I got the engine out yesterday and stripped it down today.

Nothing too out of the ordinary to report, the bottom end bearings had a bit of scoring but nothing should have to be sent out to a machine shop, but I did have to make an adapter plate to mount it on my stand.

It’s just an old engine mount welded to a steel plate. Version 2 will have to be redesigned because while my welds held up fine, I did end up breaking a factory spot weld on the mount itself while rotating the engine over.

So basically my plan with this engine is a semi-hotrod build. I’m shooting for 160HP at the crank which will mostly come from top-end work. The bottom-end is already forged so all it really needs is a set of higher compression pistons and maybe a lighter set of rods.

In detail the build is going to be

10.5:1 pistons

(maybe) lightweight carrilo I-beam rods

windage tray

the cylinder head (when I find a replacement) will be sent out to be ported, have bigger valves fitted and be clearanced for the massive 12mm lift, 290 duration camshafts.

lightened flywheel

I’ll also re-do the exhaust properly instead of having mutiple pieces cobbled together from a junkyard car.

Should make for a nice rev-happy build albeit a bit expensive, I’ll probally end up spending close to the same amount of money building this engine that I spent building the 350 in the jag.

Isn’t that a really neat engine considering it came out in the 1960's! A baby offenhouser!

Sounds like a very cool build, looking forward to it!

The top pic makes the cylinders look very shallow, as if they were unsupported and mostly removed. It looks like a block on its way to getting sleeves to handle some serious pressure.

These alfa engine’s are somewhat unconventional where the cylinder liners are completely removable from the block and seal from the bottom using o-rings.

what is the o ring material?

I’m honestly not too sure, probably some variant of FKM.
