Wille: What does that last column "rank" mean?

thanks

(Little) Washington, NC Incorporated 1776
Red 1959 Spider Conrero Veloce 100,000 miles
sold 1966 ( I had no idea what I had there.)
Red 1967 Spider 100,000 miles sold 1974
Red 1987 Milano 100,000 miles sold 1994
Red 1969 Spider 109,000 Miles in the garage, not for sale. (yet)

We need a law, one that says every male gets a 10 car garage on his 16th birthday so that when he is 60 years old he will never have to say "**** I wish I had never sold that car".
(No, I did not put those "****" up there the system did... )

Question: Do they really make Alfas in any other color then red?

The rank of the cam is referencing the Alfa Romeo DOHC Engine High-Performance Manual by Jim Kartalamakis. 1-4 is typically for street use. A higher rank represents more "performance".

Great book. In my opinion its a must read.

So turns out that the cams are the US style and not the euro spec. Explains a lot about the way the car ran.

I think you are not getting the chart info....

Prior to '68 when smog rules came to the US, there was no "euro" specific cams. Only by motor size and normale or veloce specs.

If you are fiting cams to a street 1750 or 2.0, the 10548 work well. Note the list for C&B cams and their performance rank.

Some used by Alfa on GTA racers !

I went thru this whole exercise and short of buying cams from Richard , if you want to keep the car streetable and limit the mods but get a little more bite, the euro cams you are looking for are the 001 and the 051 . they are very hard to find and depending on your economics , you might just be better off call up Richard and buying what you really need as part of your well thought out combination.

AFAIK the ranking numbers were devised by John Shankle, many years before the Jim K book.

10548 cams are not hard to find or expensive.
A lot of us have had great results using a 10548 on the intake and the Veloce cam on the exhaust. Nice smooth power !

Posting here because i don't want to start a new thread.
I seem to have stumbled upon a weird problem, i can't seem to get the valve seal to stay seated on the no.2 intake valve guide. It doesn't seem to be bottoming all the way on the guide and i can knock it off with a slight touch. All the other seals fit nice and snug, I'm assuming its more of a guide problem because when i took the valve out originally the seal wasn't on the guide or the valve infact it came out with the springs. I'm using victor reinz seals that look exactly like this. The old seals were a hard plastic that looked like this .
Playing around with the old seal it seems to fit all the way but still isn't as tight as i'd like it to be and will still occasionally pop off with the valve.

What is the original camshaft for a 1966 or 1967 GT Veloce? Is it 10502032001, listed as std 1600 cam, or is it 10121032000 listed as TI Super & Veloce cam?

What would be a good street upgrade for a stock 1600 GTV motor from 1966 with stock cams? If the above cam is stock and in the motor any cam would offer an improvement? Find it hard to imagine a 1600 GTV had the mildest cam?

Well on the cheap you can use a 10548 03200 01 on the intake only.
Real power however will come from proper modern cams designed for intake and the exhaust.

The 1600 cam follower bores are not chamfered as are the 2L so the 10548-51 will not fit without notching the cam follower bores.
