Jim, may I butt in? Isn't the valve clearance predicated on the cam rather than the engine type..? I think a cautionary note to the poster would include a question of what the cams are on a 50 year old car. Also some heads get swapped around over the years and cam timing marks are a bit variable based on where the head came from but won't effect valve lash.Please click below for the valve clearance page from Giulia SS user manual supplement #884 R1 dated 03/65.
In some cases, yes (the 00548 engine comes to mind). The 00121 engine was fitted to two models; the 10118 Spider Veloce and the 10121 Sprint Special. Both were fitted with the same 101.21.03.200.00 cams with identical clearance and timing specs. Of course, components could have been changed in the 50 years since the cars manufacture and use of a non-original cam/head may dictate different settings.Isn't the valve clearance predicated on the cam rather than the engine type..?
Commonly that is correct because of cam design (a slower opening and closing ramp)Isn't the valve clearance predicated on the cam rather than the engine type..?
