Title: 105 marked cams in GTV engine
Post by: kartone on November 03, 2010, 12:54:33 PM
Purchased a spare engine for my 1980 GTV, however upon disassembly found the cams to be stamped 105.....
Were 105 cams originally installed in GTV engines ? Or is what I purchased an hybrid (which will never run)?

I wouldn't be dissappointed . I would be jumping for joy. Putting 105 cams in your 116 Alfetta is/was a very sensible upgrade . Alfa post pollution cams (116 series) only have one use . Tomato stakes.

It's not the "105" number you want to see, it's the next digits.  "48" is good (as in 10548...) rather than "2003" (as in 1052003....). 

There are quite a few parts on an Alfetta that still have 105 part numbers. Camshafts are one.

Alister aren't 105---- camshafts specific to 105 series Alfa's and 116----- specific to Alfetta's. But a 10548 cam is a easily swapped to an Alfetta engine and helps produce the qualities of the sweeter & slightly more powerful  pre pollution engine.

Hi Paul,

Camshaft numbers carried over.  Some very early Alfetta's had 10548 cams, same as 105's whereas most had 1052003....

The full stamping on the cam shaft reads: 1054803  200.01
With the 548 cams what improves: power output, torque, responsiveness in general ?
Besides the installation and a tuneup, anything else?
