    I have a 308 that Is in a boosted application, however lobe separation angle I think is very tight on the cam which means there is a lot of valve overlap between the intake and exhaust , when this type of camshaft is boosted a lot of raw fuel goes out the exhaust , does anyone know what the cam specs are on a quattrovalvole thanks in advance, specifically lobe separation angle

    The stock cam timing specs are given in each 308QV OM (and are a little different depending on which version). But, IIRC, all of CIS model F have what would be considered relatively little valve overlap (and is completely adjustable). You can download the 1983 US 308QV OM or 1984-85 US 308QV OM here if you don't have a copy:

    I didn’t realize it was in the owners manual
