I do remember seeing 3.0 casted on the back of the heads on my Verde. Do you want me to stick a clay on it, see if it's still there?

So I take it you have correct matching early 15 tooth oil pump driven gear to go with early 10 tooth drive gear and all is well for driving Milano 3.0L engine dizzy at correct speed?

Actually, that's what I ordered from Larry at APE with the sprocket. So that's the next update- once they arrive.

Thanks,

The simple way to tell the difference would have been to see if the head had the studs for the engine mount bracket behind the cam gear. The 164 would have studs and the Milano would not.

1969 1750 Spider Veloce w/dual webers, 1969 1750 Berlina, 1971 1750 Spider Veloce w/ dual webers, 1985 Spider Veloce 23,000 orig. miles, {Two} 1986 Spider Veloces, 1987 Spider Veloce bought new, 1988 Quadrifoglio, 1991 164S, Plus several more. I think they are breeding.

That is fine for determining what engine his left head came from.

But, his "problem" or issue was what engine his right head came from.
If it was a 164 head, was it early or late 164 head and did he have correct drive and driven gears to drive Milano distributor.

I don't see any studs near the area you say.



Thanks,

The 15 tooth steel gear with the notches in it is to drive distributor on GTV6 or Milano at correct speed and is also used in early 164B/L engines. It has to have a 10 tooth brass gear to mesh with it.

The 15 tooth steel gear with no notches in top of it has to mesh with 14 tooth brass gear used in 164S and later 164L engines and will not drive a distributor. It also drives the 164 oil pump at faster speed.

Thanks Steve. I ordered another from APE. It's installed and turns over by hand without issue.
