuilt, low miles. From valve cover to oil pan and cooling fan to pressure plate.
The story…

I bought this from a reputable repair shop in Rochester NY about ten years ago. It was pulled from a GTV. Tony the shop owner – who I still know and trust - said he built it and the owner had it in the car about “two summers”. It was originally a Spica engine that now has performance cams. DCOE 40’s. Piston Kit -10:1??? Bearings etc.
I was going to put it in a 1750 Spider project but that’s for sale now too.
The motor has been in my heated shop and has been sealed, fogged and turned over regularly.
I pulled the valve cover. Checked lash and chain tension and the cam and lifters. I rechecked the head torque properly loosening, lubricated nut/washers individually and retorqued to spec. Cam journals too. I pulled the Webers and cleaned them, set the float level and installed new but used carb mounts. Accelerator pumps function properly. They are mounted to a Euro 2.0L manifold. The oil was drained and new oil/filter installed. The oil system was forced pressure feed externally to insure everything was pre-oiled properly. The plugs were removed and the engine turned over with no fuel or ignition to ensure oil pump pressure was seen on a remote gauge. Plugs installed and it fired immediately on a remote fuel system.
The engine has been started and run several minutes. Ignition timing set. Carbs synched. A visual inspection of the intake and exhaust ports shows minimal carbon build up on the valves or ports as well as through the spark plug. Piston tops and valve/seat contact surface looks good.
No smoke. Fast cold starts and restarts. Great oil pressure – videos available.
Compression was checked. Cold engine/open throttle. Numbers approximately:
1/131 2/135 3/138 4/139
Electronic ignition
Webers fitted with: 30mm Venturis, 125 mains, 200 air, F16 emulsion tubes, 55F5 accelerators, 50F8 idle circuit. 35 needle/seat. Synched and good mounts. Euro manifold.
Cams – aftermarket - #10121032001 - Autodelta - from comments on the BB - both intake and exhaust are 10.2mm Lift. Lifters and lobes look good.
Clutch/ PP look near new – no issues
Alternator and voltage regulator included. Work properly and read 13,2 V at idle.
Currently the engine has a bat wing pan and pump installed for 1966 and up Alfa Spiders/GTV’s/Berlinetta.
I have nearly every combination of Giulietta/Guilia/Alfetta oil pan, oil pump, front water pump and exhaust header for your application.

I will disassemble to any level to confirm the integrity of engine/components for the cost of time and replacement materials. Can see/inspect running engine at my shop.

I have lots of photos of the individual cylinder compression results. Cold start. Warm oil pressure. Oil pressure rise etc I can send to interested parties if truly interested. Bring your Mics.

Engine is on a stand and I can demonstrate.


Complete running engine with clutch/flywheel/PP/electronic ignition/alternator/header $3500

Engine will be offered separately on the BB parts forum.

Or make me an offer for everything I can’t refuse ! – I need the space.

Jim G - Good catch. I'll dig up the proper front cover for the Spica system. I still have 5 blocks stashed away from my Group 3 Vintage race car days and just picked the wrong one......

Thanks Chris D
